What is a Website Speed Test?
A Website Speed Test measures how quickly your webpage loads and responds, evaluating factors like Core Web Vitals across both desktop and mobile conditions.
Our free Website Speed Test provides a detailed performance report, helping you identify what's slowing your site down and how to fix it.
Page speed is measured differently than most people assume: a "speed test" isn't a single number but a composite of several distinct metrics, each capturing a different aspect of how a page loads and responds. Core Web Vitals, Google's specific set of user-experience metrics, measure loading speed, interactivity, and visual stability separately, since a page can excel at one of these while genuinely struggling at another.
Our Website Speed Test analyzes your page across both desktop and mobile conditions, since these often produce meaningfully different results, mobile speed carries more weight for SEO overall, because Google primarily uses the mobile version of your site for ranking through what's called mobile-first indexing. A score of 90 or above on the standard 0-100 scale is generally considered strong performance, while scores below 50 usually point to real, worth-investigating problems, most commonly large unoptimized images, excessive JavaScript, or slow server response times.
It's normal to see your score fluctuate slightly between individual test runs, even without changing anything on your site. Lab-based speed tests run on a simulated connection under standardized conditions each time, so minor variation in server response and network simulation between runs is expected and not a sign of a fundamental problem. It's also possible for your site to feel fast when you personally browse it while still scoring poorly in a formal test, since your own device and connection may simply be faster than a meaningful portion of your actual visitors' setups.
