Post at a Glance
In today’s post we’ll be going over how website speed plays a crucial role in user satisfaction and search engine rankings. If you’re wondering how to improve PageSpeed Insights score, you’re in the right place. Google’s PageSpeed Insights tool evaluates your site’s performance, providing actionable insights to make it faster.
This guide offers 15 fantastic tips, drawing from proven strategies to help you achieve higher scores, better Google Core Web Vitals, and increased traffic. Whether you’re running a WordPress blog or any other platform, these steps can transform your site’s loading times.
PageSpeed Insights analyzes web pages on both mobile and desktop devices, delivering lab data from Google Lighthouse optimization and field data from real users via the Chrome User Experience Report. It scores your site from 0 to 100 in categories like performance, accessibility, best practices, and SEO. A score above 90 is considered good, but aiming higher ensures optimal user experiences. Field data focuses on real-world metrics over 28 days, while lab data simulates controlled environments. Understanding these elements is key to knowing how to improve PageSpeed Insights score effectively.
15 Tips to Improve PageSpeed Insights Score
Why does this matter? Faster sites reduce bounce rates, improve conversions, and boost SEO. Google uses page speed as a ranking factor, especially with Core Web Vitals like Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. By following these tips, you’ll address common issues and see tangible improvements.
Tip 1: Optimize Images for Faster Loading
Images often account for the bulk of a page’s weight, slowing down load times. Start by compressing images without losing quality. Use formats like WebP or AVIF, which offer better compression than JPEG or PNG. Tools like Imagify or online compressors can automate this.
For WordPress users, plugins such as WP Rocket or Optimus handle image optimization seamlessly, converting files to WebP and resizing them based on device needs.
Always add width and height attributes to images to prevent layout shifts:
<img src="example.webp" width="800" height="600" alt="Optimized image example">This reserves space in the browser, reducing Cumulative Layout Shift. Lazy loading is another must: add the loading=”lazy” attribute to non-critical images. This defers off-screen image loading until needed, directly impacting how to improve PageSpeed Insights score.
Implement responsive images with srcset for different screen sizes:
x<img srcset="image-480w.jpg 480w, image-800w.jpg 800w" sizes="(max-width: 600px) 480px, 800px" src="image-800w.jpg" alt="Responsive image">By optimizing images, you can shave seconds off load times, leading to scores in the 90s or higher.
Tip 2: Leverage Browser Caching to Improve PageSpeed Insights Score
Browser caching stores static files like CSS, JavaScript, and images on the user’s device, so they don’t reload on repeat visits. Set appropriate Cache-Control headers in your .htaccess file for Apache servers:
<FilesMatch "\.(css|js|jpg|jpeg|png|gif|webp)$">
Header set Cache-Control "max-age=31536000, public"
</FilesMatch>For Nginx, add similar directives. This reduces server requests and speeds up subsequent loads. WordPress plugins like W3 Total Cache or WP Super Cache make this easy without manual coding.
Combine this with a Content Delivery Network to cache assets globally. Expect a noticeable bump in your performance score.
Tip 3: Minify CSS, JavaScript, and HTML to Improve PageSpeed Insights Score
Unnecessary spaces, comments, and line breaks in code inflate file sizes. Minification removes them, making files smaller and faster to load. Use tools like Autoptimize for WordPress, which minifies and combines files automatically.
For manual minification, online tools like CSSNano or UglifyJS work well. Defer non-essential JavaScript with async or defer attributes:
<script src="script.js" defer></script>This prevents render-blocking, a common issue flagged in PageSpeed Insights. Minifying can reduce file sizes by 20-50 percent, directly contributing to better scores.
Tip 4: Enable Compression to Improve PageSpeed Insights Score
Gzip or Brotli compression reduces file sizes before sending them over the network. Enable it on your server. For Apache:
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>Brotli offers even better compression for modern browsers. Plugins like WP Rocket integrate this effortlessly, compressing assets on the fly.
Compression can cut transfer times in half, boosting your score significantly.
Tip 5: Use a Content Delivery Network to Improve PageSpeed Insights Score
A CDN distributes your content across global servers, reducing latency by serving files from the closest location to the user. Services like Cloudflare or KeyCDN integrate easily with WordPress.
