LCP above 2.5 s

Pages whose Largest Contentful Paint is above 2.5 seconds, measured by Google PageSpeed. Critical when the number comes from real visitors (Chrome data); a warning when there is only a lab test, one simulated load on a slow phone. LCP is how long the main content takes to appear. Above 2.5 s it counts as slow in Google’s Core Web Vitals, and people leave.

CriticalPERF-003 · Performance · checked on every page

Where it usually comes from

A large hero image or slider at the top of the page, slow server response, and fonts or scripts that delay the first paint.

This check needs speed measured by Google PageSpeed. It runs only when that measurement is part of the audit; without it, the audit leaves it out rather than guess.

How to fix it

  • Find the LCP element in PageSpeed Insights — usually the main image.
  • Serve that image in a modern format at the size it is shown, and do not lazy-load it.
  • Reduce what blocks rendering before it (see PERF-002).

How to check it yourself

Run the page through PageSpeed Insights and read the Largest Contentful Paint value and the element it names.

What it looks like in a report

Critical LCP 4.1 s on mobile (limit: 2.5 s). · /

The home page hero image is the largest element and arrives late. (An example shop; the numbers are illustrative.)

How the audit counts it

PERF-003 is a critical in the performance category, and weighs heavily in that category’s score. When it appears on many pages built from the same template, the report shows it once, with the number of pages it covers — because one change in the template fixes all of them.

If the finding is deliberate on your site, it can be accepted as intentional in the report. It then leaves the list and the score, and comes back on its own if what it shows changes.

Find it on your site

A Trakis audit runs this check and the other 65 on your site, and tells you on how many pages each one sits. Or go back to all the rules.
