5 Top WordPress Caching Plugins Comparison

What is Caching?

A cache is a place to temporarily store data. The main purpose of cache is to make use of the temporary file instead of retriving the data from server each time.

Active data is often cached to reduce load times. When you are a frequent visitor of a particular website, the website keeps a cache in your browser.

This means that the browser needs to receive less ‘fresh’ and only expired information from the site, resulting in a faster load time.

In WordPress, we have caching plugins which dynamically generated HTML files and serving them from the cache.

Instead loading all the PHP scripts from WordPress every time you hit refresh.

The result is that your site loads far quicker for all its visitors.

How to Select the Best WordPress Caching Plugin for You

Choosing a caching plugin depends on what you expect the plugin to do and identify the criteria.

Criteria could include:

1. Cost. Plugins for wordpress are available for free and paid. It depends on how rich th plugin is in features.

It can range from $0 – $100+. So cost can also effect your criteria

2. Complexity and intuitiveness. This will depend on your own experience with plugins and wordpress.

Can you handle the complex settings of the plugin and happy to dive in to get it sorted without much help.

or do you need a simple, step-by-step procedure to get you up and running?

3. Power and functionality. Some plugins come with extra features such as integration with CDN (content delivery networks), GZIP compression tool, and minification (removing all unnecessary characters from source code and minifying it to a smaller size).

These above functions enable your site to run even faster.

4. Support. Some plugins have support lines, forums, documentation – the full shebang. Others may have little support or even none at all. How much support do you feel comfortable having?

So now that we have our basic criteria sorted out,

Let’s have a look at the top 5 most popular caching plugins:
