The guide

What the page speed checker does, how to use it, and what to do with the result.

A page speed checker measures how quickly a page loads and becomes usable for real visitors. You enter a URL and it reports a mobile performance score with timing metrics like time to first byte, First Contentful Paint and Speed Index, then highlights what is slowing the page down. It turns a vague sense that a page feels slow into specific numbers and clear opportunities to fix.

What the page speed checker measures

The checker loads your page and records the timeline from the first request to a fully usable view. It captures server response time, when the first content paints, when the largest element renders, and how long until the page responds to input. It also breaks down page weight by resource type, showing how much images, scripts, stylesheets, and fonts each contribute. Render-blocking files, oversized images, and long-running scripts are surfaced as concrete bottlenecks. Instead of a single score, you get a clear picture of where the milliseconds go, so you know which asset or request to tackle first for the biggest gain.

How to improve a slow page speed score

Start with the heaviest contributors the report names. Compress and correctly size images, and serve modern formats to shrink the largest payloads. Defer or remove render-blocking scripts and stylesheets so content paints sooner, and minify what remains. Improve server response time with caching and a content delivery network so the first byte arrives quickly. Preload critical assets like your hero image and primary font, and lazy-load anything below the fold. Reduce third-party scripts that add weight and delay interactivity. Recheck after each change and compare timings, since fixing one bottleneck often reveals the next one that now limits how fast the page feels.

Page speed benchmarks and when to test

Aim to keep the largest content rendering within a couple of seconds and interactivity ready shortly after, since visitors abandon pages that stall. Test after every significant change: new templates, added scripts, redesigned pages, or a fresh batch of images can all quietly erode speed. Check key landing pages and templates rather than a single URL, because one slow shared component can drag down many pages. Compare mobile and desktop, as phones on slower networks feel delays first. Regular testing catches regressions early and keeps performance from decaying gradually until it starts costing you rankings and conversions.
