What an audit actually does
A pool of more than 100 checks across eleven segments, and the ones your site is asked depend on what kind of site it is, run against the pages your server sends. Everything here describes what we look at and how a number is arrived at, because a score you cannot take apart is a score you have to take on trust.
Your first audit is on us. Everything described here is in it. Nothing is held back for a paid tier, because a report with parts missing is not a report.
Getting started
One hop, twelve pages, and never running your JavaScript. Why that last one is the point.
The eleven categories, what each one means, and why it matters.
A score is a count. What that rules out, and what it lets you check.
