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

132 violating nodes across 6 rules, 1244 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 region — All page content should be contained by landmarks 106 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 20 nodes
  • critical button-name — Buttons must have discernible text 3 nodes
  • serious aria-dialog-name — ARIA dialog and alertdialog nodes should have an accessible name 1 node
  • serious marquee — <marquee> elements are deprecated and must not be used 1 node
  • moderate meta-viewport — Zooming and scaling must not be disabled 1 node

Accessibility failures 5 of 28 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. 20 nodes
  • button-name — Buttons do not have an accessible name 3 nodes
  • aria-dialog-name — Elements with `role="dialog"` or `role="alertdialog"` do not have accessible names. 1 node
  • frame-title — `<frame>` or `<iframe>` elements do not have a title 1 node
  • meta-viewport — `[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5. 1 node
