A backlink gap analysis finds the websites that already link to your competitors but not yet to you. Those domains are the highest-converting outreach targets because they publish in your niche and have shown willingness to link to sites like yours. To run one, you compare several competitors' referring domains, subtract any that already link to you, and rank what remains by quality. This tool does exactly that: enter two to ten competitor domains plus your own, and the Link Gap view lists every source that links to rivals but skips you. Each entry shows Domain Authority, link type, anchor text, and which competitors it links to, so you can prioritise the strongest prospects first. Add your domain in the optional field above to unlock the gap view and start mapping outreach targets.

The opportunity score rates each link source from 0 to 100 based on how worthwhile it is to pursue. It rewards three things: higher Domain Authority, links pointing to more of your competitors, and a dofollow attribute. It subtracts points for a high spam score, and any source that already links to your domain scores 0 because that link is already won. As a rule of thumb, scores of 70 and above flag your strongest prospects, 40 to 69 are solid mid-tier targets, and anything below 40 is usually low value or spam-adjacent. This lets you skip guesswork and work down a ranked shortlist instead. After analysing, sort the Opportunities tab by score and set a minimum-score filter to surface only the prospects most likely to pay off.

Both highlight outreach prospects, but they answer different questions. Link gap shows domains that link to your competitors but not to you, so it is the action list of sites you should pitch. Common backlinks shows sources that link to two or more competitors at once, regardless of whether they link to you. A site that already references several of your rivals is statistically more likely to link to you too, which makes it a warm, high-probability prospect even before any outreach. In short, link gap answers "who am I missing," while common answers "who links across my whole niche." The tool gives each its own view mode in the Opportunities tab, plus an All view for the full picture. Toggle between Link Gap and Common to compare the two prospect lists side by side.

A dofollow link passes ranking signals (historically called PageRank) to the destination, while a nofollow link carries a rel attribute that tells search engines not to pass that authority. For link building aimed at rankings, dofollow links from relevant, authoritative domains carry the most weight, which is why the opportunity score gives dofollow sources a bonus. That said, nofollow links still bring referral traffic, brand exposure, and a natural-looking link profile, so a healthy backlink mix includes both. Chasing only dofollow links can actually look unnatural to search engines. The tool labels every source as dofollow or nofollow, shows the overall split in the Charts tab, and lets you filter the Opportunities list by link type. Use the link-type filter to focus on dofollow prospects first, then revisit nofollow sources for traffic and reach.

No. This analyzer generates realistic sample data to teach the workflow of competitive link analysis, so you can practise reading opportunity scores, filtering by Domain Authority, and spotting common linkers without paying for a database. It is a hands-on tutorial, not a live crawler, so the domains and metrics shown are illustrative rather than your competitors' actual links. When you need real referring-domain data for a live campaign, dedicated backlink databases like Ahrefs, SEMrush, and Moz pull it from their own indexes. You can still export everything here to mirror that workflow: copy a quick summary to your clipboard, download the filtered list as a CSV for a spreadsheet, or export the full report, including summaries and overlap data, as JSON. Run an analysis, apply your filters, then use the CSV or JSON button to save the results.
