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

150 violating nodes across 10 rules, 3053 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 133 nodes
serious color-contrast — Elements must meet minimum color contrast ratio thresholds 7 nodes
serious link-name — Links must have discernible text 3 nodes
minor empty-table-header — Table header text should not be empty 1 node
moderate landmark-no-duplicate-banner — Document should not have more than one banner landmark 1 node
moderate landmark-one-main — Document should have one main landmark 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
moderate page-has-heading-one — Page should contain a level-one heading 1 node
serious scrollable-region-focusable — Scrollable region must have keyboard access 1 node

Accessibility failures 5 of 30 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. 6 nodes
label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 5 nodes
link-name — Links do not have a discernible name 3 nodes
td-has-header — `<td>` elements in a large `<table>` do not have table headers. 2 nodes
landmark-one-main — Document does not have a main landmark. 1 node
