The 15 Best B2B Google Shopping Ad Agencies for 2026

Google Shopping’s Quiet B2B Takeover

Somewhere right now, a buyer is typing a part number into Google with a budget already approved, and the supplier who wins that order is the one whose product feed answered first. 

Shopping ads capture 76% of U.S. retail search ad spend and 85% of all clicks across Google Ads campaigns, according to Google Ads benchmark data compiled by WebFX. That concentration of purchase intent used to belong to sneakers and skincare. Now it belongs to anyone with a SKU, whether that is a technology company selling devices and hardware, a manufacturer moving 40,000 industrial parts, or a services firm with a productized catalog. The buyers showed up. Most of the feeds did not.

Here is the uncomfortable part: The average B2B Shopping ads program was built on consumer logic, with generic titles pulled straight from an ERP, ROAS targets that ignore margin, and Performance Max campaigns spending freely with zero guardrails. According to Gartner’s Future of Sales research, 75% of B2B organizations will complete their highest-revenue deals through digital channels by 2028, which means the feed is no longer a side project for whoever has spare time in marketing ops. The agencies on this list treat Google Shopping as a managed revenue program with its own mechanics. We ranked them on performance, client reviews, and online sentiment, with a healthy mix of boutique specialists and big-name firms so you can find the right fit for your catalog and your CFO.

TL;DR — Top B2B Google Shopping Agencies

1. Directive: Directive is the strongest pick for B2B brands that want Google Shopping ads tied directly to margin and pipeline, whether you sell technology hardware, industrial components, or productized services. Directive builds product feed architecture around the part-number and spec-based searches B2B buyers run, structure campaigns by contribution margin before setting a single bid, and manage Performance Max with defined audience signals and exclusions.
2. ZATO Marketing: A paid-search-only micro-agency founded by Kirk Williams, one of the most respected Google Shopping and Merchant Center experts in the industry. ZATO pairs senior-only specialists with flat-rate, month-to-month pricing, so you get deep feed and Shopping expertise without junior hand-offs. A strong fit for brands that want the person managing their account to be the same person whose name is on the book about it.
3. Take Some Risk: A Vancouver boutique built on the conviction that 80% of Shopping success lives in the feed. Founder Duane Brown runs feed audits, Performance Max optimization, and Shopping campaigns for catalog-heavy brands across 25 countries. Ideal for companies whose product data needs surgery before their ad spend deserves to scale.
4. StubGroup: A Texas-based Premier Google Partner rated in the top 1% of Google’s partner program, with explicit B2B and SaaS focus alongside ecommerce. StubGroup is also the industry’s go-to for resolving Merchant Center and Google Ads suspensions, which matters because disapproved products kill visibility silently. A smart choice for B2B teams that want elite Google access with an insurance policy built in.
5. OMG Commerce: A Missouri-based Google Premier Partner that treats Shopping as one engine in a full-funnel Google program spanning Search, YouTube, and Microsoft Ads. Their dedicated Shopping practice includes feed management and multi-campaign segmentation, backed by CEO Brett Curry’s long-running ecommerce podcast. Best for product brands that want Shopping working in concert with video-driven demand.

Key Advantages of Working With a B2B Google Ads Shopping Agency

Let’s zoom in on what a strong Google Shopping ad agency delivers that internal teams and generalist media partners rarely manage on their own.

You Get a Product Feed Built for How B2B Buyers Actually Search

B2B buyers do not search like consumers. They type part numbers, MPNs, specs, and model numbers, and they expect the result to show exact pricing and availability before they ever click. A specialized product feed agency rebuilds product titles, attributes, and categories around that technical search behavior instead of the internal naming conventions sitting in your ERP. That single shift determines whether your highest-margin products appear in the auction at all. It also sets up your catalog for AI-driven discovery, where semantic richness and complete attributes decide which products surface in generated answers.

Because agencies manage feeds across many B2B catalogs, they know which attributes move impressions and which feed errors quietly tank eligibility. They run the transformation layer between your ERP and Merchant Center so catalog updates, pricing changes, and inventory shifts flow through without manual work. Your team stops firefighting data exports and starts reviewing revenue.

You Stop Optimizing for ROAS and Start Optimizing for Margin

A 5:1 ROAS looks great in a dashboard and can still lose money if it concentrates on your lowest-margin SKUs. Strong Shopping ad agencies segment campaigns by contribution margin before allocating a dollar of budget, so spend flows to the products worth advertising and away from the ones that erode profitability at any return. They also know that B2B order values, reorder cycles, and procurement timelines make consumer ROAS benchmarks meaningless for your business.

