A backlink gap analysis aims to tell us which websites are linking to our competitors, but not to us. This is vital data because it allows us to close the gap between our competitors’ backlink profiles and start boosting our own ranking authority by getting links from websites that already link to competitors. Websites that link to multiple competitors (especially when it is more than three competitors) have a much higher success rate for us when we start reaching out to them and creating content for guest posts.
