Core Web Vitals field data, origin-level

Real Chrome users, 28-day window (2026-07-19 → 2026-08-15). From the backfilled CrUX history rather than this measurement, which predates the API key. This is what Google measures you on.

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.

element render delay 94 ms
time to first byte 41 ms

Field history 25 weeks

Weekly p75 from the CrUX History API, backfilled in a single request.

Axe violations axe-core 4.13.0, full rule set

7 violating nodes across 3 rules, 161 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 5 nodes
  • moderate page-has-heading-one — Page should contain a level-one heading 1 node
  • moderate region — All page content should be contained by landmarks 1 node

Accessibility failures 1 of 22 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. 5 nodes

Hygiene

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