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

4 violating nodes across 4 rules, 470 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 aria-prohibited-attr — Elements must only use permitted ARIA attributes 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
  • serious scrollable-region-focusable — Scrollable region must have keyboard access 1 node

Accessibility failures 1 of 22 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.

  • aria-prohibited-attr — Elements use prohibited ARIA attributes 1 node
