What it is
Runs Lighthouse against the page and reports its four scores: performance, accessibility, best practices and SEO. Each score comes with the individual audits behind it, so you can see exactly which checks passed and which failed.
Why it matters
A quick read on a site's technical health. The accessibility and SEO audits in particular tend to surface concrete, fixable problems rather than general advice.
