Another important factor influencing the WordPress site speed is proper hosting. When a user enters your website and clicks on part of your site’s menu, it means they have a request from your site. 

The site sends this request to the server, and the server forwards it to the database by making changes. Next, the database checks the answer and provides the result to the server so the server can provide it to the user.

These transitions require high processing and response speed, especially if there are a lot of requests from your site in a short time. What happens if the hosting site is not vital?

Prolonged loading, 5xx series error are some of the most critical problems that your site may face and will make the user leave your site faster than you think. Therefore, please be careful in choosing and buying a good host. Apart from creating a good user experience, this issue will also tremendously impact your site’s SEO.

You need to use a content distribution system or CDN to solve this issue. CDNs are servers located in different countries and store and move all the elements and content on your site.
