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 34.93 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.

element render delay 5.05 s
resource load delay 224 ms
time to first byte 223 ms
resource load duration 12 ms

Accessibility failures 2 of 32 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-prohibited-attr — Elements use prohibited ARIA attributes 2 nodes
  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 2 nodes
