Test your page speed
What does the page speed test measure?
It loads your page in Google Lighthouse and scores performance, SEO, accessibility and best practices out of 100. It also reports the Core Web Vitals that Google uses as a ranking signal, and lists the problems that cost the most loading time, largest first.
| Metric | Good | Poor |
|---|---|---|
| Largest Contentful Paint (LCP) | 2.5 s or less | over 4 s |
| Interaction to Next Paint (INP) | 200 ms or less | over 500 ms |
| Cumulative Layout Shift (CLS) | 0.1 or less | over 0.25 |
| Total Blocking Time (TBT) | 200 ms or less | over 600 ms |
How to make an online store faster
Start with images: they are usually most of a store page's weight. Then remove apps and scripts you no longer use, since each one adds blocking time. Re-test after each change to confirm the score moved.

Frequently Asked Questions
Is this page speed test free?
Yes. The test is free with no sign-up and no card, with three tests per day. It runs Google's own Lighthouse engine through the PageSpeed Insights API. The scores you see are the same kind of scores Google reports.
What is a good page speed score?
On mobile, 90 or more is good, 50 to 89 needs improvement and below 50 is poor. Mobile scores are usually lower than desktop because the test simulates a mid-range phone on a slower network. Most shoppers in Saudi Arabia browse on phones, so the mobile score matters most.
What are Core Web Vitals?
They are three measurements Google uses as a page experience signal. Largest Contentful Paint (LCP) measures how fast the main content appears and should be under 2.5 seconds. Cumulative Layout Shift (CLS) measures visual jumps and should be under 0.1. Interaction to Next Paint (INP) measures responsiveness and should be under 200 milliseconds.
Why is my score different each time I test?
Each test loads the page fresh from Google's servers, and network timing, server load and third-party scripts vary between runs. A change of a few points is normal. Look at the trend over several tests rather than a single number.
What slows down online stores the most?
Heavy product and banner images are the most common cause, followed by third-party apps and scripts that block the page while loading. Compressing images to WebP and removing unused apps usually give the biggest gains. You can compress images for free with our image compressor.
