What is Gzip compression and how does it help in speeding up a WordPress site?
When a user visits a WordPress site, their browser sends a request to the server to fetch the files required to display the webpage. Gzip compression compresses these files before they are sent, allowing them to be transferred over the network more quickly. Once the compressed files reach the user's browser, they are automatically decompressed and displayed as usual.
Gzip compression helps in speeding up a WordPress site by reducing the amount of data that needs to be transferred between the server and the browser. Smaller file sizes mean faster loading times, which improves the overall performance and user experience of the website. Additionally, it also helps save bandwidth for both the server and the user, as less data needs to be transmitted.
Enabling Gzip compression on a WordPress site can be done by adding some code to the website's .htaccess file or by using caching plugins, which often include an option to enable Gzip compression.
