What Is a Website Speed Test and Why It Matters
A website speed test checks how quickly a page loads and highlights the signals that can slow it down. That matters because slow pages can frustrate visitors, increase bounce rates, and make a site feel harder to use on mobile.
What a website speed test measures
A speed test usually looks at loading time, responsiveness, and layout stability. That is why reports often mention values such as FCP, LCP, TBT, and CLS.
Why website speed matters
Faster pages are easier to use, especially on phones and slower connections. They also make it easier for visitors to stay on the page and complete what they came to do.
If mobile experience is also a concern, the Mobile Friendly Checker is a helpful next step.
How to use a speed test report well
A good report is not just a score. It should help you see which page needs attention and which loading signals may need improvement.
Start with the Website Speed Test to review the page, then use related site checks if you want more context.
Useful tools to check next
After a speed test, you may also want to try the Mobile Friendly Checker, Website Screenshot Tool, or DNS Lookup depending on what you want to inspect.
