How the match score works

Each match is a 0–100 similarity score — the higher it is, the more two sites resemble one another. It’s computed automatically from our own crawl data (never from what a site says about itself) by combining several independent signals, so a high score means several of them point the same way:

• co-citations how often the same third-party websites link out to both — sites referenced together tend to serve the same world.
• shared tech how much of their technology stack (CMS, e‑commerce, analytics, frameworks…) overlaps.
• shared category whether they sit in the same business / industry category.
• positioning how closely their titles and on‑page wording line up.

No single signal decides the result — they’re blended together. Treat the score as a way to rank candidates rather than an absolute percentage; the chips on each result show which signals contributed.
