Does caching improve WordPress site speed?

Absolutely, caching can make your WordPress site load much faster. It works by saving a copy of your website so it doesn’t have to load everything again, every time a user visits. It does so by saving your site’s data in places that are quicker to reach, like in the visitor’s browser or on a third-party server closer to them. You can use plugins such as W3 Total Cache, WP Rocket, etc, that can add caching to your site. To see if caching alone is enough or if there are deeper issues, try running a free speed diagnostic on Fibr.ai; its AI audit shows you what’s really slowing your site down.
