Optimization of website speed on WordPress
Website Performance Optimization on WordPress
The project involved comprehensive optimization of a website built on WordPress using the Gutenberg block editor. All work was done manually — without the use of third-party optimization plugins, ensuring a clean, controlled code structure and minimal server load.
The following was carried out:
– compression and conversion of all images to WebP format with correct output via srcset;
– localization of Google fonts to eliminate external requests and improve the First Contentful Paint metric;
– optimization of styles and scripts — minification, merging, and lazy loading of non-critical resources (defer, preload, critical CSS);
– manual cleaning of HTML output from unnecessary code, comments, and unused dependencies.
The result was perfect website performance:
– Google PageSpeed scores reached 95–100 points on desktop and 85–95 on mobile devices;
– the site loads in less than a second on modern devices;
– the number of server requests and the amount of data transferred were reduced.
This project demonstrates an approach to "clean optimization" — where performance is achieved not through plugins, but through a deep understanding of the WordPress structure, browser mechanisms, and modern frontend development standards.