This margin-first lens changes the conversation with finance. Instead of defending click metrics, you report on which SKUs drove profit, which campaigns influenced pipeline, and how Shopping contributes to the revenue picture your CFO already tracks. Shopping stops being a black box of spend and becomes a line item leadership trusts.

You Keep Performance Max From Spending Like a Consumer Brand

Google’s automation defaults to the path of least resistance, which usually means brand-query cannibalization and low-intent clicks. An experienced agency runs PMax with defined conversion goals, layered audience signals, and active exclusions, so the algorithm amplifies your best buyers instead of your easiest ones. They monitor what the campaign is actually spending on, which most internal teams never see.

The same discipline applies to feed health. Products fall out of the auction silently when pricing or availability flags go unresolved, and revenue dips before anyone notices the cause. Agencies monitor eligibility continuously and resolve disapprovals fast, keeping your catalog visible while competitors troubleshoot in the dark.

You Protect Pricing Integrity While You Scale

Tiered pricing, contract pricing, and MAP agreements make B2B catalogs dangerous to advertise carelessly. Show the wrong price to the wrong buyer and you erode margin, anger distributors, and create channel conflict that costs more than the revenue Shopping generates. A B2B-fluent agency applies SKU-level rules that decide which products get advertised, which get excluded, and which get routed to a quote request instead.

That governance is what lets manufacturers and distributors run direct digital programs without blowing up the relationships their business depends on. It also keeps your Shopping presence consistent with your marketplace listings, distributor portals, and website, so buyers see one coherent brand at every price point. With the advantages clear, here is the full list of agencies worth your shortlist.

1. Directive

Margin-first Google Shopping Ads engineered for B2B buying behavior

We built our Google Shopping ads practice on a simple observation. B2B buyers arrive at the feed with a part number in hand and a budget approved, and the campaigns that win those orders are managed programs, never set-it-and-forget-it checkboxes. Our Shopping ads capability starts with feed architecture, building the data foundation that determines which SKUs get promoted, excluded, or routed to quote requests. We segment campaigns by contribution margin before setting a single bid, so budget concentrates on products that drive profit instead of products that flatter a ROAS report. We manage Performance Max with defined conversion goals, audience signal layering, and the negative discipline that keeps Google’s automation pointed at intent. When feed disapprovals threaten visibility, we resolve them within 48 hours. Every decision runs through DiscoverabilityOS, our methodology for connecting campaign execution to revenue.

What separates us from ecommerce PPC shops is that we understand how B2B sells, whether that is a technology company with hardware SKUs, an industrial distributor with 40,000 parts and tiered pricing, or a services firm with a productized catalog. We manage the transformation layer between your ERP and your feed platform, so catalog updates and pricing changes flow through without an IT project. Our Advertise, Exclude, or Route to RFQ framework protects MAP compliance and distributor relationships while you scale direct revenue. Companies like Sumo Logic, Betterment, and ActiveCampaign partner with us because we report the way their CFO thinks, on margin, pipeline, and revenue rather than impressions. Our Stratos platform ties Shopping performance into the same intelligence layer that powers the rest of your marketing mix. We do not chase cheap clicks. We build Shopping programs that turn your catalog into a revenue channel.

Google Shopping Ads Services: Google Shopping Campaign Management, Feed Architecture and Management, Performance Max Management, Microsoft Shopping Campaign Management, SKU-Level Margin Analysis, B2B Pricing Treatment Strategy, Cross-Channel Feed Strategy

All Services:  Shopping, Product Feed Management, Marketplace, Lifecycle Marketing, Paid Media, Programmatic, Content, Performance Creative, Revenue Operations, Startups, PR, Influencer, Organic Social, Paid Social

Standout Clients: Sumo Logic, Betterment, ActiveCampaign, 24Hr Supply, AVI-SPL, Accuris

Best For: B2B technology, industrial, and services brands that need Shopping ad performance tied to margin, pipeline, and revenue rather than vanity metrics.

Why Choose Directive:

• Margin-first campaign structure that decides which SKUs deserve budget before a single bid is set
• Feed architecture built for the part-number and spec searches B2B buyers actually run
• Pricing treatment framework that scales direct revenue without MAP violations or distributor conflict

2. ZATO Marketing

The micro-agency that wrote the book on Google Shopping

ZATO Marketing is what happens when one of the industry’s most respected Google Shopping minds decides to stay small on purpose. Founder Kirk Williams literally wrote the book on the discipline, authoring Ponderings of a PPC Professional and earning a spot on the PPC Hero Top 25 list for 10 consecutive years. The Montana-based shop only does paid search, with a deliberate focus on Google Shopping, Performance Max, and Merchant Center feed work. Every account is handled by senior specialists averaging roughly 10 years of experience, so there are no junior hand-offs or account manager layers between you and the work. Pricing is flat-rate and month-to-month rather than a percentage of spend, which keeps incentives aligned with performance instead of budget inflation. Client relationships tend to run long, including a 12-year engagement with 4Wall Entertainment.

