Metrics LAB FIELD

Core Web Vitals: failing 3 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-08-15 → 2026-09-11), url-level.

LCP Subparts LAB Throttled

The subparts attribute LCP to your server, resource discovery, download, or rendering. They come from one throttled load, the same one as the filmstrip, so they add up to that load’s LCP rather than the simulated Lab LCP above.

element render delay 4.56 s
time to first byte 584 ms

LCP LAB Simulated vs LCP FIELD

Lab 5.68 s
Field p75 2.11 s

The lab LCP is 2.69ร— the field p75 โ€” real users likely have above-average hardware or network connectivity.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

99.8% of pixels differ — they have almost nothing in common. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.

Axe violations axe-core 4.13.0, full rule set

2 violating nodes across 2 rules, 2666 passing. This is a standalone Axe CLI run and is stricter than the subset Lighthouse already includes.

  • critical aria-valid-attr-value โ€” ARIA attributes must conform to valid values 1 node
  • moderate landmark-unique โ€” Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node

Accessibility failures 2 of 34 audits

  • aria-valid-attr-value โ€” `[aria-*]` attributes do not have valid values 1 node
  • td-has-header โ€” `<td>` elements in a large `<table>` do not have table headers. 1 node

Best Practices failures 1 of 19 audits

  • valid-source-maps โ€” Missing source maps for large first-party JavaScript 178 items
