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

3 violating nodes across 3 rules, 231 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 aria-allowed-attr — Elements must only use supported ARIA attributes 1 node
  • serious aria-prohibited-attr — Elements must only use permitted ARIA attributes 1 node
  • moderate region — All page content should be contained by landmarks 1 node
