Although all it takes to load a website is a click of the button for you, there’s much more for computers to handle. That one click and one second that will take until a page is displayed in front of you may hide dozens if not hundreds of HTTP requests to the server. Obviously, the more information goes back and forth, the longer you will have to wait for a site to load.
One of the easiest things you can do to speed up your site is to have a good hosting company. But when you decide to go even deeper to speed up your WordPress website, you should take care of HTTP requests.
For starters, you should test your website to see how many requests does it take to load a particular page. There are different ways of testing that. Instead of showing you all the possibilities, it will suffice to enter an URL in the HTTP Requests Checker. You will get the results immediately, and hopefully, you won’t have more than 30-ish requests. If you do, it’s time to reduce the number of HTTP requests and speed up your WordPress site.
