What’s the cache?
Well, were we to distill WordPress caching into a concise one-liner, it would be this: Effective WordPress caching will make your website faster and more efficient
Research conducted by CDN specialists Akamai found that 49% of consumers expect a page to load in 2 seconds or less. Today, just 51% of users will wait for a website to load, in comparison to 63% just five years ago. In the modern era, people just don’t have the time to wait around for a page to load — it’s the sites with healthier bounce rates that will hook the leads and net new customers.
How does WordPress caching work?
Basically, caching is when regularly accessed website information is stored so that it can be easily retrieved and reused based on previous requests. Since data is exchanged over long distances and often between multiple machines, you need to lower the amount of information that’s exchanged between these devices and the internet. WP Rocket sums it up well:
- A visitor’s web browser will connect with your website’s server when they land on your page.
- WordPress then fetches the relevant information from your database.
- Following this, your web server assembles the data into an HTML page and presents it to the user.
The catch is, WordPress produces content dynamically and displays up-to-date information every time a user lands on your page. So while visitors are being served up the latest information, your WordPress website will take longer to load.
This is where the magic of a WordPress caching plugin comes in!
What is a WordPress Caching Plugin?
WordPress’s PHP scripts are rather cumbersome and can significantly increase your website’s loading times. A WordPress Caching Plugin avoids these issues by creating a static version of your web page to serve up a comparatively lighter HTML page to visitors. This makes all the difference for loading time speed.
The team at Kaira has been designing and developing WordPress websites for over a decade. And in our experience, the following two WordPress Caching Plugins are the cream of the crop.
99% of your website visitors will see static HTML files, which means that just one cached file could potentially be used thousands upon thousands of times. WP Super Cache by Automattic is a leading, innovative WordPress Caching Plugin that serves up cached files in three ways, each being ranked by speed.
1. Expert: WP Super Cache’s quickest method utilises Apache mod_rewrite or the module your web server supports to generate “supercached” static HTML files. It essentially circumvents PHP to make your website significantly quicker. This drastically increases the likelihood of your website performing optimally when it receives an uptick in traffic.
2. Simple: The favoured way of using the plugin (according to the developers). The Simple method allows PHP to serve ‘supercached’ static files to your visitors. This method is almost as quick as the mod_rewrite process, and is simpler to set up and configure because the .htaccess file doesn’t have to be altered.
3. WP-Cache Caching: Primarily used to cache pages for known visitors and URLs with parameters and feeds. As per the developers themselves: “Known users are logged in users, visitors who leave comments or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. WP-Cache caching will also cache visits by unknown users if supercaching is disabled.”