The trade-off with a micro-agency is capacity, and ZATO embraces it rather than hiding it. They take on a limited roster, which means the founder’s feed philosophy shows up in actual account work instead of just conference talks. For B2B brands, that depth matters because spec-driven catalogs punish lazy title and attribute work faster than consumer products do. ZATO’s Merchant Center fluency translates directly to the part-number search behavior that defines B2B Shopping. They also extend coverage to Microsoft Ads and YouTube, so the feed investment works across more than one auction. If you want boutique attention from people who shaped how the industry thinks about Shopping, this is the shortlist entry.

Services: Google Shopping Ads, Performance Max, Google Merchant Center and Feed Optimization, Full-Service PPC, Microsoft Ads, YouTube and Demand Gen

Standout Clients: 4Wall Entertainment, Interweave Brands

Best For: Brands that want senior-only Google Shopping specialists with flat-rate pricing and zero account manager layers.

Why Choose ZATO Marketing:

• Founder-led Shopping and Merchant Center expertise recognized across the PPC industry
• Senior specialists on every account with no junior hand-offs
• Flat-rate, month-to-month pricing that keeps incentives tied to performance

3. Take Some Risk

Feed-obsessed boutique that treats product data as the campaign

Take Some Risk operates on a thesis most agencies only pay lip service to, that 80% of Shopping success is determined by the feed before any bid strategy matters. Founder Duane Brown built the Vancouver boutique in 2017 after in-house and agency stints that included ASOS, and the shop now runs campaigns in 25 countries. Their service menu reads like a feed specialist’s toolkit, with dedicated Shopping feed audits, feed optimization and management, and Performance Max work that includes the often-ignored PMax for Marketplaces format. That audit-first posture makes them especially useful for companies that suspect their product data is the real problem behind flat Shopping performance. Brands like Birdies, FTD, and WooCommerce have trusted the team with their paid programs. The boutique scale means the founder’s standards apply to every account rather than a rotating bench.

For B2B catalogs, the feed-first approach pays off quickly because technical products live or die on attribute completeness. A missing GTIN, a vague title, or an unmapped product type silently removes your SKUs from auctions your competitors are winning. Take Some Risk diagnoses those failures before scaling spend, which protects budget from amplifying broken data. Their PMax optimization work brings guardrails to a campaign type that loves to spend without explaining itself. They also run a training academy, which signals a team that can articulate why something works rather than just reporting that it did. For lean teams that need feed surgery more than another media manager, this is a sharp pick.

Services: Google Shopping Management, Shopping Feed Optimization and Management, Shopping Feed Audits, Performance Max Optimization, PPC Management, PPC Training

Standout Clients: Birdies, FTD, WooCommerce

Best For: Catalog-heavy brands whose product data needs diagnosis and repair before ad spend deserves to scale.

Why Choose Take Some Risk:

• Feed audits and optimization treated as the foundation of Shopping performance
• Performance Max expertise that includes the overlooked PMax for Marketplaces format
• Founder-led boutique standards applied across campaigns in 25 countries

4. StubGroup

Top 1% Google Partner that rescues suspended Merchant Center accounts

StubGroup has built one of the more distinctive reputations in paid search since its 2012 founding in Texas. The agency is a Premier Google Partner rated in the top 1% of Google’s partner program, and it explicitly serves B2B and SaaS companies alongside ecommerce and local businesses. That B2B fluency shows up in how they approach Shopping, with specialization across all 5 Google channels and campaign structures built for considered purchases rather than impulse buys. The agency reports more than $500M in client revenue generated, with case study work spanning industrial and commercial accounts like Site Fuel and Absolutely Electrical. Google itself featured StubGroup’s work with SuperBiiz in a published case study on mobile performance and ROAS growth. For teams evaluating partners on third-party proof, that is a useful signal.

The firm’s signature capability is one most agencies cannot offer, resolving Google Ads and Merchant Center suspensions. Anyone who has watched products silently fall out of the auction over a policy flag knows how expensive that downtime gets, and StubGroup has turned recovery into a productized specialty. That expertise doubles as prevention, since teams who know exactly how accounts get suspended build feeds that avoid the triggers entirely. It is effectively an insurance policy bundled into a management relationship. Combined with elite partner access to Google support channels, StubGroup gives B2B advertisers a level of account security that generalist shops cannot match. For companies whose revenue depends on staying eligible, that peace of mind is worth real money.

