Backlink Gap Analyzer

What the Backlink Gap Analyzer does

The hardest question in link building isn’t "how do I get links" — it’s "which sites would plausibly link to me?" A backlink gap analysis answers it with evidence: sites already linking to your competitors have demonstrated they link out to content like yours. This tool compares your domain against up to 10 competitors and exports every gap domain to CSV or Excel.

Domains linking to two or three competitors are the priority tier — they link to your content category repeatedly, which makes them the warmest possible outreach targets. Vet each prospect’s quality with the Domain Authority Checker before spending outreach effort, and pair this with the Keyword Gap Analysis to close both gaps at once.

How to use it

1. Enter your domain, then up to 10 competitor domains.
2. Run the comparison and review domains linking to competitors but not you.
3. Prioritize domains that link to multiple competitors — they’re proven linkers in your niche.
4. Export to CSV, check each prospect’s authority and spam score, then build your outreach list.

Backlink Gap Analyzer FAQ

Why is a gap analysis better than cold link prospecting?

Because every domain in the gap list has already linked to content like yours — they’re proven linkers in your topic. Response rates on outreach to gap domains run far higher than cold prospecting from scratch.

Which competitors should I compare against?

Sites that rank for your target keywords with authority in your range. Comparing against giant brands produces a gap list full of links you can’t realistically earn; peers produce an actionable one.

What do I do with the gap list?

Qualify it first — check authority and spam scores, drop directories and scraped-content sites. Then look at what format earned each link (guest post, resource page, data citation) and pitch something of the same shape.
