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

5 violating nodes across 2 rules, 363 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 image-alt — Images must have alternative text 4 nodes
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node

Accessibility failures 1 of 20 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.

  • image-alt — Image elements do not have `[alt]` attributes 4 nodes

Hygiene

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