Services: Google Ads Management, Google Shopping, Merchant Center and Ads Suspension Resolution, Social Media Advertising, Email Marketing, Conversion Tracking and Strategy

Standout Clients: SuperBiiz, Site Fuel, Absolutely Electrical

Best For: B2B and SaaS companies that want top-tier Google partnership access with suspension recovery expertise built in.

Why Choose StubGroup:

• Premier Google Partner rated in the top 1% of Google’s partner program
• The industry’s go-to specialist for Merchant Center and Ads suspension recovery
• Explicit B2B and SaaS focus backed by a Google-published case study

5. OMG Commerce

Google ecosystem depth that pairs Shopping with YouTube demand

OMG Commerce approaches Google Shopping as one engine inside a complete Google ecosystem strategy rather than an isolated channel. The Springfield, Missouri agency is a Google Premier Partner with a dedicated Shopping management practice that includes feed management and multi-campaign segmentation. CEO Brett Curry has spent years publicly documenting what works through the eCommerce Evolution podcast, which gives prospective clients an unusually transparent window into how the team thinks. Their YouTube advertising practice is among the most developed of any agency this size, complete with search-lift studies that connect video impressions to purchase behavior. Shopping, Search, YouTube, and Microsoft Ads operate as a coordinated system, so demand created in one channel gets captured in another. Clients like BOOM! by Cindy Joseph and Macally have scaled on that full-funnel structure.

The multi-channel architecture matters for product brands because Shopping rarely wins alone. A buyer who watches a product demo on YouTube and later searches the part number is one journey, and OMG builds programs that treat it that way. Their feed management practice keeps product data competitive in the auction while the segmentation strategy concentrates budget on winning SKUs. Amazon advertising and brand management round out the offering, so brands selling across marketplaces keep their catalog strategy consistent. The agency skews toward DTC, which is worth weighing if your catalog runs deep into industrial complexity. For B2B brands with strong product stories and visual demos, the YouTube-plus-Shopping combination is hard to replicate.

Services: Google Shopping Management, Feed Management, Google Ads, YouTube Ads, Amazon Ads and Brand Management, Microsoft Ads, Email Marketing

Standout Clients: BOOM! by Cindy Joseph, Macally, YES Bar

Best For: Product brands that want Shopping coordinated with YouTube and the full Google ecosystem rather than managed in isolation.

Why Choose OMG Commerce:

• Dedicated Google Shopping practice with feed management and campaign segmentation
• YouTube advertising depth that builds demand Shopping campaigns then capture
• Google Premier Partner status with a public track record via the eCommerce Evolution podcast

6. Inflow

Senior specialists only, with no account managers in between

Inflow has been running ecommerce marketing since 2003 with a structural choice that defines the client experience. There are no account managers, so every client works directly with the senior specialist doing the work. That model attracts marketers tired of playing telephone through a coordinator who relays questions to the person who actually knows the answer. The agency is a Google Premier Partner and Meta Business Partner with a 97% client retention rate, which suggests the model holds up over time. Their published results include a Google Shopping case study showing a 268% revenue increase and a Performance Max engagement that lifted revenue 76.3%. Clients like KEH Camera, Vitrazza, and Gaia have built sustained programs on that senior-only structure.

The direct-access model has real implications for B2B Shopping work, where the details of feed structure and campaign segmentation reward expertise over process. When the person optimizing your product titles also answers your emails, feedback loops shrink from weeks to days. Inflow surrounds paid search with SEO, CRO, and email, so Shopping clicks land on pages built to convert and feed a retention program afterward. Their analytics practice keeps GA4 and measurement honest, which matters when Shopping revenue claims need to survive CFO scrutiny. The agency serves lead generation and B2B clients alongside ecommerce, so considered-purchase dynamics are familiar territory. For mid-size brands that value direct senior relationships over big-agency polish, Inflow earns its retention numbers.

Services: Paid Search Management, SEO, CRO, Paid Social Advertising, Email Marketing, GA4 and Analytics

Standout Clients: KEH Camera, Vitrazza, Gaia

Best For: Mid-size brands that want direct access to senior specialists and published Shopping results without account manager layers.

