Free PageSpeed Insights Tool: Find Out Why Your Site Is Slow (And How to Fix It)
PageSpeed Insights is a performance testing system created by Google.
It uses Lighthouse to analyze how fast a page loads, how stable it feels, and how responsive it is for users.
This tool runs the same type of checks Google uses to evaluate real websites.
That means your results reflect important ranking signals, including Core Web Vitals, for both mobile and desktop.
If your site feels slow to users, Google usually sees it the same way.
Your Site Is Losing Visitors (And You May Not Notice)
When a page loads slowly, many visitors leave before it finishes. This happens more frequently on mobile devices, where connections are weaker and devices are slower. Drop your URL below and check what’s slowing your site down. The scan takes about 30 seconds.

Speed Matters More Than You Think
Someone clicks your link and waits. If the page feels slow or unresponsive, they often leave without reading anything. Slow pages can increase bounce rates and reduce conversions. Google tracks how users interact with pages, and performance plays a role in how sites are ranked. Faster pages usually provide a better user experience. A better experience often leads to stronger rankings over time. This tool shows what’s affecting your speed so you can fix real problems instead of guessing.
What This Tool Actually Does
Enter your website address, and the tool scans it using Google Lighthouse standards.
You’ll get:
A mobile performance score, A desktop performance score. Scores range from 0 to 100. Higher is better. More importantly, you’ll see Core Web Vitals, which Google uses as part of its page experience system.
Key Metrics to Track
Metric | Full Name | What it Measures |
LCP | Largest Contentful Paint | How fast does the main content appears |
INP | Interaction with Next Paint | How responsive the page feels when users interact |
CLS | Cumulative Layout Shift | Whether the layout “jumps” while loading |
Improving these metrics helps your site feel faster and more stable for real users.
How Google Measures Page Speed (Important to Understand)
The test is based on Google Lighthouse, the same open-source tool Google uses for performance analysis. Lighthouse is maintained by Google and widely used by developers and SEO professionals to measure performance and user experience.
PageSpeed Insights uses lab data, not live visitor data.
That means:
Your site is tested in a controlled environment. A simulated mobile device and network are used. Results are consistent but not identical every time. This is why scores can change slightly between tests. Small variations are normal. For best accuracy, run multiple tests and focus on patterns, not single numbers.
Mobile vs Desktop Speed (The Real Difference)
Your desktop score might look good. Your mobile score might not.
This happens because phones have:
Slower processors Smaller memory, and less stable network connections. Large images, heavy scripts, and animations affect mobile devices much more than desktops. Most users browse on phones. Google also evaluates sites using mobile-first indexing. If your mobile score is weak, your desktop score won’t save you.
Fixes That Actually Improve Speed
Not all fixes matter equally.
Start with changes that affect Core Web Vitals first. These usually deliver the biggest gains.
01.
Optimize Images
Large images slow pages more than anything else. Compress images and use modern formats like WebP. This alone can noticeably reduce load time.
02.
Enable Browser Caching
Caching allows returning visitors to load pages faster. Their browser reuses saved files instead of downloading everything again.
03.
Remove Unused Code
Unused plugins, scripts, and styles add weight.
If it doesn’t serve a purpose, remove it.
04.
Improve Hosting Quality
Slow servers delay everything.
Cheap hosting often causes poor server response times, especially during traffic spikes.
05.
Use a CDN
A CDN stores copies of your site on servers around the world.
Visitors load your site from the nearest location instead of one distant server.
06.
Reduce Server Response Time
Clean databases, optimized code, and proper caching help servers respond faster. Aim for a server response time under 200 milliseconds.
Real Example (What Usually Happens)
A typical WordPress site with a mobile score around 40 often improves to 70+ after:
- Compressing images
- Removing unused plugins
- Enabling caching
No redesign required. Just cleanup and optimization.
What Your PageSpeed Score Means
Here’s a simple way to read your score:
90–100: Excellent performance
50–89: Fixable issues holding you back
0–49: Serious performance problems
You don’t need a perfect 100. Anything above 85 already beats most websites. Focus on red and orange warnings first. They usually deliver the biggest improvements.
Any Questions?*
Yes. Page speed is a confirmed ranking factor. Core Web Vitals are part of Google’s page experience system. Speed alone won’t rank a site, but slow performance can limit rankings.
A score above 85 is strong. Scores between 50 and 89 usually need optimization. Below 50 indicates serious issues.
Start with image optimization, caching, and removing unused code. These changes often lead to noticeable improvements.
Tests use simulated environments. Network conditions and server load can vary. Small score changes are normal.
At least once a month. Always test after adding plugins, changing themes, or updating major content.
Mobile is more important. Google evaluates sites using mobile-first indexing, and most traffic comes from phones.
Your Competitors Are Already Improving Their Speed
Faster sites usually win more clicks and hold rankings better.
If your site feels slow, it’s time to fix it.
