Frequently Asked Questions

Do I need a caching plugin if my host provides caching?

While hosting-level caching is valuable, a caching plugin can provide additional optimization features and finer control over caching behavior.

Can I use multiple caching plugins?

No, using multiple caching plugins is not recommended as they can conflict with each other and potentially cause site issues.

Will a performance plugin fix all my speed issues?

No, while performance plugins can significantly improve load times, other factors like hosting quality, theme optimization, and image sizes also play crucial roles.

How often should I clear my cache?

It's recommended to clear cache after making significant changes to your website, such as updating themes, plugins, or content. Some plugins can do this automatically.

What's the difference between page caching and browser caching?

Page caching stores static versions of your pages on the server, while browser caching tells visitors' browsers to store certain files locally for faster subsequent visits.
