Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. Not yet confirmed as a move; it needs to lead to the same place on several consecutive runs first.

Stack

Detected on the same page load as the accessibility pass — the generator from <meta name="generator"> or the shape of the page, the host from response headers.

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 3.61 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

0 violating nodes across 0 rules, 325 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.
