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 3.96 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

20 violating nodes across 6 rules, 356 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 link-in-text-block — Links must be distinguishable without relying on color 9 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 5 nodes
  • moderate region — All page content should be contained by landmarks 3 nodes
  • serious html-has-lang — <html> element must have a lang attribute 1 node
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • serious tabindex — Elements should not have tabindex greater than zero 1 node

Accessibility failures 4 of 21 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.

  • link-in-text-block — Links rely on color to be distinguishable. 9 nodes
  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 5 nodes
  • html-has-lang — `<html>` element does not have a `[lang]` attribute 1 node
  • tabindex — Some elements have a `[tabindex]` value greater than 0 1 node
