You might be concerned that your cached web pages will become outdated as you update your website. That is a potential danger.
This is handled by setting an expiration date for cached pages. Once a cached plugin is out-of-date, it will be rebuilt automatically from the database the next time someone visits it.
If your website content changes often, then it is best to set a shorter expiry date. For websites with few changes, you can set a longer expiry date.
You can also manually clear your WordPress cache to make sure that your visitors are seeing your latest updates. You can learn how to do this for several popular caching plugins and hosting providers in our guide on how to clear your cache in WordPress.
