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 1.06 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.

time to first byte 89 ms
element render delay 70 ms

Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 548 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 1 of 28 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.

  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 2 nodes
