Website Speed Test

Measure your page load performance.

About the Site Speed Test

The Website Speed Test measures how fast any page loads and where the time goes. Get load-time metrics plus a breakdown of the likely culprits — large images, render-blocking scripts, slow servers, and uncompressed assets.

Page speed affects rankings, conversion rates, and whether crawlers — including AI bots — bother to fetch deep pages. A slow page that times out for a bot is a page that never gets cited.

Enter any URL to run the test, then fix the top issues with the Render Blocking Test, Modern Image Format Test, and GZIP Compression Test. Sign in for the full report.

Frequently asked questions

What is a good website load time?▾
Aim for the largest contentful paint under 2.5 seconds on mobile, with interaction delays under 200 milliseconds and minimal layout shift. These are Google's Core Web Vitals thresholds — the same bars AI crawlers implicitly apply when deciding what is worth fetching.
What slows down a website the most?▾
Uncompressed images, render-blocking JavaScript and CSS, slow server response, and third-party scripts are the usual suspects. A speed test identifies which of these dominates on your page so you fix the biggest lever first.
Does page speed affect SEO?▾
Yes. Core Web Vitals are a ranking signal, slow pages convert worse, and crawl budget is wasted on pages that time out. Speed is also table stakes for AI retrieval — uncrawlable pages cannot be cited.
How often should I test my site speed?▾
Test after every deploy that touches templates, scripts, or images, and run a scheduled monthly check. Performance regresses silently as teams ship features.