Why Choose Inflow:

• No account managers, so clients work directly with senior specialists
• Published Google Shopping and Performance Max case studies with verified revenue lifts
• 97% client retention built over 2 decades of ecommerce focus

7. JumpFly

2 decades of PPC discipline with a true in-house feed practice

JumpFly has been managing paid search since 2003, and longevity in this industry usually signals operational discipline rather than luck. The Chicago-area agency is a Google Premier Partner in the top 3% of the program and a Microsoft Advertising Elite Partner, with a 98% client retention rate and an A+ BBB rating. What earns JumpFly a spot on a Shopping-specific list is its dedicated feed management service line, a genuine practice with daily feed uploads, title and description optimization, custom labels, and product type restructuring. Google featured their work with Nature Hills Nursery in a published case study after Shopping clicks grew from 1M to 2.25M. Clients like Jura and Walk-In Lab round out a portfolio that spans considered purchases and technical products. The agency pairs Shopping with paid social, Amazon advertising, SEO, and email for full-program coverage.

Feed management as a named discipline matters more than it sounds. Plenty of agencies claim feed optimization while actually outsourcing it to a software subscription, and the difference shows up in how quickly disapprovals get resolved and how precisely titles match search behavior. JumpFly’s daily upload cadence keeps pricing and availability accurate, which protects eligibility for catalogs where stock moves fast. Custom label work enables the margin-based segmentation that separates profitable Shopping accounts from busy ones. For B2B sellers, that infrastructure handles the spec-heavy catalog data that generalist shops fumble. JumpFly is not the flashiest name on this list, and that is rather the point. The work is consistent, documented, and built to last.

Services: Full-Service PPC Management, Feed Management, Paid Social, Amazon Advertising, SEO, Email Marketing

Standout Clients: Nature Hills Nursery, Jura, Walk-In Lab

Best For: Companies that want steady, documented PPC management with a real in-house feed practice and daily feed hygiene.

Why Choose JumpFly:

• Dedicated feed management practice with daily uploads and custom label segmentation
• Google Premier Partner in the top 3% with a Google-published Shopping case study
• 98% client retention across more than 2 decades of paid search

8. AdVenture Media Group

The agency Google tapped to teach Google Ads to a million students

AdVenture Media Group built its reputation on an unusual credential, education at massive scale. Founder Isaac Rudansky’s Google Ads courses have trained more than 1M students, and the firm was chosen by Google to help train Google’s own teams. That teaching DNA shapes how the New York agency operates, with strategies explained in plain language rather than hidden behind dashboard exports. The firm manages more than $50M in annual ad spend across Google Ads, Meta, and LinkedIn, with CRO and landing page design closing the loop between click and conversion. Clients have included Forbes, Hanes, and Tyler Technologies, the last of which signals real B2B and government-adjacent fluency. Their proprietary Sherpa platform adds media mix modeling and attribution depth that most mid-size agencies cannot offer.

For B2B advertisers, AdVenture’s lead generation pedigree is the draw. Shopping campaigns for technical catalogs eventually collide with quote-based selling, and an agency fluent in both transactional and lead-gen motions can route products accordingly. The LinkedIn practice lets B2B brands surround Shopping intent with account-targeted awareness, a combination pure ecommerce shops rarely run well. Sherpa’s attribution modeling helps answer the question every B2B CMO eventually asks, which is what actually influenced the deal. The agency’s educational instincts make them a strong partner for in-house teams that want to get smarter rather than more dependent. If your Shopping program needs to coexist with a complex B2B funnel, this team understands both sides of that equation.

Services: Google Ads Management, Meta Ads, LinkedIn Ads, CRO and Landing Page Design, Full-Funnel Lead Generation, Media Mix Modeling and Attribution (Sherpa)

Standout Clients: Forbes, Hanes, Tyler Technologies

Best For: B2B companies that need Shopping integrated with lead generation, LinkedIn, and attribution across a complex funnel.

Why Choose AdVenture Media Group:

• Education-first approach from the team that trained more than 1M students in Google Ads
• Proprietary Sherpa platform for media mix modeling and attribution
• Strong B2B and lead generation fluency alongside paid media management

9. Solutions 8

Performance Max specialists who show their work in public

Solutions 8 has become one of the most visible Google Ads agencies in the world largely by giving away its playbook. The Scottsdale-based Google Premier Partner publishes a constant stream of Performance Max teardowns, tutorials, and strategy breakdowns on YouTube, which means you can audit how they think before you ever book a call. The agency manages more than $100M in ad spend across 200+ clients, spanning ecommerce, lead generation, and SaaS. That mix matters for B2B advertisers because Solutions 8 understands both the transactional Shopping motion and the longer consideration cycles that define business purchases. Clients like PetMeds, Comfort One Shoes, and IFAW have scaled on their campaign frameworks. The team also runs a white-label fulfillment arm, which speaks to systematized processes rather than hero-dependent account management.

