1) Server Requirements

As we all know the importance of choosing a good hosting provider for website performance. We recommend you not to use low-quality shared hosting. Kindly try to get service from a well-known hosting provider with good support.

Here is a list of things for you to check a good server.

  • Response Time: Your server response time is very important because a lot of things depend on server response time. The first thing that Google Page Speed (aka Lighthouse) checks is your server response time. No matter how hard you try to improve your score it will be not beneficial if the server response time is not fast enough. Usually, google looks for less than 500ms(milliseconds) response time for dynamic sites.
  • Server Location: Try to choose a server that is closer to your target audience. Like if you are a Canada-based eCommerce retailer then try to avoid taking servers from Europe. It will only increase the response time.
  • HTTP2 Support: Most of the browser supports HTTP2 protocol. You have to check with your hosting provider if they support HTTP2.
  • SSL Certificate: You will need an SSL Certificate to enable HTTP2 protocol from your server. So have an SSL certificate for your domain. You can get free a free certificate from Let’s Encrypt.
