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

1 violating node across 1 rule, 69 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 meta-refresh — Delayed refresh under 20 hours must not be used 1 node

Accessibility failures 3 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.

  • heading-order — Heading elements are not in a sequentially-descending order 1 node
  • skip-link — Skip links are not focusable. 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