Set up by pointing your DNS to the CDN and enabling asset optimization. This minimizes Time to First Byte and improves global performance, essential for international audiences.
How to Improve PageSpeed Insights Score with Core Web Vitals Optimization
Core Web Vitals are central to boost PageSpeed Insight score. Focusing on them is a direct path to higher scores. Largest Contentful Paint measures loading speed, aiming for under 2.5 seconds. Interaction to Next Paint gauges responsiveness, targeting below 200ms. Cumulative Layout Shift assesses visual stability, with a goal of less than 0.1.
To optimize Largest Contentful Paint, preload critical resources:
<link rel="preload" as="image" href="hero-image.webp">Reduce resource load duration by compressing images and using CDNs. Eliminate render delays by in-lining critical CSS.
For Interaction to Next Paint, break up long JavaScript tasks. Use requestIdleCallback for non-urgent work:
window.requestIdleCallback(() => {
// Perform non-critical tasks
});Yield to the main thread with setTimeout in event handlers to avoid blocking.
Cumulative Layout Shift fixes include setting dimensions on images and embeds, avoiding dynamic content insertions without reserved space. Use font-display: swap for web fonts to prevent invisible text shifts.
These optimizations ensure your site passes Core Web Vitals assessments, elevating your overall score.
Tip 6: Reduce Server Response Time
Slow servers drag down scores. Optimize Time to First Byte by choosing fast hosting, like managed WordPress hosts with built-in caching. Minimize redirects and avoid cache-busting query strings in URLs.
Database optimization helps too: clean up transients and use plugins like WP-Optimize to trim excess data.
Tip 7: Eliminate Render-Blocking Resources
JavaScript and CSS in the head can block rendering. Move non-critical scripts to the footer or defer them. Inline small CSS snippets for above-the-fold content.
Tools like Critical CSS generators extract and inline essential styles, deferring the rest.
Tip 8: Prioritize Visible Content
Load above-the-fold content first. Use fetchpriority=”high” on key resources:
<img fetchpriority="high" src="above-fold-image.jpg">This tells the browser to load them sooner, improving perceived speed.How to Improve PageSpeed Insights Score Using WordPress PluginsWordPress sites benefit from specialized plugins. WP Rocket caches pages, minifies files, and optimizes databases in one package.
PageSpeed Ninja handles lazy loading, WebP conversion, and critical CSS generation.
WPSpeed offers just-in-time preloading and integrates PageSpeed Insights directly for real-time tweaks.
Install one, configure settings, and test scores before and after.
For images, Smush or EWWW Image Optimizer compress and serve next-gen formats. Combine with a caching plugin for best results.
Tip 9: Optimize Web Fonts
Web fonts can cause flashes of invisible text. Preload them:
<link rel="preload" as="font" href="font.woff2" crossorigin>Use font subsets to load only needed characters. Limit font families to two or three per page.
Tip 10: Implement Lazy Loading for Media
Native lazy loading is simple, but plugins enhance it for iframes and videos. This saves bandwidth and speeds up initial loads.
Tip 11: Remove Unused CSS and JavaScript to Improve PageSpeed Insights Score
Bloat from themes and plugins slows sites. Use Asset CleanUp to disable unused assets on specific pages.
PurgeCSS analyzes and removes redundant code, slimming down stylesheets.

Enable HTTP/3 for faster connections. Monitor with tools like WebPageTest for waterfalls showing bottlenecks.Use performance budgets to cap resource sizes during development.
Tip 12: Monitor and Test Regularly
Run PageSpeed Insights frequently. Compare lab and field data to spot discrepancies. Tools like Chrome DevTools help debug issues locally.Set up Google Analytics to track real-user metrics and correlate speed with engagement.
Tip 13: Optimize for Mobile First
Mobile scores often lag due to slower networks. Use responsive design, compress assets more aggressively, and test on emulated devices.
Tip 14: Integrate AMP if Suitable
Accelerated Mobile Pages load instantly. For blogs, the AMP plugin converts posts, potentially perfecting mobile scores.
Tip 15: Stay Updated with Best Practices
