This URL redirects to https://creativedesignsguru.com/demo/Eleventy-Starter-Boilerplate/.

A trailing slash only, so both forms are treated as one site rather than two — one history, measured once. Lighthouse follows the redirect, so the numbers below describe the canonical page; the only cost is an extra hop on each run.

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.

Core Web Vitals field data, origin-level

Real Chrome users, 28-day window (2026-07-19 → 2026-08-15). From the backfilled CrUX history rather than this measurement, which predates the API key. This is what Google measures you on.

What LCP is made of

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

element render delay 47 ms

Axe violations axe-core 4.13.0, full rule set

4 violating nodes across 2 rules, 88 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 region — All page content should be contained by landmarks 3 nodes
  • moderate landmark-one-main — Document should have one main landmark 1 node

Accessibility failures 1 of 20 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.

  • landmark-one-main — Document does not have a main landmark. 1 node
