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 3 rules, 2046 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 landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 2 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 1 node
  • moderate landmark-no-duplicate-contentinfo — Document should not have more than one contentinfo landmark 1 node

Accessibility failures 1 of 26 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.

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 1 node
