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, 418 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 frame-title — Frames must have an accessible name 2 nodes
  • serious aria-hidden-focus — ARIA hidden element must not be focusable or contain focusable elements 1 node

Accessibility failures 2 of 24 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.

  • frame-title — `<frame>` or `<iframe>` elements do not have a title 2 nodes
  • aria-hidden-focus — `[aria-hidden="true"]` elements contain focusable descendents 1 node

Hygiene

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