Honest data

What our tools measure — and what they don’t

Our checks read your live pages and use Google’s PageSpeed Insights. We don’t show Domain Authority, backlink counts or traffic estimates: those come from proprietary indexes (Moz, Ahrefs, Semrush) and we won’t invent them. Our team uses licensed data for those in paid audits.

Measured on your site

Titles, meta, headings, canonicals, robots.txt, sitemaps, links, images, schema, HTTPS, headers, AI crawler access.

From Google

Lighthouse performance and Core Web Vitals, from real Chrome users when available.

Written by AI, grounded in data

The audit summary and 30-day plan are generated only from the checks in your report.
