What is the Web Page Speed Test?

The Web Page Speed Test uses the Google PageSpeed Insights API to analyse the loading speed of any webpage — for mobile and desktop separately. It provides a score of 0–100 and detailed Core Web Vitals metrics that Google uses for ranking.

What are Core Web Vitals?

Core Web Vitals are three metrics that Google considers critical for user experience:

LCP (Largest Contentful Paint): How quickly the largest element on the page loads. Target: < 2.5 seconds.
FID / INP (Interaction to Next Paint): How quickly the page responds to clicks. Target: < 200ms.
CLS (Cumulative Layout Shift): How much the layout "shifts" during loading. Target: < 0.1.

Why is it important for SEO?

Since 2021, Google has used Core Web Vitals as a ranking factor (Page Experience Update). Pages with good vitals can gain positions over comparable pages with poor performance. Additionally, faster pages have lower bounce rates and higher conversion rates.

Mobile vs Desktop — which should I test?

Google uses mobile-first indexing, meaning it evaluates your mobile version first. Always start with the mobile test. If the mobile score is below 50, this affects your ranking regardless of the desktop score.

How can I improve my score?

Use modern image formats (WebP, AVIF).
Enable lazy loading for images outside the viewport.
Minify CSS, JS, and HTML.
Use a CDN for static assets.
Enable server-side caching and GZIP/Brotli compression.

Frequently Asked Questions

What does a score of 90+ mean, and what does a score below 50 mean?

Score 90–100 = Green / Excellent. 50–89 = Orange / Needs improvement. Below 50 = Red / Poor — the page loads slowly and you are likely losing rankings and conversions.

Why does my score change every time I run the test?

PageSpeed Insights uses real-world data from the Chrome User Experience Report (CrUX) as well as lab measurements that depend on network load at that moment. Small fluctuations of ±5 points are normal.

Do I need a score of 100 for good SEO?

No. Even large sites like Wikipedia or Amazon don't score 100. Aim for above 80 on mobile and above 90 on desktop. The most important improvement is moving from red to orange.
