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

19 violating nodes across 2 rules, 889 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 18 nodes
  • moderate heading-order — Heading levels should only increase by one 1 node

Accessibility failures 3 of 26 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. 21 nodes
  • target-size — Touch targets do not have sufficient size or spacing. 5 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
