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

63 violating nodes across 7 rules, 456 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 color-contrast — Elements must meet minimum color contrast ratio thresholds 46 nodes
  • critical image-alt — Images must have alternative text 8 nodes
  • serious link-in-text-block — Links must be distinguishable without relying on color 5 nodes
  • moderate heading-order — Heading levels should only increase by one 1 node
  • moderate landmark-one-main — Document should have one main landmark 1 node
  • moderate meta-viewport — Zooming and scaling must not be disabled 1 node
  • moderate region — All page content should be contained by landmarks 1 node

Accessibility failures 6 of 16 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.

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 46 nodes
  • image-alt — Image elements do not have `[alt]` attributes 8 nodes
  • link-in-text-block — Links rely on color to be distinguishable. 5 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
  • meta-viewport — `[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5. 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
