Browser caching (or page caching) is a system of storing a local copy of resources or webpages, which are expected not to change (or at least not very often). Images, CSS files, and JavaScript files don’t need to be loaded on every page request and storing a local copy of these files greatly improves page load time.

In a world where information is available at our fingertips, the expectation is that the retrieval of that information should be fast. When a site is slow to load the user often will lose patience and search for a new option in his favorite search engine. (Not only that, but Google prefers to display results that load in under 1.4 seconds. In other words, a slow site can negatively impact your Google rankings.) 

Browser Caching Benefits:

  • Larger revenue – Faster page loads make for a higher chance that someone visiting the site will stay on the site longer. Conversion rates are proven to increase
  • Maintainability – Site maintainers also benefit from site speed. Larger sites, especially sites that are built with a CMS, require site maintainers to frequently update and information on the site. Improved page caching provides a friendlier environment for any maintainer.
  • Savings on Bandwidth – Sites without the proper page caching configured will end up requiring more bandwidth. Higher amount of calculations happening on the backend to pull the page down to the user require more bandwidth. Since bandwidth = money, lowering your required bandwidth will help lower your hosting costs.
