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

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

Metrics LAB

No field data: the Chrome UX Report is not being collected for this project, so every figure below is from the Lighthouse run.

LCP Subparts LAB Unthrottled

The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

0% of pixels differ — they are identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
