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

29 violating nodes across 5 rules, 477 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 17 nodes
  • moderate region — All page content should be contained by landmarks 7 nodes
  • serious listitem — <li> elements must be contained in a <ul> or <ol> 3 nodes
  • serious document-title — Documents must have <title> element to aid in navigation 1 node
  • moderate landmark-one-main — Document should have one main landmark 1 node

Accessibility failures 4 of 15 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 17 nodes
  • listitem — List items (`<li>`) are not contained within `<ul>`, `<ol>` or `<menu>` parent elements. 3 nodes
  • document-title — Document doesn't have a `<title>` element 1 node
  • landmark-one-main — Document does not have a main landmark. 1 node
