Is your website loading slowly? A slow website can frustrate visitors and make it harder for them to explore your content. However, before changing your website design or installing optimization plugins, you need to understand what is causing the problem.
Google PageSpeed Insights is a free tool that helps you test website performance and identify possible improvements. It provides performance reports for mobile and desktop devices, along with recommendations to help your pages load and respond more efficiently.
You do not need coding skills to get started. In this guide, you will learn how to use Google PageSpeed Insights, understand its results, and apply practical improvements to your website.
What Is Google PageSpeed Insights?
Google PageSpeed Insights is a free website performance testing tool. It analyzes a web page and provides information about its loading speed, responsiveness, visual stability, and other performance factors.
The tool uses two types of data when available:
Field data: Information collected from real users who visit your website through the Chrome User Experience Report.
Lab data: A controlled test that analyzes your page under simulated conditions.
These reports help you understand how a page performs in real-world situations and identify potential technical issues.
For example, your homepage might load quickly on your computer but perform poorly on a mobile device. Testing both versions can help you discover problems that need attention.
Why Should You Test Your Website With PageSpeed Insights?
Regular website testing helps you understand whether your pages provide a smooth browsing experience.
Here are some benefits of using the tool.
1. Identify Website Performance Problems
The report highlights possible problems related to images, scripts, page loading, and other technical factors. This gives you a starting point for website optimization.
2. Check Mobile and Desktop Performance
Mobile and desktop reports can reveal different performance issues. A page may perform well on a desktop computer but need improvements for smartphone users.
3. Understand Core Web Vitals
PageSpeed Insights helps you review important user experience metrics, including loading performance, responsiveness, and visual stability.
4. Get Actionable Recommendations
The tool provides suggestions that can help you identify opportunities to improve your website. Some changes are simple, while others may require technical assistance.
You can use these findings as part of your broader website speed optimization strategy.
How to Use Google PageSpeed Insights Step by Step
Follow these steps to test your website.
Step 1: Open Google PageSpeed Insights
Visit the official tool at pagespeed.web.dev.
You will find a field where you can enter a website URL.
Step 2: Enter Your Website URL
Copy the URL of the page you want to test and paste it into the field.
For example, you can test your homepage:
https://mehfuzasultana.com/
You can also test an individual blog post. Testing specific pages is useful because different pages may contain different images, layouts, plugins, and scripts.
Click Analyze to start the test.
Step 3: Review the Mobile Report
PageSpeed Insights usually displays the mobile report first when you run an analysis.
Review the performance score and the information below it. Pay attention to issues that may affect loading time or make the page difficult to use.
Mobile performance is important because many visitors browse websites using smartphones.
However, do not assume that every low score requires an immediate technical overhaul. Review the recommendations and identify the problems with the greatest potential impact.
Step 4: Check the Desktop Report
Switch to the desktop report to see how your page performs on desktop devices.
Compare the two reports. If mobile performance is much weaker, investigate image sizes, scripts, responsive layouts, and server performance.
Remember that mobile and desktop tests use different simulated conditions. Their scores may differ even when you have not changed your website.
Step 5: Review the Performance Score
The Performance score ranges from 0 to 100.
Google PageSpeed Insights generally groups scores into these categories:
90–100: Good
50–89: Needs improvement
0–49: Poor
Use these categories as a guide, not as the only measure of success. Your website should also load reliably, display correctly, and respond smoothly to visitors.
Step 6: Read the Recommendations
Scroll down to the diagnostics and opportunities shown in the report.
Depending on your page, you may see recommendations related to image delivery, render-blocking resources, JavaScript, caching, or other performance issues.
Start with the recommendations you understand. If a suggestion requires changing code or server settings, make a backup or ask a developer for help.
Understanding the Main PageSpeed Insights Metrics
To use the report effectively, you should understand the key performance metrics.
Largest Contentful Paint (LCP)
Largest Contentful Paint measures how quickly the main content of a page becomes visible.
A good LCP result is 2.5 seconds or less.
Large hero images, slow server responses, and delayed resource loading can affect this metric.
To improve LCP, investigate the main image, server response time, and resources needed to display the largest visible content.
Interaction to Next Paint (INP)
Interaction to Next Paint measures how quickly a page responds visually to user interactions.
A good INP result is 200 milliseconds or less.
Heavy JavaScript and long-running browser tasks can affect responsiveness. If your report highlights interaction problems, you may need to reduce unnecessary scripts or optimize complex page elements.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift measures unexpected movement of page elements while a page loads.
A good CLS result is 0.1 or less.
For example, an image without reserved space may cause text to move when the image appears. Advertisements or dynamically inserted elements can also contribute to layout shifts.
To reduce these problems, specify image dimensions and reserve suitable space for elements that load later.
How to Fix Common PageSpeed Insights Problems
After testing your website, you can start working on the most relevant recommendations.
1. Optimize Large Images
Large images can increase page loading time. Resize them to suitable dimensions and compress them before uploading.
Consider using WebP when appropriate. Also, avoid loading unnecessarily large images on mobile devices.
For a blog, start with the featured images and other large visuals that appear near the top of the page.
2. Reduce Unnecessary Plugins
If you use WordPress, review your installed plugins.
Remove plugins that are no longer needed and avoid using multiple plugins for the same purpose. However, remember that plugin count alone does not determine website speed.
Test your website after removing or changing plugins to make sure important features still work.
3. Enable Suitable Caching
Caching can reduce the work required to generate a page for each visitor.
Check whether your hosting provider offers built-in caching. If you use a WordPress caching plugin, follow the instructions for your hosting setup.
Avoid enabling several overlapping caching systems without understanding how they interact.
4. Reduce Unnecessary Scripts
Third-party widgets, animations, and other scripts can affect loading and responsiveness.
Remove features that do not provide enough value to justify their performance cost. Keep essential tools, such as analytics, when they support your website goals.
5. Improve Hosting Performance
If your page remains slow after basic optimization, check your hosting service.
Slow server responses may require changes to server configuration, resource allocation, or hosting arrangements. Test before upgrading to a more expensive plan.
How Often Should You Test Your Website?
You do not need to test every page every day. Instead, create a simple testing routine.
Test important pages before and after major design changes.
Check your homepage and popular blog posts periodically.
Test again after installing major plugins or changing themes.
Review performance when visitors report slow loading.
Keep a record of scores and key recommendations.
For a small blog, checking important pages monthly and after major changes is a practical starting point. Adjust the schedule if your website changes frequently.
You can also use Google Analytics to understand visitor behavior and identify pages that deserve closer review. Analytics and PageSpeed Insights serve different purposes, so use them together when useful.
Common Mistakes to Avoid
When using Google PageSpeed Insights, avoid these mistakes:
Focusing only on the score: A higher score is useful, but a smooth user experience matters more than chasing a perfect number.
Testing only the homepage: Individual blog posts may contain larger images or different page elements.
Making too many changes at once: Change one important setting at a time so you can identify what helped.
Ignoring mobile performance: Always review the mobile report, especially if your audience frequently uses smartphones.
Installing every recommended tool: More plugins do not automatically mean better performance.
Expecting instant results: Some improvements may require testing, configuration, or help from a developer.
Google PageSpeed Insights makes website performance testing easier for beginners. It helps you identify possible problems, review mobile and desktop performance, and understand important metrics such as LCP, INP, and CLS.
Start by testing your homepage and a few important blog posts. Review the recommendations, optimize large images, check unnecessary plugins, and improve caching where appropriate.
Make changes carefully and test again. Over time, this process can help you create a faster, more reliable website for your readers.
