Improving the performance of a WordPress site is crucial for providing a better user experience. Hiring a WordPress agency can undoubtedly help you achieve this from a more structural point of view, but some plugins can result in quick wins.

3. W3 Total Cache

W3 Total Cache is a famous caching plugin that can really improve the speed of your website. It works by caching your pages and posts as static files, which reduces the number of database queries required to generate each page. This can result in improved overall achievement and faster load times.

By installing and configuring either of these caching plugins, you can really improve the performance of your WordPress site without having to spend a dime.
