If you need help with enabling this data communication protocol, make sure you check our Web Maintenance services.

What is HTTP/2?

It’s a data communication protocol between clients and servers. It’s an expansion on the features of HTTP/1.1

Why is HTTP/2 Important?

HTTP/1.1 has been relatively unchanged since 1997. The new protocol brings improvements in terms of new features and performance.

It’s supported by a variety of web browsers, servers and most recently by Google Pagespeed Insights.

Features of HTTP/2

The main features of HTTP/2 are:

  • Faster encryption
  • Multi-host multiplexing
  • Header compression to improve both performance and security
  • Improved stream prioritisation

Benefits of HTTP/2

The main benefits of HTTP/2 are:

  • It improves the performance (= page load speed) of your website overall
  • It’s particularly geared towards optimising your website’s mobile performance
  • It optimises the uses of resources on your network
  • It improves the security of data communications
  • Coming May 2021 and the Core Web Vitals, it will help improve your rankings

HTTP/2 and Your Website

Before you can enable this protocol, you want to check whether your server supports it or not.

How to Check HTTP/2 Support

To check if your server supports the HTTP/2 protocol:

  1. Visit
  2. Enter your website URL in the corresponding field

check support for hhtp/2

How to Enable HTTP/2 on Your Website

If your server supports this protocol, in theory there shouldn’t be anything else for you to do.

If your server doesn’t support the automatic connection of the protocol, you can follow the steps described in this article (for advanced users of websites on Apache or Ngix servers).
