Methodology
Numbers you can stand behind.
How we measure site health, rankings, backlinks and AI citations, and what we don't claim. No black boxes: every one of the 83 checks is documented.
Site audits & crawls
When you run a free scan or audit a project, we fetch pages over HTTPS (and optionally render them with headless Chromium), then evaluate 83 technical, security, speed and AI-readiness checks defined in our check catalog. Each check lists its source and threshold.
Rank & SERP data
Rank tracking uses the locales and search engines you configure. SERP and keyword metrics may come from licensed providers; results are cached so you never pay twice for the same query.
Backlinks & the open web
Backlink counts combine our own link index (Common Crawl bootstrap plus FastRankBot) with optional licensed backlink APIs. Counts will differ from Ahrefs or Semrush because every index crawls a different slice of the web.
What we don't claim
- We don't crawl every website on the internet.
- Backlink and visibility numbers are directional, not exhaustive.
- Traffic and click estimates are models, not Google Analytics ground truth.
