Frequently asked questions
If you cannot find what you need write to us — we usually reply the same day.
Are the tools really free?
Yes. All 26 tools are free to use and no sign-up is required to run an analysis. A free account only lets you keep your report history and generate shareable links.
How is the SEO Health Score calculated?
The score is a weighted average of 7 categories: technical SEO, on-page, content and E-E-A-T, performance, structured data, crawlability and GEO/AI readiness. Each category scores 0–100 from its own check set; weights reflect real impact on search rankings.
Is the Core Web Vitals data real or estimated?
Real. LCP, INP and CLS come from the Google PageSpeed Insights API, using CrUX field data (real user measurements) where available. Pages without field data show lab (Lighthouse) results, clearly labelled as such.
What does GEO / AI search readiness mean?
Generative Engine Optimization measures how citable your content is for generative search engines such as Google AI Overviews, ChatGPT and Perplexity. The tool checks clear definition blocks, citable data, structured data coverage, AI crawler access permissions and the presence of llms.txt.
How many pages can the Site Crawler handle?
The crawler follows links across your site and shows live progress while it runs. It reports broken links, redirect chains, duplicate titles and descriptions, missing meta tags and orphan pages. For large sites you can set the crawl limit before starting.
Is the data I analyze stored?
Analyses fetch and parse pages server-side. Analyses you run without signing in are not saved to an account; they are only kept in a short-lived cache. See the Privacy Policy for details.
