Link Gap Finder
Find sites linking to your competitors but not to you.
Link Gap Finder is free - sign up to run it.
This tool uses live SEO data, so we ask for an email - that's it. Every account gets 1 free run of every advanced tool, every month. No card, no spam, no upsells.
Earning new backlinks is most efficient when you target sites that already link to similar businesses - they've shown they're willing to link to your space. This tool compares your domain's backlink profile against a competitor's and surfaces domains that link to them but not to you. Each result includes the linking domain, its DataForSEO domain rank, how many backlinks they're sending to the competitor, and when they first started linking. Use the list as your outreach short-list: pitch a relevant page on your site to the same domains. Pre-vetted prospects beat cold outreach 10:1 because the domain has already demonstrated it links to your category. Sign up free for one analysis per month - we run multi-competitor gap audits as part of our consulting service.
Frequently asked questions
How many domains should I target from the gap list?
Start with the top 20 by DataForSEO rank. Higher-rank domains pass more authority. After 20, focus on relevance over rank - a niche industry blog often beats a higher-DR generic site.
What's the success rate of cold outreach for these?
Pre-qualified gap-list prospects convert at 5-15% with a thoughtful pitch. Generic cold outreach usually converts under 1%.
Can I compare against multiple competitors?
This version is one-vs-one. Multi-competitor comparison (2-3 competitors at once) is part of our consulting work - book a call.
Does this filter out low-quality sites?
It sorts by DataForSEO domain rank, so the top results are the highest-authority domains. You should still manually vet for relevance and quality before outreach.
