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 813 ms 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

2 violating nodes across 2 rules, 142 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.

  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node
  • moderate page-has-heading-one — Page should contain a level-one heading 1 node
