Short answer: The best WordPress caching setup uses one page cache, browser caching for static files and, where useful, a CDN and an object cache. Use only one page caching solution, exclude cart, checkout and account pages, and test your site after each change.

Caching stores ready-made copies of your pages so WordPress does not rebuild them for every visitor. It is one of the biggest speed improvements for most sites.
If you want it set up and tested for you, see my WordPress speed optimization service.
Types of caching
- Page cache: saves the finished HTML of a page
- Browser cache: tells browsers to keep static files such as images and CSS
- Object cache: stores database query results, useful for busy or dynamic sites
- CDN: serves your files from servers closer to the visitor
A simple setup order
- Check if your host already provides page caching. Do not duplicate it.
- If not, choose one caching plugin and turn on page caching.
- Turn on browser caching for static files.
- Add a CDN if your visitors are spread across regions.
- Consider object caching for large or dynamic sites, if your host supports it.
- Clear the cache and test the pages again.
Pages to exclude
Do not cache pages that are different for each user: cart, checkout, account pages and anything with personal data. Many tools exclude the standard shop pages automatically, but check.
Common mistakes
- Running two page caching plugins
- Caching cart and checkout pages
- Forgetting to clear the cache after design changes
- Combining and minifying files without testing, which can break layouts

FAQ
Do I need a caching plugin if my host has caching?
Often not for page caching. Check what your host provides first.
Will caching fix a slow server?
It helps a lot, but a very slow host still limits results.
How do I know caching works?
Test in a private window and check your page speed results before and after.
