What’s the difference between HTTP/2 and HTTP/1.1?

HTTP/2 is the newer protocol for transporting data. HTTP/2’s predecessor is HTTP/1.1. The main difference between HTTP/2 and HTTP/1.1 is that with HTTP/1.1 data can only be processed on one line at a time. The line must open and close after each file has been sent. This makes the process incredibly slow.

With HTTP/2, speed is dramatically boosted, and more data can be sent at once. So, the most important things to know about HTTP/2 is that it speeds things up and because of that it can boost SEO.

How do I know if I am using HTTP/2?

Setting up HTTP/2 is pretty easy. You may actually already be using it without knowing. If you want to find out if you’re already using HTTP/2, you can search your URL using the HTTP.Pro site. If you are using HTTP/2 already, then you’re set! You don’t need to do anything else.

How to start using HTTP/2

If you find out you are still using HTTP/1.1 and want to switch over, you’ll need to get an SSL certificate. Once you’ve done that, the easiest way to migrate over to HTTP/2 is by registering with a content delivery network (CDN) and then following the necessary steps.

If this sounds too confusing, don’t worry. You can also ask a web developer to help you set up HTTP/2.
