Methodology: the 77 checks

Professional and Premium audits run all 77 checks below. Each one is marked Pass, Comment (needs attention) or Not tested, with a reason. Essentials runs about 40 of the automated checks.

Tools

Lighthouse (mobile and desktop lab runs), axe-core accessibility engine, Playwright browser tests, our link crawler (every internal and external link), HTTP header and TLS inspection, sitemap and robots analysis, schema.org validation, and AI-assistant query runs (ChatGPT, Gemini, Perplexity, Claude).

Limits

We test only public pages. We never submit forms or log in. Lab speed tests can differ from real-user data. Ratings are our professional judgment based on measured evidence. This is not a legal or ADA certification.
