What is a backlink overlap analysis?
Backlink overlap analysis compares the referring domains pointing to two or more competitor sites. Domains that link to multiple competitors are high-value outreach targets, and domains that link to competitors but not to you reveal clear link-building gaps.
Why use a backlink analyzer
- • Find shared referring domains across competitors
- • Identify link gaps where competitors get links and you don't
- • Prioritize outreach to domains already willing to link
- • Process large CSV exports without hitting tool seat limits
