How WordPress Cache Plugin works?

First we need to understand that how a WordPress website works. Once a user visit a WordPress website how it works. Let me explain you in simple way and step by step as well.

  1. First a user open your website your url on browser.
  2. This browser sends a request to your website server to fetch you website content. It means you send a request to your website server so that you can see website content.
  3. Your website server receives your request and processes it. Services looks for the content on your website database and send your data on your browser in simple web page format.

It process works every time, when you open a page of your website or post of your website or open any image etc.

Now, you understand that every WordPress website works on client/server architecture. Once your website visitor’s increases the number of request to server also increases and it impact the speed of your website as well.

To reduce the number of request and reduce the server load WordPress Cache plugins are very effective. WordPress cache plugins instructs the server to copy of copy of most commonly used pages/posts  files into the disk or RAM (These are called cache files). In this way, if the same page/post or file request comes from the same user or another user Server can use those files from the Disk/RAM (Cache).  (No need to process the same request again and again).  This reduce the server load and same request page/files load faster from the cache files. In simple words, WordPress cache plugins reduce the work required to generate a page view.

Apart from this important task, cache plugins also optimize your website code, use compression technique to optimize your website images and other coding.

  3. Boost in search engine results: If your website loads faster, it makes a positive impact on search engines and they give it priority of your competitor’s website. It helps to improve your website ranking.

  5. Compression: Most of the WordPres Caching plugin use compression technique to reduce the size of your website files (css/html/javascript/jquery) so that they can load faster on your website and allow your website to load faster.
