Key Features & Benefits: The SEO Toolkit on SEMrush features four different tools to help digital marketers streamline and manage their link building efforts:

  1. Backlink Analytics – Marketers can enter any domain or URL and gather comprehensive data on that domain’s backlinks.
  2. Backlink Audit – Marketers can analyze their own backlink profile, identifying any toxic or spam backlinks that need to be removed. SEM rush automatically scores backlinks by how toxic they are, making it easier than ever to complete a backlink audit.

Check My Links Extension

Check My Links Chrome Extension

Overview: Check My Links is a Google Chrome extension tool release for free by the developers at Page Modified. This tool makes it quick and easy to check for broken links on your own web pages, but it’s also your window into a useful and under-rated type of link prospecting known as broken link building.

Key Features & Benefits: Digital marketers can use Check My Links to start generating outreach opportunities that can result in valuable new backlinks. Here’s how to make it happen:

  1. Instead of checking your own website for broken links, use Check My Links to check for broken links on a website that you would like to get a backlink from.
  2. Find a broken link that could be replaced with a link to relevant content on your own website.
  3. Find the email address for the owner of the website with the broken link.
  4. Send an outreach email to let the website owner know about the broken link and ask if they could replace it with a link to your content instead. They will most likely say yes because they want to fix the broken link and you’re coming to them with a solution already prepared.
  5. Congratulations – you just build a high-quality backlink!

Pricing & Access: This tool is available completely free of charge to anyone who uses the Google Chrome browser.

Key Features & Benefits: For many digital marketers, email outreach is a critical part of the overall link building strategy. When you’re targeting backlinks on high-trust, high-authority websites, simply publishing new content and hoping for the best isn’t enough – marketers must take an active role in promoting their content online.

Marketers can approach email outreach from several different angles to create different types of backlink opportunities. Here are just a few options:

  1. Building Infographic Backlinks – Marketers can invest time creating a brilliant infographic that’s relevant to their industry, then use email outreach to ask other websites to post their infographic along with a link back to the source page.
  2. Going for Guest Posting Opportunities – Marketers can use email outreach to develop guest posting opportunities where they write content for other websites and include editorial backlinks to their own pages.
  3. Broken Link Building – Marketers can email link building prospects to inform them of broken links on their websites and suggest replacing them with a link to relevant content on the marketer’s website.
  4. Requesting Editorial Backlinks – Marketers can use email outreach to simply share new content that other websites in their niche may want to link to in their upcoming content publications.

So, where exactly does Hunter.io come in? It allows digital marketers to quickly discover domain-linked email addresses to target with email outreach campaigns. It also includes an Email Verifier tool for ensuring that discovered email addresses are able to receive mail.
