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 8 rules, 475 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 4 nodes
  • critical aria-valid-attr-value — ARIA attributes must conform to valid values 2 nodes
  • critical image-alt — Images must have alternative text 2 nodes
  • minor image-redundant-alt — Alternative text of images should not be repeated as text 2 nodes
  • serious tabindex — Elements should not have tabindex greater than zero 2 nodes
  • serious link-name — Links must have discernible text 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 5 of 27 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. 5 nodes
  • aria-valid-attr-value — `[aria-*]` attributes do not have valid values 2 nodes
  • image-alt — Image elements do not have `[alt]` attributes 2 nodes
  • tabindex — Some elements have a `[tabindex]` value greater than 0 2 nodes
  • link-name — Links do not have a discernible name 1 node
