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

47 violating nodes across 2 rules, 269 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 46 nodes
  • moderate landmark-one-main — Document should have one main landmark 1 node

Accessibility failures 1 of 16 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.

  • landmark-one-main — Document does not have a main landmark. 1 node

Hygiene

Changes rarely — which is exactly why a change is worth noticing.