PMax expertise is the headline reason to consider them. Google keeps pushing advertisers toward automation, and the gap between a guarded PMax campaign and an unguarded one is often the entire margin of a Shopping program. Solutions 8 has spent years documenting exactly where Google’s automation helps and where it quietly burns budget, and that knowledge compounds in account work. Their content marketing and email capabilities extend programs beyond the click. One honest note, the founder exited the agency in 2022, so you are buying the system rather than a famous name, and the public content trail suggests the system survived the transition. For advertisers whose Shopping strategy now runs through PMax whether they like it or not, this team knows the machine.

Services: Google Ads Management, Performance Max, Amazon Ads, Meta Ads, Email Marketing and Klaviyo, Content Marketing, White-Label PPC Fulfillment

Standout Clients: PetMeds, Comfort One Shoes, IFAW

Best For: Advertisers whose Shopping strategy depends on Performance Max and who want specialists fluent in Google’s automation.

Why Choose Solutions 8:

• Deep Performance Max expertise documented publicly in teardowns and tutorials
• More than $100M in managed spend across ecommerce, lead gen, and SaaS
• Systematized processes proven by a white-label fulfillment practice

10. KlientBoost

The SPAG inventors with a case study library to prove it

KlientBoost coined the Single Product Ad Groups methodology, which gave Shopping advertisers SKU-level bid control years before the rest of the industry caught on. That inventive streak still defines the Costa Mesa agency, which has grown to more than 80 people serving 250+ clients across paid search, paid social, CRO, SEO, and email. Their case study library is the largest of any agency on this list, with hundreds of published, named examples rather than anonymized teasers. B2B and SaaS work is core to the agency’s DNA, with clients like Airbnb, Segment, and Hotjar in the portfolio. The CRO practice is the quiet differentiator, because Shopping clicks on technical products frequently land on pages never designed to convert procurement-minded buyers. KlientBoost treats the landing experience as part of the media buy.

The agency’s testing culture suits B2B Shopping accounts where assumptions imported from consumer ecommerce tend to fail. Bid strategies, title structures, and audience layers all get tested against revenue rather than adopted on faith. Their SaaS fluency means they understand lead quality conversations, sales cycle math, and the difference between an MQL and a deal. For companies running Shopping alongside demand gen campaigns, having one team manage both keeps budget decisions coherent. The publish-everything posture also creates accountability, since an agency that names its results publicly has fewer places to hide. For B2B brands that want aggressive testing with documented receipts, KlientBoost belongs on the shortlist.

Services: Google Ads and PPC Management, Paid Social, CRO, Landing Page Design, SEO, Email Marketing

Standout Clients: Airbnb, Segment, Hotjar

Best For: B2B and SaaS companies that want Shopping paired with aggressive CRO and a testing-first paid media culture.

Why Choose KlientBoost:

• Inventors of the Single Product Ad Groups methodology for Shopping control
• Hundreds of published, named case studies for accountability
• CRO and landing page practice that converts technical Shopping traffic

11. SmartSites

SMB powerhouse with industrial B2B Shopping receipts

SmartSites has turned small and mid-size business marketing into a repeatable science since brothers Alex and Michael Melen founded the New Jersey agency in 2011. It holds Google Premier Partner and Microsoft Elite status, with one of the largest review footprints in the industry across Clutch and other platforms. The portfolio includes 143 filterable case studies, 21 of them specifically covering Shopping and ecommerce ad campaigns, which is the kind of paper trail that simplifies vendor evaluation. Crucially for this list, SmartSites has real industrial B2B work, including AGA Parts, a heavy truck and machinery parts seller whose catalog is exactly the kind of spec-driven inventory that breaks consumer playbooks. Clients like Hat Heaven and R&Y A/C Compressors round out a roster that spans retail and technical commerce. Web design, SEO, social, and email sit alongside PPC for full-stack coverage.

The SMB focus translates to pricing and processes built for companies without enterprise budgets or procurement departments. SmartSites moves fast, documents results, and does not require a 6-month onboarding to show momentum. For parts sellers and distributors, the AGA Parts work demonstrates fluency with massive SKU counts, fitment-style search behavior, and the unglamorous feed maintenance that keeps those catalogs eligible. Their ecommerce ads management covers Google Shopping alongside Microsoft, capturing the Bing-heavy procurement audience many agencies ignore. The breadth does mean less of the boutique founder attention you get higher on this list. For growing B2B sellers that want proven systems at accessible scale, SmartSites delivers volume without sloppiness.

