Every check we run, in the open

How to read the catalog

Automated means the check's subsection has a live checker in the engine. Inside an automated subsection some checks get their own verdict and others share one subsection-level verdict (every Organization-schema check reflects whether valid Organization JSON-LD is present, for example). AI-assisted checks are scored in the Deep Audit's AI pass, which runs up to 150 of them per audit. Planned checks are specified and cataloged; their automation is still being rolled out.

A single audit scores the checks that apply to that page and the data it can reach. A check that needs input the audit doesn't have is skipped for that audit, never scored zero.

The check names, pass conditions and group headings are taken verbatim from the specification the engine loads its checks from; only headings are re-cased for reading.
