Building a WordPress website is quite easy, which is why 30 % of the websites on the internet being powered by WordPress. Having a slow WordPress website is a recipe for disaster. Not only does it make the user experience horrible, but it also has serious damage to the SERPs of the website.
Recent studies by SEO experts have proven that site-loading speed of more than 2 seconds typically results in about 42 percent of visitors bouncing off the website. Knowing that having a fast website is essential for the growth and longevity of the website.
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.
2. Theme
One of the biggest factors that affect a WordPress website loading speed is the theme of the website. WordPress themes are usually built with lots of features like sliders, carousels, dynamic content displays, widgets to name a few.
Having lots of these features on a page can cause an increase in the loading time of the website. The best option when choosing a theme for a website is a lightweight theme. Here are a few lightweight themes to choose from:

3. PHP
PHP a.k.a Hypertext Preprocessor is an extensively used open-source scripting language that is suited for web development and can be embedded into HTML.
The majority of WordPress scripts are written in Hypertext Preprocessor, along with your plugins and themes. Make sure your web hosting service provides you with PHP version 7 upwards else look for another hosting service. The higher the PHP version, the more requests that can be handled per second.
4. Caching
To understand what caching is as a process we must first understand how a web server works. When a visitor accesses a URL on your website, it sends a request to the webserver which processes the request and displays a webpage for the visitor.
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.
