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 6.66 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.

resource load delay 612 ms
element render delay 118 ms
resource load duration 87 ms
time to first byte 10 ms

Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 2290 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.

Accessibility failures 3 of 35 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. 1 node
  • target-size — Touch targets do not have sufficient size or spacing. 1 node
  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 1 node

Hygiene
