What LCP is made of

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Axe violations axe-core 4.13.0, full rule set

4 violating nodes across 4 rules, 5 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.

  • serious html-has-lang — <html> element must have a lang attribute 1 node
  • moderate landmark-one-main — Document should have one main landmark 1 node
  • moderate page-has-heading-one — Page should contain a level-one heading 1 node
  • moderate region — All page content should be contained by landmarks 1 node

Accessibility failures 2 of 6 audits

Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.

  • html-has-lang — `<html>` element does not have a `[lang]` attribute 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
