Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. Not yet confirmed as a move; it needs to lead to the same place on several consecutive runs first.

Stack

Detected on the same page load as the accessibility pass — the generator from <meta name="generator"> or the shape of the page, the host from response headers.

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

17 violating nodes across 4 rules, 386 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 8 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 4 nodes
  • serious link-name — Links must have discernible text 4 nodes
  • critical image-alt — Images must have alternative text 1 node

Accessibility failures 4 of 11 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
  • link-name — Links do not have a discernible name 4 nodes
  • target-size — Touch targets do not have sufficient size or spacing. 4 nodes
  • image-alt — Image elements do not have `[alt]` attributes 1 node

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