Factors affecting WordPress website loading time

1. Web Hosting Service

Web Hosting service is a company that stores all of your website’s data. You settle a plan and upload images, videos, contents, and more that would be stored on the host server. The hosting company gives you access to the data, manage it, and show it to your visitors.

When deciding on a WordPress host you may not even think of researching into what network they’re using, however, you should. This will have a large impact on your website’s overall performance. Many hosts will leave this out of their advertising as they’ll choose the cheapest network to reduce costs.

Caching is the easiest way to reduce the loading speed of a WordPress website. Caching sends requests to the webserver and saves these requests on the RAM/disk, basically making it easier and faster to display as a webpage when next a visitor sends a request.

5. Overload Plugins

Plugins are quite nice, get the job done easily without the stress of coding, hence everyone can build a website. Yet you are advised that having much of it on your WordPress website often slows down the website.
