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.
Core Web Vitals field data, url-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.
Field history 25 weeks
Weekly p75 from the CrUX History API, backfilled in a single request.

Main thread work
Axe violations axe-core 4.13.0, full rule set
18 violating nodes across 3 rules, 1031 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
aria-required-parent— Certain ARIA roles must be contained by particular parents 10 nodes -
serious
aria-prohibited-attr— Elements must only use permitted ARIA attributes 4 nodes -
moderate
region— All page content should be contained by landmarks 4 nodes
Accessibility failures 3 of 27 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.
-
aria-required-parent— `[role]`s are not contained by their required parent element 10 nodes -
aria-prohibited-attr— Elements use prohibited ARIA attributes 4 nodes -
target-size— Touch targets do not have sufficient size or spacing. 3 nodes
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
