Achieving a 90–99% speed score in Google PageSpeed Insights is possible with the right strategy, tools, and attention to performance best practices. Here’s a detailed step-by-step guide to help you optimise your website for top scores:
🔧 1. Optimise Images
Compress and resize images without losing quality using tools like TinyPNG or ImageOptim.
Use modern formats like WebP instead of JPEG or PNG.
Implement lazy loading so images load only when they come into view.
🧠 2. Minimize and Combine Files
Minify CSS, JavaScript, and HTML to reduce file sizes.
Combine multiple CSS or JS files to reduce HTTP requests.
Remove unused CSS/JS using tools like PurifyCSS or manually auditing with DevTools.
🚀 3. Use a Content Delivery Network (CDN)
CDNs like Cloudflare or BunnyCDN deliver content from servers closer to the user, reducing load times globally.
📦 4. Enable Caching
Use browser caching to store static files on the user’s device.
Leverage server-side caching plugins (e.g., WP Rocket, LiteSpeed Cache) to serve faster pages.
💡 5. Limit Unnecessary Plugins & Scripts
Deactivate and remove plugins or scripts you don’t use.
Avoid bloated themes and heavy third-party embeds.
Only load scripts where they are needed (e.g., no jQuery on pages that don’t use it).
📲 6. Implement Mobile Optimization
Use responsive design and test your layout on various devices.
Ensure text is readable and buttons are easily clickable on small screens.
⚙️ 7. Choose a Fast Hosting Provider
Invest in high-performance hosting with SSD servers and low latency.
Consider managed WordPress hosting or VPS if shared hosting is slowing you down.
🔒 8. Enable GZIP or Brotli Compression
Compress server responses using GZIP or Brotli to shrink the amount of transferred data.
🔄 9. Use Efficient Fonts
Host fonts locally or use font-display: swap for better performance.
Limit the number of font weights and families.
📈 10. Regularly Audit with Google PageSpeed
Test regularly and address any new issues that arise.
Use Lighthouse reports and tools like GTmetrix to get a deeper look.
By following these steps consistently and addressing any performance bottlenecks, you’ll be well on your way to achieving a 90+ score on Google PageSpeed Insights—and providing your users with a lightning-fast experience.
