The cache in short: It stores a ready-made version of your page in advance, so the visitor doesn't have to load everything from scratch every time, but gets the faster "pre-cooked" version.
What is caching?
A cache is a memory that temporarily stores certain parts of your page so that it loads faster the next time.
If there is no cache, WordPress will re-retrieve the database on every visit, load the template and plugins, and then compile the entire page.
It's like cooking dinner from scratch every time. Cache, on the other hand, is like having it prepared in advance and just taking it out of the fridge.
How does caching help?
- It provides faster loading because you don't have to rerun everything every time.
- It provides a better user experience, as visitors don't have to wait long seconds.
- Google favors fast pages, so it's also beneficial from an SEO perspective.
- It reduces server load, so the same hosting can handle more visitors.
Cache types
- Browser cache – images, CSS and JS files are stored on the user's computer.
- Server-side cache – the hosting provider saves frequently used data.
- Page cache – the entire page is saved as finished HTML.
- Object cache – stores database queries.
- CDN cache – if you use a CDN, your page is stored in multiple locations around the world.
What should you pay attention to when using cache?
- If your page is not updating (for example, the old version is displayed even after a new post, product, or image), you need to clear the cache.
- With WooCommerce web stores, you need to make sure that the cart and payment page are not cached, otherwise there may be problems with the purchase.
- If there are multiple cache layers (plugins, hosting, CDN), you will need to flush them all when you make changes.
Recommended cache plugins
- LiteSpeed Cache – if you have a LiteSpeed server, this is one of the best.
- WP Rocket – paid, but very effective and beginner-friendly.
- W3 Total Cache – professional settings options, but a little more complicated.
- WP Super Cache – simple and easy to use.
