Browser caching allows you to speed up your website by storing files locally in the user browser. Essentially, browser caching looks at files you’ve defined as files that don’t change very often and downloads them to the visitor’s browser just once. So the next time a visitor visits your home page, they'll already have certain files such as a logo, your style sheet, and credit card icons in the footer of your site.
This doesn't help the very first page someone visits, but it will help with each future page they visit on the site. We're going to configure a caching plugin and discuss page caching and when you'd want to use it.
