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

10 violating nodes across 6 rules, 497 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.

  • critical image-alt — Images must have alternative text 4 nodes
  • moderate page-has-heading-one — Page should contain a level-one heading 2 nodes
  • serious frame-title — Frames must have an accessible name 1 node
  • moderate heading-order — Heading levels should only increase by one 1 node
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • moderate region — All page content should be contained by landmarks 1 node

Accessibility failures 3 of 15 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.

  • image-alt — Image elements do not have `[alt]` attributes 4 nodes
  • frame-title — `<frame>` or `<iframe>` elements do not have a title 1 node
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
