FAQ

Questions, answered

Is the audit really free?+

Yes. You get 5 full audits per day, with or without a free account. Paid plans add more audits, deeper crawls, PDF export and scheduled re-scans.

How is the score calculated?+

Each check returns pass, needs-attention or fail with a severity. Scores roll up per category using fixed weights, then into one overall score and letter grade. The weighting is documented and identical for every report, so two scans of the same site stay comparable over time.

Are the performance numbers the same as Google's?+

They are lab measurements from a headless browser, clearly labelled as such. They are a reliable diagnostic for catching regressions, but they are not the field data Google's Core Web Vitals report uses. We never present lab numbers as field data.

What does AI Search Readiness check?+

Signals that help large language models and AI search understand your site: Organization and Article schema, a llms.txt file, whether robots.txt blocks AI crawlers, and how answer-oriented your content structure is. These are readiness signals, not ranking guarantees.

How often should I re-run an audit?+

After any significant site change, and monthly as a baseline. Paid plans can schedule automatic re-scans so you can compare scores over time.
