How the Competitor Backlink Gap tool works
The tool reads your website to build a product profile, infers likely competitors, and samples pages linking to them. It excludes pages on your own domain and scores the remaining source pages for relevance. It does not fetch your backlink profile or verify that a source does not already link to you. Treat every result as a competitor backlink source to review, not a confirmed gap; backlink indexes can also be incomplete.
Results are categorized by opportunity type:
Resource pages — curated link lists where a competitor appears in the sampled data. Check whether your site is already listed, then whether your resource adds something distinct.
Blog mentions — individual posts that reference a competitor in context. If your product solves the same problem, you have a factual basis for outreach: the site has already written about this topic.
Link roundups — recurring content digests that included a competitor. Getting added to the same roundup is often a matter of submitting for future editions.
Niche blogs — other source pages that mention or link to a competitor. Their editorial purpose needs a manual check before outreach.
Each result shows which competitor the linking site references, giving you context for how to frame outreach.
Three ways founders use this tool
Finding specific candidates to check. If a resource page links to competitors and your product is a credible addition, open the page. Check whether it already links to you, then identify the exact reader benefit before suggesting an addition to an editor. A competitor link alone is not evidence that your pitch will be accepted.
Understanding your competitive link landscape. Before building any link-building strategy, knowing which sites are actively linking into your category tells you which editorial relationships matter most. If ten high-quality sites all link to the same competitor, that competitor has category authority you need to close.
Prioritizing outreach effort. Not every candidate source is worth pursuing. Read the source page, check whether it already links to you, verify topical fit and real readership, and identify the exact resource you would suggest. The Backlink Price Calculator offers a rough economic estimate, but should not outrank page and audience fit. For a broader discovery workflow, see how to find backlink opportunities or try the Backlink Opportunity Finder.
Example: turn a gap into an outreach decision
Imagine your B2B SaaS product helps teams prepare sales calls. The report finds a sales-enablement resource page linking to two competitors. Open that page first. If it lists products solving the same job and your product has a genuinely different capability, record the page URL, the relevant section, and a concise reason its readers might benefit. Then find the editor and suggest that addition. If the link is a paid sponsorship, a customer quote, or an old article that is no longer maintained, skip it. A shared referring domain alone is not a pitch.
What the tool cannot tell you
Competitor backlink data comes from a sampled index and may miss inbound links, particularly from newer or smaller sites. The scan does not check your own inbound links at all, so it cannot establish a confirmed gap.
The tool also can't tell you why a site linked to your competitor specifically. Sometimes it's a genuine editorial endorsement; sometimes it's a paid placement or a reciprocal arrangement. Read the source page before outreach to understand the link context.
