HTTP/2 is a new data transport protocol that will drastically speed up searches and can help your SEO a lot. The “old” HTTP1.1 protocol allows servers to send files in a sequence one at a time, and that line must be opened and closed after each file is sent. For this reason, this process may take some time. HTTP/2 is far more efficient than the older HTTP/1.1 protocol and is capable of transferring data at much higher speeds. HTTP/2 offers a drastic increase in speed, as it can send a large amount of data at once.

In this text, we will explain what news HTTP/2 brings and what they mean for optimization and for websites in general.

The HTTP/2 revolution in search

“HTTP/2 will make our applications faster, simpler and more robust – a rare combination – allowing us to overcome many of the HTTP/1.1 workarounds previously implemented in our applications and to solve these problems in the transport layer itself. Even better, it also opens up a whole new range of opportunities to optimize our applications and improve performance !” they say from Google .

In a nutshell, this means that servers can now open a connection to a browser and send all the necessary files and data of a particular website over that single connection. After that the link is closed and the site can be displayed.

HTTP/2 has a lot of great features that can help you speed up your site’s load time. The most important, of course, is full multiplexing , which means that multiple requests can occur simultaneously over a connection that is open during the transmission process.

Another new thing is Server push. Server push allows you to send site data to the user before he even asks for it. When the server notices that HTML requires several assets, it can send them all at once without asking. When used carefully, we can pre-send to the user what we know will be needed from the data for the page they request.

Crazy and fast

Speed ​​is essential. Site speed has been one of the key ranking factors for years. With the introduction of mobile-first indexing, Google has made loading speed even more important.

Sites are getting bigger and more demanding when it comes to the amount of data on them. Lots of assets like HTML , JavaScript , CSS , images mean longer loading times. HTTP/2 makes this process much more manageable for servers and browsers, which speeds things up drastically. Note that the emergence of HTTP/2 does not imply the automatic retirement of HTTP1.1, as browsers will still use the old protocol as a fallback.

Google has announced that it has started sending notifications to let website owners know that it has started crawling their websites with the advanced HTTP/2 protocol. Notification is sent only to those whose sites have been upgraded. Google will determine whether a site benefits from the new protocol. If it finds no benefit, Google may decide not to use the new HTTP/2 protocol.

Deploying HTTP/2 is fairly simple and your server may already be using it. You can test this using the HTTP2.Pro tool.