Services: PPC Marketing, Google Ads Management, Ecommerce Ads Management, SEO, Web Design, Social Media Marketing, Email and SMS Marketing

Standout Clients: AGA Parts, Hat Heaven, R&Y A/C Compressors

Best For: Small and mid-size B2B sellers, including parts and equipment companies, that want documented Shopping results at accessible pricing.

Why Choose SmartSites:

• 21 published Shopping and ecommerce campaign case studies among 143 total
• Proven industrial B2B work with spec-heavy, high-SKU catalogs
• Google Premier Partner and Microsoft Elite status with SMB-friendly processes

12. Logical Position

Proprietary feed technology inside an award-winning Premier Partner

Logical Position brings something rare to the Shopping conversation, proprietary feed management technology backed by an in-house data feed team. Their FeedLogic platform structures and optimizes product data across Google Shopping, Microsoft, and Facebook, automating the rule-based work that determines auction eligibility at scale. The agency sits in the top 1% of managed ad spend among Google partners and has collected serious hardware, including Google’s Lead Generation Premier Partner of the Year and Microsoft’s Global Channel Partner of the Year for 2024. Selection into the Google Partners International Growth Program means clients expanding into new markets get structured support most agencies improvise. Clients range from WOLFpak and Ironman 4×4 to Needlepoint.com, with enterprise names like Bausch + Lomb in the broader portfolio. The full-service menu spans PPC, SEO, paid social, email, and Amazon advertising.

For high-SKU B2B catalogs, the FeedLogic advantage compounds. Manual feed management breaks down somewhere around a few thousand products, and the companies on this list with 10,000+ SKUs need automated rules for pricing treatments, exclusions, and label-based segmentation. Logical Position built that infrastructure in-house rather than reselling a software subscription, which means the feed team and the campaign team share one roadmap. The lead generation award matters for B2B too, since plenty of technical products convert through quote requests rather than carts. Their scale brings process maturity, dedicated support, and the partner-level access that gets problems escalated inside Google quickly. For catalog-heavy advertisers who have outgrown manual feed work, this is the infrastructure play.

Services: PPC Management, Google Shopping Ads, Product Feed Management (FeedLogic), SEO, Paid Social, Email Marketing, Amazon Advertising

Standout Clients: WOLFpak, Ironman 4×4, Needlepoint.com

Best For: High-SKU catalogs that need automated, in-house feed technology and top-tier partner access at scale.

Why Choose Logical Position:

• Proprietary FeedLogic platform with a dedicated in-house data feed team
• Google Lead Generation Premier Partner of the Year and Microsoft Global Channel Partner of the Year 2024
• Top 1% of managed ad spend with structured international expansion support

13. Disruptive Advertising

Audit-first paid media from one of the most reviewed shops in performance marketing

Disruptive Advertising has built a 150-person operation in Utah on a simple premise, that most ad accounts waste a meaningful share of their budget and the fastest win is finding it. Founder Jacob Baadsgaard started the agency in 2012 around forensic account audits, and that diagnostic instinct still anchors how engagements begin. The firm manages more than $450M in annual ad spend and bills itself as the most 5-star reviewed performance marketing agency, a claim its review footprint largely backs up. Service lines span paid search, paid social, Amazon advertising, SEO, CRO, and lifecycle marketing, with dedicated B2B and ecommerce practices. Their 90-day measurable-growth commitment puts early pressure on results rather than letting engagements drift. Reported client work includes names like Guitar Center, Adobe, and KPMG.

For B2B Shopping advertisers, Disruptive works best as a consolidation play. Companies juggling separate vendors for search, social, and lifecycle can bring the full paid program under one roof with enough headcount to staff it properly. The audit-first methodology surfaces the margin leaks that accumulate in Shopping accounts, from brand cannibalization inside PMax to budget pooled on low-margin SKUs. Their CRO and lifecycle practices extend Shopping wins into repeat purchase behavior, which is where B2B catalog economics get interesting. The agency is large enough that fit depends on your team and tier, so ask directly about who staffs the account. For advertisers who want scale, reviews, and a results deadline in the first quarter, Disruptive makes a strong case.

Services: Paid Search, Paid Social, Amazon Advertising, SEO, CRO, Lifecycle and Email Marketing

Standout Clients: Guitar Center, Adobe, KPMG

Best For: Companies consolidating paid media with one larger partner that leads with forensic account audits.

