Lab data: Lighthouse 13.5.0 desktop run, graded above · Reproduce this run on PageSpeed Insights ↗
This Lighthouse run passes LCP, but real desktop Chrome users wait 3.8s for the largest paint. Google ranks on the real-user number.
Why is this different from the score in my browser?
The graded score is the desktop run. Lighthouse 13.5.0 runs at Google through the PageSpeed Insights API on a desktop profile with no CPU or network throttling — close to what Chrome DevTools on a laptop, GTmetrix's default test and the PageSpeed API (which defaults to desktop) all measure, so this is the number you should be able to reproduce: run it yourself on PageSpeed Insights.
Google ranks on mobile. That run happens too, on an emulated mid-range Android with a 4× CPU slowdown and a throttled connection, and the same page routinely scores 30–50 points lower there. Neither number is wrong — they are different tests.
Lighthouse also varies a few points run to run on the same URL. Treat a trend across several scans as the signal, never a single digit.
Lab data: Google PageSpeed Insights (Lighthouse, desktop). Server probes (TTFB, compression, cache, headers) are measured separately from Vilnius, Lithuania (EU).
