Website Speed Test

The Website Speed Test is a free tool that fetches any public page live and measures the factors that actually determine how fast a real visitor experiences it — server response time, total page weight, the number of requests the page makes, and whether compression and caching are enabled. Instead of a vague "fast" or "slow" verdict, you get concrete, measured numbers on each factor, plus a clear explanation of exactly what's dragging the page down and how to fix it.

It exists because speed problems are rarely obvious just from browsing a site yourself — a page can feel fine on a fast connection and a warm cache while still being genuinely slow for a first-time visitor on mobile data. Running a test surfaces the underlying numbers directly: an uncompressed response, an unusually high request count, or a server that's slow to even start responding. It works on any public page, which makes it just as useful for benchmarking a competitor as it is for auditing your own site.

When you submit a URL, the tool fetches the page live and times how long the server takes to respond, reads the actual transferred byte size and HTTP response headers, and parses the HTML to count external scripts, stylesheets, and other requests the page will trigger. Compression is confirmed directly from the Content-Encoding header rather than assumed, and each of these measurements feeds into the score and the specific list of issues shown in your report.

This reflects a single live fetch of the page at the moment you run the test, from our server rather than a real visitor's device or location, so results can vary somewhat from what a visitor on a different connection or region would experience. It measures the initial HTML response rather than full browser rendering, so it won't capture rendering-time factors like JavaScript execution cost the way a full browser-based test would.

• Aim for a server response time under roughly 800ms. Faster response times keep visitors from bouncing before the page even starts rendering, which matters more than almost any other single speed metric.
• Enable gzip or Brotli compression on your server. It can shrink text-based transfer size by 60-80% with zero visual change to the page, making it one of the highest-impact, lowest-effort speed fixes available.
• Set explicit width and height attributes on every image. Without them, the browser doesn't know how much space an image will take until it loads, which causes the page to visibly jump around as images pop in.
• Trim the number of requests a page makes. Every extra script, stylesheet, or font file is another round trip the browser has to complete before the page becomes usable, and those add up fast on media-heavy pages.
