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

152 violating nodes across 6 rules, 1981 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 127 nodes
  • moderate region — All page content should be contained by landmarks 19 nodes
  • critical image-alt — Images must have alternative text 2 nodes
  • serious link-name — Links must have discernible text 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

Accessibility failures 7 of 21 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. 7 nodes
  • image-alt — Image elements do not have `[alt]` attributes 2 nodes
  • link-name — Links do not have a discernible name 2 nodes
  • button-name — Buttons do not have an accessible name 1 node
  • frame-title — `<frame>` or `<iframe>` elements do not have a title 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
