All checks
Speed / CWV · can they loaded?
Largest Contentful Paint (LCP)
How long until the biggest thing on screen — usually your hero image or headline — has finished loading. Target is under 2.5 seconds.
Why it matters
It is the moment the page feels arrived. Every extra second measurably increases the share of people who leave before seeing anything.
How to fix it, step by step
Moderate — an hour or so, or a plugin setting plus a re-check.
- 1Find what the largest element is — PageSpeed Insights names it explicitly.
- 2If it is an image: compress it, serve it as WebP, and size it correctly. A 4000px photo displayed at 800px wastes most of the download.
- 3Add fetchpriority="high" to that one image so the browser fetches it first.
- 4Remove render-blocking scripts and fonts above it — those delay everything after them.
- 5In WordPress, an image optimisation plugin plus a caching plugin covers most of this without code.
How to know it worked
PageSpeed Insights reports LCP under 2.5 seconds on mobile, which is the harder of the two.
