MARKETPLACE ADVERTISING AGENCY FOR B2B

Turn Marketplace Ad Spend Into Profitable Revenue, Not Vanity ROAS.

Your buyers already shop Amazon, Walmart, and the marketplaces. The real question is whether your ad spend is building margin or just buying impressions. We run B2B marketplace advertising tied to contribution margin, so every dollar has a job before it goes to work.

Marketplace Advertising That Starts with Margin, Not a Campaign Plan

OUR B2B AGENCY METHODOLOGY

Most marketplace advertising starts with a campaign and hopes the math works out. We start with the financial model. Our DiscoverabilityOS methodology sizes contribution margin by SKU first, so we know which products to advertise, which to exclude, and which to route to RFQ before a single dollar moves.

This page is the advertising-focused expression of our broader Marketplace capability, the part that turns Amazon, Walmart, and retail media spend into profit you can defend to a CFO. The outcome is not a higher ROAS screenshot. It is qualified revenue at a margin that holds up.

Ad Budgets Are Pouring into the Marketplaces, Whether You're Ready or Not

is where US retail media ad spending is headed by 2028, an 88.5% jump from 2024
Retail media has become one of the fastest-growing channels in digital advertising, because it puts ad dollars next to buyers at the moment of purchase. For B2B brands, that shift is happening on Amazon Business, Walmart, and distributor platforms where buyers already research by part number and spec. The risk is not sitting out. It is spending into the channel with consumer tactics and watching margin disappear behind a healthy-looking ROAS. The brands that win treat marketplace advertising as a profit decision, not a media-buying exercise.

Our Process & Impact

HOW IT WORKS
We run marketplace advertising on a structured cadence built to compound profit, not just sustain spend.

The Marketplace Advertising Problems We Solve.

THE STRUGGLE
B2B brands pour budget into Amazon, Shopify, and Walmart, then can’t explain why revenue climbs while margin slips. We run marketplace advertising that ties every dollar to contribution margin, so growth shows up on the P&L, not just the dashboard.

ROAS that hides a margin problem

A 5:1 ROAS feels like a win, but on a thin-margin SKU it can still lose money on every order. We model contribution margin before launch, so spend targets the products that build profit.

Consumer tactics on a B2B catalog

Most agencies optimize listings for product names, while your buyers search by part number and spec. We build campaigns and content for how B2B procurement actually buys.

Ad spend into listings you don't control

Without the Buy Box, and with MAP violations and channel conflict, paid clicks send buyers to a broken purchase path. We fix feed and catalog control before scaling a dollar of spend.

No line from spend to revenue

Another dashboard nobody owns leaves leadership unsure what marketplace ads return. We connect spend to margin and influenced pipeline through Stratos, so the investment is defensible.

Frequently Asked Questions About Marketplace Advertising

FAQ
A marketplace advertising agency plans and manages your paid advertising on platforms like Amazon, Shopify, Walmart, and retail media networks. Directive does this for B2B brands and ties every dollar of spend to contribution margin and revenue, not just ROAS.
B2B buyers search by part number and spec, purchase through approved-vendor lists, and run longer, multi-stakeholder buying cycles. Consumer ROAS benchmarks and product-name tactics misfire here, so we build campaigns around how procurement actually evaluates and buys.
We manage Sponsored Products, Sponsored Brands, Sponsored Display, and DSP on Amazon, Shop Ads on Shopify, plus Walmart Connect and other retail media networks. We also handle Amazon Business strategy for B2B sellers and approved-vendor catalogs.
We measure on contribution margin, blended ROAS, and influenced revenue, not impressions or a single campaign’s ROAS. Reporting runs through Stratos so you can see what each channel returns at the profit level.
