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

3 violating nodes across 2 rules, 622 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.

  • serious link-in-text-block — Links must be distinguishable without relying on color 2 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 1 node

Accessibility failures 2 of 25 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.

  • link-in-text-block — Links rely on color to be distinguishable. 2 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 1 node
