Frequently Asked Questions
How does this website speed test checker work?
You paste any live URL and the tool runs a real Google PageSpeed Insights test on mobile in real time, then displays your performance score and Core Web Vitals. Free AI reads those results and summarizes the highest-impact fixes in plain language. It is completely free with no signup or login required.
Is this page speed checker really free?
Yes, this page speed checker is 100% free with no signup, login, or credit card required. You can test as many URLs as you like. It fetches the live page you enter, runs a genuine PageSpeed test, shows the scores, and uses free AI to summarize what to fix, all at no cost to you.
What Core Web Vitals does the tool measure?
The tool measures the key Core Web Vitals from your speed test: Largest Contentful Paint (LCP), First Contentful Paint (FCP), Total Blocking Time (TBT), Cumulative Layout Shift (CLS), and Speed Index. Together these show how fast your page loads, how quickly it becomes interactive, and how visually stable it is on mobile devices.
Does it test mobile or desktop speed?
This checker runs the speed test on mobile, since Google uses mobile-first indexing and most visitors browse on phones. The mobile view is usually the stricter, more revealing measurement, so optimizing for it improves the experience for the majority of your audience and aligns your site with how search engines evaluate page speed.
Do I need to install anything or sign up?
No, nothing to install and no account to create. This is a browser-based tool that works instantly: enter a URL, run the test, and read your score and AI-summarized fixes. There is no signup, no login, and no software download. Just visit the page, paste your link, and get results.
What does the AI summary of fixes include?
The AI reads your PageSpeed results and produces a prioritized, plain-language list of what to fix first, ordered by impact on your score and Core Web Vitals. Instead of wading through raw technical audits, you get a clear action plan highlighting the changes most likely to make your page load faster and score higher.
Can I test any website URL with this tool?
Yes, you can test any publicly accessible URL, including your homepage, product pages, blog posts, or a competitor's page. The tool fetches whatever live URL you enter and runs the real speed test against it. Pages behind a login, password, or private network cannot be reached, since the test needs public access to load them.
Are my inputs kept private?
The URL you enter is processed server-side only to run the live speed test and generate the AI summary; it is not published or shared. Because you are typically testing public web pages, the process simply measures what any visitor's browser would load, then returns your scores and prioritized fixes privately to you.
