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 the Competitors section. Serpfeed suggests likely matches automatically, and you can add your own, up to your plan’s limit. The more accurate your list, the more relevant your competitor gaps. See Tracking competitors for the full tour.
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 Competitor filter 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 section, 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 three tabs: Activity is a feed of what recently changed on the site, Pages lists its real pages from the sitemap with the best 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.
On the Backlinks tab, Show linking pages goes one level deeper: instead of just the domain that links, it reveals the exact page that contains the link, its anchor text, and the exact page on the competitor it points to, for every referring domain at once. That is the detail you need to plan how to earn a similar link. It costs 2 credits the first time and is then cached for two weeks, so viewing it again is free.
The referring page, right on your list
Your opportunities list has a Referring page column showing the exact page a competitor is linked from, so you can judge the target at a glance: /blog/best-payroll-tools is an editorial listicle worth an email. Links that appear site-wide (in a footer, nav, or partner strip) are marked site-wide instead of showing a page, since they are usually sponsorships you can’t replicate with outreach. Use the Referring link filter to show only editorial links and hide that noise. On paid plans this fills in automatically for your tracked competitors; on Free it appears once you use Show linking pages for a competitor.
