Website optimization is extremely important. There are numerous little things you need to think of, such as your page loading speed, caching, image compression, lazy loading, hosting site analytics locally, etc. Luckily there are a bunch of different plugins that can help you fix that.

There are cache plugins, image optimization plugins, plugins for better loading times, or Google Analytics plugins that fix mistakes associated with Google. In short, there are many. However, before choosing a plugin, make sure it is of good quality. What we mean by that is look at the number of active installs, when it was last updated and how frequently it is updated, check the reviews, and if you’ll get any technical support. Remember, what matters is the quality of plugins, not the quantity.