Why Choose Disruptive Advertising:

• Audit-first methodology that finds wasted spend before scaling budgets
• More than $450M in annual managed spend with deep review credibility
• 90-day measurable-growth commitment that front-loads accountability

14. Wpromote

Enterprise challenger marketing with serious Google partnership muscle

Wpromote operates at a tier most agencies on this list do not touch, with Ad Age Performance Marketing Agency of the Year honors and a Google Premier Partner of the Year award on the shelf. The firm’s “challenger” positioning means it builds programs for large brands that still want to take share rather than defend it. Paid search and Shopping sit inside a full-funnel architecture spanning paid social, SEO, programmatic and CTV, affiliate, influencer, and creative. The proprietary Polaris IQ platform handles forecasting, budget allocation, and measurement across that mix, giving enterprise marketers one analytical brain over many channels. Client work includes Whirlpool, TransUnion, and Frontier Airlines, with the TransUnion engagement standing as a genuine B2B proof point. Insider partner access with Google and BigCommerce keeps the team early on platform changes.

Enterprise B2B brands evaluating Wpromote are usually buying orchestration rather than a single channel. Shopping campaigns at that scale interact with retail media, marketplace strategy, and brand investments, and an agency that measures across all of them prevents the channel-by-channel budget fights that stall growth. Polaris IQ’s media mix modeling answers board-level questions about incrementality that account managers at smaller shops cannot. The trade-off is obvious, since minimum engagement sizes and enterprise processes make Wpromote impractical for lean teams. Their Google relationship means access to betas and escalation paths that materially affect Shopping performance. For B2B organizations with enterprise budgets and multi-channel complexity, Wpromote is the grown-up in the room.

15. WebFX

The 500-person machine with industrial-strength Shopping feeds

WebFX is the largest independent shop on this list, a Pennsylvania operation 25+ years old with hundreds of in-house specialists and a claimed $10B+ in client revenue driven. Scale aside, it earns a Shopping-specific mention for having dedicated service lines most big agencies lack, including Google Shopping management and a standalone shopping feed management offering covering Merchant Center data optimization. The proprietary MarketingCloudFX platform ties campaign data to revenue tracking, which suits B2B companies tired of reporting that stops at the click. The client bench runs unusually deep into industrial territory, with names like Thompson Tractor, ALL-TEST Pro, and Sharretts Plating, exactly the kind of spec-catalog businesses this article is for. SEO, AI search optimization, web design, content, and social round out a full-service menu in the truest sense. Google Premier Partner status applies here as well.

The honest framing is that WebFX is a system, with documented processes, predictable deliverables, and pricing published more transparently than almost any competitor. That works beautifully for B2B companies that want a dependable machine and dedicated tools without boutique pricing opacity. The industrial case study depth means your feed will not be the first ERP-exported mess the team has untangled. Their AI search work also positions catalogs for the answer-engine discovery that increasingly precedes B2B purchases. You will not get a famous founder reviewing your account, and at this scale nobody should expect it. For B2B organizations that want Shopping, feeds, and the entire digital presence handled by one accountable vendor, WebFX closes this list with the broadest offering on it.

What to Consider When Hiring a B2B Google Shopping Ads Agency

Start with the feed, because any agency that opens the conversation with bid strategies before asking about your product data is solving the wrong problem first. Look for proof they understand B2B selling mechanics, including tiered and contract pricing, MAP compliance, distributor relationships, and the part-number search behavior of engineers and procurement teams, whether your business is a technology company, an industrial manufacturer, or a services firm with a productized catalog. Ask how they structure campaigns around contribution margin rather than blended ROAS, how they put guardrails on Performance Max, and how fast they resolve feed disapprovals before silent ineligibility becomes a revenue dip. Demand reporting that speaks in margin, pipeline, and revenue, since impressions and clicks will not survive a conversation with your CFO. Finally, weigh how Shopping connects to the rest of your go-to-market, because a feed strategy that ignores your marketplace presence, distributor portals, and website pricing creates the channel conflict it should prevent. We built Directive’s Shopping Ad practice around exactly these criteria, which is why margin-first structure, feed architecture, and revenue-level reporting come standard rather than by request.

The Feed Is the New Storefront

The quiet truth about B2B commerce in 2026 is that your product feed now works the room before your sales team ever gets the meeting. Buyers compare specs, pricing, and availability inside the auction, AI answer engines read your attributes to decide whether you exist, and the suppliers winning those moments are the ones who treated product data like infrastructure instead of an export task. The agencies on this list all understand that shift. The difference between them is how directly they connect Shopping execution to the numbers your business actually runs on.

Choosing the right partner depends on your catalog, your channel relationships, and how much complexity sits between your ERP and a clean feed. A boutique might be perfect for a focused catalog, while a high-SKU distributor juggling MAP agreements needs deeper infrastructure and stricter governance. We built our Shopping practice for exactly that second kind of problem, with margin-first campaigns, feed architecture engineered for B2B search behavior, and reporting your CFO will recognize.
