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 3 rules, 4106 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 list — <ul> and <ol> must only directly contain <li>, <script> or <template> elements 2 nodes
  • moderate region — All page content should be contained by landmarks 2 nodes
  • moderate heading-order — Heading levels should only increase by one 1 node

Accessibility failures 2 of 19 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.

  • list — Lists do not contain only `<li>` elements and script supporting elements (`<script>` and `<template>`). 2 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 1 node

Hygiene

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