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 observed, unthrottled

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 5.25 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Axe violations axe-core 4.13.0, full rule set

154 violating nodes across 8 rules, 1261 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 color-contrast — Elements must meet minimum color contrast ratio thresholds 108 nodes
  • moderate region — All page content should be contained by landmarks 24 nodes
  • serious link-name — Links must have discernible text 8 nodes
  • serious link-in-text-block — Links must be distinguishable without relying on color 6 nodes
  • moderate heading-order — Heading levels should only increase by one 3 nodes
  • critical button-name — Buttons must have discernible text 2 nodes
  • moderate landmark-one-main — Document should have one main landmark 2 nodes
  • serious accesskeys — accesskey attribute value should be unique 1 node

Accessibility failures 7 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.

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 108 nodes
  • link-name — Links do not have a discernible name 9 nodes
  • target-size — Touch targets do not have sufficient size or spacing. 8 nodes
  • link-in-text-block — Links rely on color to be distinguishable. 6 nodes
  • heading-order — Heading elements are not in a sequentially-descending order 3 nodes
  • button-name — Buttons do not have an accessible name 2 nodes
  • accesskeys — `[accesskey]` values are not unique 1 node
