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

15 violating nodes across 6 rules, 159 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.

  • moderate region — All page content should be contained by landmarks 10 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 1 node
  • 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 landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • serious link-name — Links must have discernible text 1 node

Accessibility failures 4 of 19 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. 1 node
  • heading-order — Heading elements are not in a sequentially-descending order 1 node
  • link-name — Links do not have a discernible name 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
