Let’s get started!
What are preload key requests?
As the name suggests, preload or preloading is a system that gives hints to the web browser to load necessary resources as soon as possible. And preload key request means adding preload requests for these essential resources/files. So basically, preload informs the browser to cache these resources on the web page immediately as the page starts loading. Caching these resources on a webpage ultimately reduces the page loading time and increases page speed.
So with preloading, when a user visits your site, their browser downloads the necessary file early and makes the rendering process faster. You can preload various resources on your site. The most common resources that people preload on their sites are:
- Script files
- CSS files
But you can also preload links, videos, documents, workers, objects, and anything else you feel is important.
Why is it critical to preload key requests?
Preloading resources on the webpage is an amazing tool to optimize web performance. It boosts your page speed and provides an excellent user experience. To better understand how preloading fastens page loading, let’s take a look at what happens when a visitor visits a web page.
When a visitor arrives at your web page, their browser sends a request to download and parse the HTML and other linked source files that are needed for the page to load. During this time, when the files are being downloaded and processed, page loading stops. When you have a bulk of files on your web page, it increases the loading time and frustrates the user. But with preloading, you can tell the browser to download specific resources earlier without blocking the rendering process. Thus, when a user visits your site, their browser downloads the necessary resources early, thus reducing the time to load the page.
It also instructs the browser to identify the resource type to tell if the same resource can be used in the future. It caches these types of resources on the web page immediately. Caching these resources greatly reduces the loading time and boosts your page speed. Further, increasing the page speed also improves the site’s SEO and ultimately ranks your site higher on google.
Here you can see how beneficial it is to preload resources on the web page. Now let’s take a look at how you preload key requests on your WordPress site.
