Keep exports comparable
Use the same date range, index, link type, and domain or URL scope for every portfolio so missing coverage is not mistaken for an opportunity.
Backlink gap · supplied portfolio evidence
Find source hosts and pages that link to competitors but not you
Compare your retained backlink export with as many as three competitor exports. OpenWebmaster builds an exact intersection matrix, keeps source and destination evidence traceable, and exports every result without assigning invented authority or traffic value.

Ready for your real backlink portfolios.
No sample prospect, authority score, overlap count, or generated outreach claim appears before you supply evidence.
Practical backlink research
Turn source overlap into a qualified research queue
Verify the exact page
Confirm the source page still responds, inspect the destination and anchor, and check whether the visible editorial context fits your site.
Qualify before outreach
Review topical relevance, ownership, audience, spam risk, editorial standards, and a legitimate reason to contact the publisher.
