Topical Alignment & Link Risk Checker
Enter your site and a prospective collaboration partner -- as a domain or just a short niche description -- and see how closely aligned your topics really are before you exchange links.
Why topical relevance matters for backlinks
Search engines don't just count links -- they look at context. A link from a site that covers roughly the same subject as yours reads as a natural, editorial reference. A link from a completely unrelated site -- a finance blog linking to a pet grooming site, say -- is one of the clearest signals of a paid or reciprocal link scheme rather than a genuine recommendation.
How the alignment score works
Enter a domain and this tool fetches its homepage and pulls out the words that actually describe what it's about, filtering out filler words and site boilerplate. If you'd rather not have your own site fetched, or you're evaluating a niche rather than a specific site, you can just describe it in a few words instead. The two keyword sets are then compared: the more they overlap, the higher the alignment score.
What counts as a risky link exchange
Reciprocal link exchanges and guest posts aren't inherently against the rules -- what search engines penalize is links that exist purely to manipulate rankings, disconnected from any real topical or editorial relationship. A low alignment score here doesn't mean a collaboration is impossible, just that it's worth asking why the two sites would genuinely reference each other before you exchange links.
A safer way to find aligned partners
Instead of cold-emailing sites and hoping for a topical fit, PressCircle matches verified members strictly within their own vertical. Every profile is DNS-verified and every match is opt-in on both sides, so the collaborations you find are already the kind of genuine, on-topic connection this tool is checking for.
Frequently asked questions
Do I need a website, or can I just describe my niche?
Either works. Enter a domain and the tool fetches and analyzes its homepage automatically, or describe your niche -- or your prospective partner's -- in a few words instead.
What counts as a good topical alignment score?
Higher overlap between the two keyword sets means a more natural, editorially justifiable connection. A low score doesn't make a collaboration impossible, but it's worth asking why the two sites would genuinely reference each other.
