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

54 violating nodes across 4 rules, 1596 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.

  • critical image-alt — Images must have alternative text 37 nodes
  • serious link-name — Links must have discernible text 15 nodes
  • minor aria-allowed-role — ARIA role should be appropriate for the element 1 node
  • moderate region — All page content should be contained by landmarks 1 node

Accessibility failures 3 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.

  • image-alt — Image elements do not have `[alt]` attributes 37 nodes
  • link-name — Links do not have a discernible name 15 nodes
  • target-size — Touch targets do not have sufficient size or spacing. 7 nodes
