Guide to Caching in WordPress

The website loading speed has significantly gained prominence with the evolution of the trends in the digital sphere. It is a huge determinant of the user experience that a website will eventually offer to their audience.

Additionally, the page loading time is also becoming a priority due to its considerations around search engine rankings. Your website’s aesthetic design and each of its amazing functionalities will fail to impress the audience if your website fails to load in the right time.

47% of consumers expect a web page to load in 2 seconds or less. As per a report, if your website fails to load within these seconds as and when a request is made, it will face high abandonment rates. With so much at stake, it has become a compulsion for websites to take care of their page loading times.

Talking of the obvious, it is true that your web host service provider plays the most important role when it comes to determining the loading speed of your website. However, there are a few handful factors as well that can positively impact the loading speed of your website.

We are talking about implementing ‘Catching’ and ‘Content Delivery Network’. While implementing a CDN service comes at a more advanced level for brands, Caching can be easily implemented by websites of all levels.

In this blog post, we will help you explore your options for implementing Caching on your website so that you can effectively improve its loading speed.

What is Caching?

When Caching is in place, your website page is served quite quickly when compared to a non-cached installation. Simply explained, when a new visitor arrives on your website, their request for accessing your web page is received and processed on the server. Once processed, the web page is turned into an HTML file and sent to the web browser for display.

This includes all the HTML, CSS, JavaScript, images, latest posts, the header and footer, the sidebar widgets, and everything on the site. However, when they visit your page again, (if Caching is in place) this HTML which has already been stored, is instantly sent to the browser. Hence, the web page loads swiftly.

When you have a website which has caching implemented on it, all this heavy-lifting is duly taken care of. Since the initial time-consuming process is done once, the request is delivered much faster. This, eventually, loads your website in an instant for the browsers of your site visitors, enhancing their user experience.
