PageSpeed Insights in WordPress
When it comes to web performance and SEO, one tool keeps popping up: Google PageSpeed Insights. If you’ve ever tested your site and felt confused by the results, you’re not alone. The metrics can look technical or overwhelming at first—but once you understand them, they become a powerful guide to improve your WordPress website.
In this article, we’ll break down what PageSpeed Insights really measures, how to interpret the results, and what practical steps you can take to boost your score without diving into complex technical jargon.
What Is Google PageSpeed Insights?
PageSpeed Insights is a free tool from Google that evaluates a web page’s performance for both mobile and desktop devices. It provides a score from 0 to 100 and offers suggestions to improve the user experience.
The key: this score isn’t a final verdict, but a useful reference to understand how your site performs. And the best part? Many of the suggestions it provides can be easily applied to WordPress.

What Does PageSpeed Insights Measure?
PageSpeed splits its results into two main areas:
1. Field Data (Real-World Performance)
Based on actual user data collected through the Chrome UX Report. If your page gets enough traffic, you’ll see metrics like:
- First Contentful Paint (FCP): when the first visible content appears.
- Largest Contentful Paint (LCP): when the largest visual element loads (e.g., an image or headline).
- Interaction to Next Paint (INP): measures responsiveness after a user interacts.
- Cumulative Layout Shift (CLS): tracks unexpected layout shifts.
2. Lab Data (Simulated Performance)
This is a controlled test that simulates how your site performs in typical conditions. It includes additional metrics such as:
- Speed Index
- Time to Interactive (TTI)
- Total Blocking Time (TBT)
Plus, it provides specific tips for improvement.
What Is a Good PageSpeed Score?
- 90 to 100: Excellent
- 50 to 89: Needs improvement
- 0 to 49: Poor performance
But remember: the goal isn’t to reach 100 just for the sake of it. What truly matters is creating a fast, stable, and enjoyable experience. At Floix Agency, we focus our technical audits on balancing performance with real usability.
How to Improve Your PageSpeed Score in WordPress
Here are some effective best practices you can apply:
1. Optimize Your Images
Avoid heavy files. Use modern formats like WebP and compress your images before uploading. Plugins like ShortPixel or Imagify help automate this process.
2. Enable Lazy Loading
Load only images that are visible on the screen. WordPress includes lazy loading by default since version 5.5.
3. Minify CSS and JavaScript
Tools like Autoptimize or WP Rocket reduce file sizes, making your site load faster.
4. Remove Unused Resources
Clean out unused plugins, fonts, scripts, or styles. Less clutter means better performance.
5. Use Quality Hosting
A slow server can undermine all your optimization efforts. Choose a host optimized for WordPress performance.
6. Implement Caching
Plugins like WP Super Cache or W3 Total Cache help deliver faster page loads by serving stored versions of your pages.
7. Avoid Heavy Plugins
Not all plugins are optimized for performance. Stick to well-coded ones and review their impact regularly.
Bonus Tools That Complement PageSpeed Insights
Alongside PageSpeed, consider using:
- Lighthouse: the core engine behind PageSpeed, available in Chrome DevTools.
- GTmetrix: great for visual analysis and tracking performance over time.
- WebPageTest: allows testing under different network conditions and locations.
PageSpeed Insights isn’t just a tech score—it’s a valuable resource to understand your website and improve it step by step. Its metrics are aligned with what Google values most in user experience.
Use it as a strategic ally. Each technical fix adds up to better speed, higher satisfaction, and stronger rankings.
