Your page is slow for real visitors
Poor Lighthouse performance score
What this means
Measured on a throttled connection — the way a visitor on mobile data actually loads it — your page scores below half of what it could. On your own machine, with a fast connection and a warm cache, the same page feels instant, which is why this stays unnoticed.
Why it matters
Slow pages lose visitors before they see anything: more than half of mobile visits are abandoned when a page takes over three seconds. Loading speed also feeds directly into search ranking, so the same problem costs you traffic twice.
When this is not a problem
A single run varies with the machine that performed it. Treat the score as an order of magnitude, and re-measure before and after a change rather than chasing the exact number.
How to fix it
- Open the full Lighthouse report for the page — it lists the specific fixes ordered by how much time each one saves.
- Start with the largest contentful paint: usually a hero image without dimensions, a blocking font or a slow first response.
- Ship less JavaScript to the first screen; load the rest when it is actually needed.
- Serve images in a modern format at the size they are displayed.
The page scores poorly on Lighthouse performance. Reduce the JavaScript needed for the first screen, size and compress images properly, and remove render-blocking resources.
How to verify the fix: re-run the audit and confirm the performance score improved
