A backlink gap is the difference between your site and your competitors' sites in terms of referring domains. Specifically, it's the list of domains that link to your competitors but have never linked to you — these are your link building opportunities. Backlink gap analysis, also called link gap analysis, helps SEOs and website owners prioritise outreach by targeting sites already proven to link within their niche.
