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

11 violating nodes across 3 rules, 125 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.

  • moderate region — All page content should be contained by landmarks 9 nodes
  • moderate landmark-one-main — Document should have one main landmark 1 node
  • serious link-in-text-block — Links must be distinguishable without relying on color 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.

  • aria-prohibited-attr — Elements use prohibited ARIA attributes 1 node
  • link-in-text-block — Links rely on color to be distinguishable. 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
