What is a cache?
In order to reduce this time, the server uses what is known as the cache. Instead of loading dynamic objects from scratch each time and calling them from the database, a static version of the site is stored in the cache. The user, therefore, receives a finished website, which may not be the most recent version but loads significantly faster. This is exactly what a WordPress caching plug-in can help you with.
IONOS WordPress hosting uses SSD technology to save installations and related databases. This can give your website a 50% faster response time.
What do you need a WordPress caching plug-in for?
Caching generally has a lot of advantages and is always useful to have. Depending on your hosting solution, the service provider might already handle caching at the server level, meaning you have nothing to worry about. This is especially helpful if you have no technical knowledge on the subject.
If you have a shared hosting solution or you host your own WordPress website on your own server, a WordPress caching plug-in is a sensible idea.
Advantages of WordPress caching plug-ins
- Faster loading time: Since you save data and other objects in the cache, the browser can load your website more quickly.
- Better user experience: A fast-loading website is more inviting for users and will reduce the quit rate.
- Less server resources: WordPress caching plug-ins relieve the server, as it has to handle fewer requests.
- Better search engine optimization: Thanks to the quicker loading time and better user experience, your website will be ranked more highly by search engines.
- Lower “time to first byte” (TTFB): TTFB is a measurement of the responsiveness of a server. This is the time the server needs to be able to send the first byte of data to the browser. You can reduce this time by using a WordPress caching plug-in.
Disadvantages of WordPress caching plug-ins
Depending on the things you want to display on your website and how often you change your content, WordPress caching plug-ins can have the following disadvantages:
- Basic knowledge requirements: Unlike caching at the server level, WordPress caching plug-ins require basic knowledge for you to be able to optimize the plug-in for your own website and make sure that everything displays correctly in the end.
- Constantly changing information: If, for example, you show the number of active readers on your site, a browser using caching techniques will always show the older, saved version. The latest data will only be shown once the cache has been cleared.
- Old prices on affiliated websites: Affiliated websites show the prices of products in other online stores. If these stores change their prices, the browser will only show these new prices once the cache has been cleared. To avoid outdated prices being shown on your website, it is recommended that you set it up so that affiliated websites are automatically deleted from your cache after one to two hours.
When you make any changes or updates to your website, you should immediately clear your WordPress cache. The browser will then directly show the page’s new content.
WordPress caching plug-ins: the most important features
WordPress caching plug-ins offer a range of different features to help improve the loading times of your website. The most important features to speed up your WordPress website are as follows:
- Combining files: Websites often use various CSS and JS files. Each file needs its own request. In order to reduce the number of requests, the plug-in bundles individual CSS and JS files into one bulk file.
- Browser caching: When a user visits a site, the plug-in creates copies of the various resources. If the user visits the same site again, these resources are taken directly from the cache.
- GZip compression: WordPress caching plug-ins can use Gzip to reduce the size of HTML, CSS and JS files.
- CDN (Content Delivery Network): Data can be sent more quickly over a CDN.
- Image optimization: Large images or a lot of images often slow the loading times of a website. Optimized image sizes noticeably improve performance.

WP Fastest Cache
WP Fastest Cache has over a million active installations, making it one of the most popular WordPress caching plug-ins. It is very easy to use and comes with a whole host of different settings that you can turn on and off using checkboxes.

W3 Total Cache
W3 Total Cache is completely free. There is no premium or paid version to unlock any features. All important features are already available in the base version. The extensive range of features makes this WordPress caching plug-in a little more complicated to use for beginners. If you already have a little knowledge, this is a good choice to get access to a bunch of fine-tuning possibilities absolutely free.
Pros and cons of W3 Total Cache

WP Super Cache
WP Super Cache, however, is easier to use than W3 Total Cache. The caching modes are particularly helpful. Beginners can use the simple mode to get effective caching without taking risks. If you want more in‑depth options, there’s also an expert mode that lets you use more precise settings. However, you need to have enough technical expertise to be able to use this mode safely, as it affects important server files.
The WP Super Cache plug-in was developed by the same company that developed WordPress. WordPress users therefore think of it as the official WordPress caching plug-in. The biggest advantage of this plug-in is that it sets up static HTML pages. This allows the browser to display the site significantly faster than when reading data from a database.
Pros and cons of the WordPress caching plug-in WP Super Cache
|Three modes for quicker installation||No Google Fonts optimization|
|Sets up static HTML sites||No lazy load option|
|GZip compression||No option to minimize or combine individual CSS or JS files|
