Guides
Each of these explains one part of the job properly - what to check, in what order, what each fix actually breaks, and where the honest answer is that no external tool can tell you. Written to be useful whether or not you ever run a scan with us.
Cites a check from 7 of the 9 categories, which is what a guide about the whole job looks like in the data.
Method
What to check on a website and in what order: what decides whether it is secure, fast, indexable and usable - and the questions no external scan can answer.

Where these come from
Every guide names the specific checks in our engine that correspond to what it explains - 199 checks across 9 categories - so you can match a line in a report to the reason it is there. Nothing here describes a check the engine does not run.
