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

36 violating nodes across 7 rules, 463 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 23 nodes
  • serious dlitem — <dt> and <dd> elements must be contained by a <dl> 6 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 3 nodes
  • minor aria-allowed-role — ARIA role should be appropriate for the element 1 node
  • serious definition-list — <dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements 1 node
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • serious link-in-text-block — Links must be distinguishable without relying on color 1 node

Accessibility failures 4 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.

  • dlitem — Definition list items are not wrapped in `<dl>` elements 6 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 3 nodes
  • definition-list — `<dl>`'s do not contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements. 1 node
  • link-in-text-block — Links rely on color to be distinguishable. 1 node
