Everyone loves a fast loading website. Website owners, site visitors, and even Google all have a special place in their hearts for websites that load quickly and efficiently. And, with good reason: excessive load times can drive away site visitors, prevent conversions, and cause a site to rank lower in search engine results pages.
But what is “caching,” why it is so important, and what should you look for in a good caching plugin. In addition, what are some of the top caching plugins on the market today?
What is Caching?
In short, a cache is a place in a computer’s memory where it temporarily stores data for later use.
Caching recognizes this problem, and creates a clever work-around to speed up site performance. When a browser requests static content from your website, such as your published posts, rather than retrieving a fresh version every time, the server uses a snapshot of the previous output, stored in the cache, and delivers that to the visitor.
This works because static content remains unchanged unless you, as the site owner, go in and make direct changes to it. By caching the content on your website that rarely changes, you are able to serve up an already readable version directly to your site visitors without having to find and retrieve each element, synthesize it into a complete page, etc. This reduces your site’s page loading times significantly.
Why is Caching Important?
Caching your WordPress website is beneficial for several reasons:
- It is an effective way of speeding up your website
- It provides a better user experience for site visitors
- Google and other search engines notice faster websites and rank them higher
- You reduce the strain on server resources (especially helpful for speeding up those sites with shared hosting plans)
As you can see, caching provides a number of significant benefits. With so much pressure placed on website owners to serve up the fastest loading websites they can, caching serves as one of the easiest and best ways to meet those demands.
What to Look for in a WordPress Caching Plugin
Before deciding which caching plugin to use on your website, look at what to expect from your caching plugin so that you can make the best decision for your individual needs.
- Ease of Use. Caching plugins vary in their ease of use, particularly when it comes to setup and configuration. Depending on your experience, you may feel comfortable with complex configurations allowing greater amounts of customization, or you may prefer a simpler one-click install.
- If you need additional features, like CDN integration, GZIP compression, and minification, you will want to find a plugin with these features.
- Some plugins have lots of technical support, while others have very little to none. Think about how important accessing a support team is to you.
- Cost always affects buying decisions when choosing a plugin — unless you have a huge budget (lucky you!). Typically, more feature-rich plugins carry a higher price tag. Determine your budget, decide which features you must have, which you would just like, and which you do not need. Then, find a plugin that meets all or as many of these criteria as possible.
In the end, choosing the right caching plugin can be challenging, especially if you do not have a lot of experience assessing them. To make it simpler, here are the most popular caching plugins on the market today.
