Wordpress caching with WP Fastest Cache

While blogging in Wordpress, your focus has to be on speed apart from content and SEO. It is because of the criticality of speed and user experience in terms of SEO. Speed has become a critical ranking factor. Your wordpress site needs to be optimized for SEO and must load fast. If it takes more than a few seconds to load, your blog will experience higher bounce rate or lower average engagement rat. It will also lose rankings in searches.

Core web vitals score is a crucial factor affecting SEO and rankings. When it comes to loading a Wordpress site faster, caching and cache plugins have a central role to play. Wordpress websites can be optimized to load in less than a second. If done properly, you will have a Wordpress blog loading in milliseconds.

You will need a fast loading theme (preferrably Generatepress or Astra), a fast server (hosting) and a nice caching plugin to optimize and speed up your wordpress blog. Caching is critical to Wordpress performance since it reduces the time taken to serve a web page when requested. Without caching, Wordpress serves web pages when requested by sending a request to your mysql database. The server receives the information from the database and then serves it to the user. However, when you have caching active, pages can be served directly from the cache (memory), getting rid of an excess roundtrip and reducing the time taken for loading pages.

There are several excellent caching plugins in Wordpress plugin repository, that will help you speed up your website and improve your core web vitals score. Some of them include caching features as well as other speed optimizations like code minification, compression and CDN.
