The single richest source of link opportunities is your competitors. If a site already links to a business like yours, it is far more likely to link to you too. Serpfeed calls these competitor gaps, and finding them is what competitor backlink analysis does.

How it works
Serpfeed pulls the backlink profile of each competitor you added, then subtracts the domains that already link to you. What is left is a list of sites that link to your competition but not to you: warm, proven targets.
Why overlap matters
A domain that links to just one competitor is a decent lead. A domain that links to three or four of them is a much stronger one: it clearly links to businesses in your space, so your odds are better. Serpfeed shows this overlap so you can prioritize the domains that link to the most competitors first.
Adding and changing competitors
You pick competitors during onboarding, and you can change them anytime in Settings. Serpfeed suggests likely matches automatically, and you can add your own, up to ten per project. The more accurate your list, the more relevant your competitor gaps.
When you remove a competitor, Serpfeed asks whether to also delete the backlink opportunities that came from it, handy when a competitor (say a big news or government site) has great links you'll never realistically earn. Opportunities that only came from that competitor are removed; any also found via another competitor you still track are kept, just no longer tagged with the removed one. You can also keep them and instead use the Competitorfilter on the opportunities list to exclude a competitor's links from view, which works even for a competitor you've already removed.
Inspecting a domain
Open any competitor from the Competitors settings, or search for any domain with the search bar, to see its detail page. Alongside the domain overview (rating, traffic, and reach), the middle of the page has two tabs: Pages lists the site's real pages from its sitemap, with the ones that make good link targets flagged first, and Backlinks lists the domains that link to it, with their authority and whether the link is still live. From there you can add the domain as a competitor or as a link opportunity.
