How to Add Expires Headers in WordPress

What Are Expires Headers?
Expires headers let you tell a visitor’s web browser whether it should load a given resource from the local browser cache or whether it needs to download a new version from the web server.

Let’s set a duration for the cached version of different file types before that file “expires” and the browser must download it from the server again.

Let’s say you want to control browser caching behavior for PNG image files on your site. If you set the Expires headers for PNG files equal to one month, a visitor’s browser will Load the already-downloaded version from the cache for one month after the initial access download.
Re-download that file from the server after one month.
You can set different Expires headers for different file types, which gives you granular control over your site’s browser cache.

How to Add Expires Headers With a WordPress Plugin
If you don’t feel comfortable adding the expired headers code yourself, you can also find some WordPress plugins that can do the job for you. Some of these plugins add expire headers, while others use cache-control. Either way, the end result is that your WordPress site can benefit from browser caching.

One solution is to use a caching plugin if your host hasn’t already implemented caching for you. A great option here is WP Rocket. As soon as you activate the WP Rocket plugin, it automatically enables browser caching for you – there’s no need to configure any other settings.
