WordPress Caching Explained
Caching stores reusable results so WordPress does not repeat expensive work for every request.
Page cache
Stores rendered HTML for requests that can safely share the same output.
Object cache
Stores results from expensive application/database operations; Redis is a common implementation.
Browser cache
Lets returning visitors reuse static assets locally.
CDN cache
Stores cacheable content at edge locations closer to visitors.
Caution
Dynamic ecommerce/account pages need correct exclusions to avoid serving personalized content to the wrong visitor.
If hosting is part of the bottleneck
Compare managed WordPress hosting after you have evidence that infrastructure or support scope is limiting the site. Start with our managed WordPress hosting guide or see our WPX review.
