WordPress site: Performance optimisation
**Challenge** The website's performance on both desktop and mobile had declined significantly. Users were unable to reliably view images, large CSS and JS files were causing delays in rendering, and images were not resizing properly for different devices, leading to a poor user experience and slow responses from the admin panel. The client required a swift and dependable performance fix without compromising site functionality.
**Solution** We conducted a quick audit to pinpoint heavy assets, bottlenecks in JS/CSS, and issues with image handling. We improved caching by replacing and reconfiguring WP Rocket, introduced automated WebP conversion through WebP Express, eliminated unused CSS and JS, implemented critical CSS, and optimized image delivery and resizing rules. Additionally, we refined frontend loading logic and enhanced server response patterns.
**Tech** WordPress, WP Rocket, WebP Express, critical CSS, asset minification, server-side tuning.
**Outcome** After our improvements, desktop performance increased by approximately 20%, and mobile performance improved by around 30%, as confirmed by performance assessments post-work. The site now features consistent image rendering, quicker page load times, and a more seamless admin experience.
