In this article, you will learn why it is important to add caching plugins in your WordPress website.
I will also cover some of the best WordPress caching plugins that are essential in speeding up a website.
What Is Caching?
In computer terminology, cache is a temporary storage area. It is a type of temporary memory that is used to increase the speed of data access.
Normally, when you work on a computer, the data required for any process resides in the main memory i.e. hard disk. But when you use that same data frequently then it is transferred to the cache memory temporarily for speeding up the data access.
The process of storing and accessing data from a cache is known as caching.
WordPress websites works on the same concept. With the help of caching plugins it speed up your websites to load faster.
Normally, each time a user visits your WordPress website from a browser, the browser requests a web page and the server in which your website is hosted, has to fetch the required information from its databases and also performs several other complex and time consuming calculations before the web page is loaded in the users browser.
If there is no caching then each time a user request the same page the server will have to repeat all the process as mentioned above increasing the load time.
Here comes the role of caching to make the process simpler and faster.
How Caching Works?
When you enable caching plugin in your WordPress website the processing of fetching information from the databases and performing other steps are skipped.
Instead, caching plugin makes a copy of your website and serve your users that copy which makes your website load faster thereby, reducing load on your host server.
Why Should You Use A Caching Plugin in Your Website?
Google likes faster websites. Yes it is true. If your website load faster than your competitor then your website will be given preference by ranking it higher on Google Search results.
Although there are many other factors which results in higher ranking in Google, speed of a website is one of the most important factor.
Thus, keeping in mind the SEO benefits a fast websites brings, you should start using a caching plugin in your site.
A caching plugin reduces load on your host server and makes your websites extremely fast, which leads to better SEO scores and increased user satisfaction.
Other benefit of using a caching plugin is increased conversion.
A faster website reduces bounce rate by encouraging your users to engage more with your websites thereby spending more time on your website by visiting multiple pages.
When your users are spending more time in your site it increases your chance of getting more sales and conversions. It can also help you grow your email list if you're using email subscription forms on your site to collect leads.
Now let's look at the best WordPress caching plugins that you can use on your website to make it extremely fast to load.
