About this website speed test
This free website speed test uses Google PageSpeed Insights to measure how your homepage performs for real visitors on mobile: how fast your main content appears, how stable the layout is while it loads, and how quickly the page responds to taps and clicks. We translate the raw numbers into one plain-English verdict so you know whether speed is helping or hurting your site.
Why does my site detect a "platform"?
Most sites are built on a CMS or page builder: WordPress, Shopify, Wix, Squarespace, Webflow, and others. Your platform shapes how fast your site can be: some control the entire rendering stack and ship performance improvements to every site automatically, while others leave optimization entirely up to you. Knowing your platform tells you how much of your speed is in your hands.
How do I compare to other sites like mine?
Speed varies a lot by platform. Here is the share of sites on each platform that pass all three Core Web Vitals on mobile, based on Chrome field data. We show you where your platform's average sits, and where your site falls relative to it.

Is a website speed test the same as an SEO audit?
Speed is one input into search rankings, but it is not the whole picture. An SEO audit tool also checks your titles, meta descriptions, heading structure, internal links, and whether AI search tools like ChatGPT and Perplexity can read and cite your site. This speed test is a fast first read. The full Stackra scan covers all of it.
What's the fastest thing I can fix?
For most sites, the biggest gains come from image optimization: compressing images, converting to WebP, and reserving space for images so the page doesn't jump around while it loads. If your platform gives you little control over this, switching to a performance-focused theme or app is usually the next-best lever.
