What does PageSpeed AI Auditor check?
PageSpeed AI Auditor runs a mobile Google PageSpeed Insights test and turns the important data into a clear report. Instead of leaving you with a technical dashboard alone, it helps you decide what is worth fixing first on a business website, landing page or online shop.
The audit shows performance, basic SEO and accessibility scores, together with loading metrics and opportunities found by Lighthouse. It is a practical starting point for checking whether your website helps a visitor move from the first visit to an enquiry, booking or purchase.
In one report
The areas covered by your website performance test
Every part of the report answers a different question about the mobile visitor experience.
Mobile performance
See whether important content appears quickly and whether images or scripts slow down the first impression.
Core Web Vitals
Understand LCP and CLS: the speed of the main content and how stable the layout stays as it loads.
SEO and accessibility
Review technical visibility foundations and how easy the page is for different visitors to use.
Improvement priorities
Get a concise list of the issues with the greatest likely impact instead of interpreting Lighthouse output on your own.
Understanding the result
How to read PageSpeed and Core Web Vitals results
A single score does not describe the whole experience. Use the score, metrics and opportunities together.
| Metric | What it means | What to look for |
|---|---|---|
| FCP | The first visible piece of content. | Can a visitor quickly see that the page has started to load? |
| LCP | When the main first-view content appears. | Large images, the hero section, server response and blocking resources can delay it. |
| CLS | Unexpected layout movement while loading. | Moving buttons or text reduce confidence and can lead to mistaps. |
| TBT | Time when scripts block responsiveness in the lab test. | Too much JavaScript can delay clicks, scrolling and interactions. |
After the audit
Where to start when a website is slow
Not every message needs the same attention. Start with the things visitors see or feel first.
Reduce the weight of the first view
Optimise the main image, image format and files loaded before the first content appears.
Delay code that is not needed immediately
Plugins, analytics, adverts and third-party widgets can often load later or only on the pages where they are useful.
Keep the layout stable
Give images and embedded elements predictable dimensions so that they do not push buttons and content around while the page loads.
Test again on mobile
After each meaningful change, run another test and compare the metric you intended to improve, not just the overall score.
Common questions
FAQ: website speed tests and PageSpeed Insights
Answers to help you use the audit before and after website optimisation.
Is this website speed test free?
Yes. Enter a public website address and the tool runs a free mobile test. There is no account or sign-up required.
Do I need a 100/100 PageSpeed score?
No. A perfect score is not the goal. The important thing is that key content appears quickly, the page stays stable and visitors can use it comfortably on a mobile phone. The audit helps you prioritise practical improvements rather than chase one number.
Why can my PageSpeed score change between tests?
A laboratory test runs in controlled conditions, but results can still vary because of server load, third-party resources and network conditions. Compare the trend across several tests, especially after a change, rather than relying on one result.
What is the difference between lab data and real-user data?
Lab data simulates a visit and is useful for finding specific technical problems. Real-user data reflects actual visitors. A new or low-traffic website may not yet have enough real-user samples for Google to show them.
Does website speed affect SEO?
Speed does not replace useful content, a clear offer or good page structure. It does, however, affect the experience visitors have when they land on a page, especially on mobile, and a slow or unstable page can make it harder for them to take the next step.
What should I fix first on a slow website?
Start with the issues in the report that have the biggest visitor impact: heavy images, unused JavaScript, a slow hero section and resources that delay the first view. Test again after each meaningful change.
