How to optimise your website for mobile page speed

Ensuring your website loads quickly on mobile devices is crucial. Not only does a speedy mobile site improve user experience, but it also positively impacts your search engine rankings. Here’s a guide to help you optimize your website for mobile page speed.

So we are running some tests on our own website, the goal it to “go green in Google Pagespeed Insights (80% +)

1. Minimize HTTP Requests

Every element on a webpage—images, scripts, and stylesheets—requires an HTTP request. The more requests, the slower the page load time. Reduce the number of elements on your page, combine files, and use CSS sprites for images to minimize these requests.

2. Optimize Images

Images are often the largest files on a webpage and can significantly slow down loading times. Use responsive images that adjust to different screen sizes and formats like WebP, which provides superior compression. Tools like TinyPNG or ImageOptim can help reduce image sizes without compromising quality.

3. Enable Browser Caching

Browser caching stores some data on the user’s device, so they don’t have to re-download it every time they visit your site. Set an expiry date on your cache to specify how long browsers should keep this data. This step can dramatically decrease load times for returning visitors.

4. Use Content Delivery Networks (CDNs)

CDNs distribute your content across various servers worldwide, reducing the distance between your site and the user. This setup decreases latency and speeds up load times, especially for global audiences. Popular CDN services include Cloudflare, Amazon CloudFront, and Akamai.

5. Minify CSS, JavaScript, and HTML

Minification removes unnecessary characters from code—like white spaces, comments, and line breaks—without altering its functionality. Tools like UglifyJS, CSSNano, and HTMLMinifier can help streamline your code, making it faster to download and execute.

6. Prioritize Above-the-Fold Content

Ensure the content that appears on the screen before scrolling (above-the-fold content) loads first. This gives the impression of a faster load time and improves user engagement. Use lazy loading for images and defer offscreen content until it’s needed.

7. Leverage Browser Caching

Implement caching policies to store certain static resources locally in the user’s browser. This reduces the need to fetch them again on subsequent visits, thus speeding up load times for repeat visitors.

8. Reduce Server Response Time

Your server’s response time should be under 200ms. Optimize your database, use a fast web hosting service, and employ a performance-optimized server. Tools like Google PageSpeed Insights can help identify and address server issues.

9. Enable Compression

Compressing files can reduce their size, leading to faster download times. Gzip is a popular compression method that can be enabled through your server settings. Ensure that your server supports it and is configured correctly.

10. Eliminate Render-Blocking Resources

JavaScript and CSS files can block the rendering of your webpage, causing delays. Identify these render-blocking resources using tools like PageSpeed Insights and remove or defer them to ensure they don’t interfere with the critical rendering path.

11. Implement Accelerated Mobile Pages (AMP)

AMP is an open-source initiative aimed at optimizing mobile pages for speed. AMP pages are lightweight and load almost instantly, providing a smooth user experience. Consider implementing AMP for your content to enhance mobile page speed.


Optimizing your website for mobile page speed is not just about improving user experience—it’s also about staying competitive in search rankings. By implementing these strategies, you can ensure that your site loads quickly on mobile devices, keeping your visitors engaged and satisfied. Stay ahead of the curve by regularly testing and updating your site’s performance, and you’ll see the benefits in both user retention and search engine visibility.
