The three great options for hosting are:

  • VPS: it’s a virtual private server. It’s faster than a shared host but uses many machines rather than one.
  • Dedicated: it’s an expensive server. In this, you can rent an entire machine for your configuration.

6. Implement Gzip Compression

Enabling Gzip compression on your HTTP servers is an effective website optimization technique. According to web developers, it decreases the loading of web pages effectively. In this method, Gzip compression reduces the size of HTTP responses for certain file types. Usually, it is used for textual responses only. Besides reducing load time, it saves on bandwidth.

9. Reduce the Number of Plugins

Plugins have reusable functionality. Usually, they are used in CMS like WordPress or pre-built website platforms. Plugins offer functionality like analysis or allow leaving a comment on blog posts. 

But plugins can impact website speed. Each plugin loads additional CSS and JavaScript files. Even some plugins increase TTFB as they need additional processing on the server. 

That’s the reason reducing plugins can be a great website optimization technique. You should delete plugins that are not important to the server. And keep updated to improve website performance.
