A crawler is a bot that moves around your site and refreshes pages to create cached pages before a visitor does.
If the first visitor visits your page, he initiates caching and the page is loaded a little slower for him, but that's why the cached version is loaded quickly for each subsequent visitor.
The crawler allows the cache to be created earlier before the visit.
Keep in mind that as good as this can be, it can also be harmful because it simulates visits and can put a load on your account. So be careful about using this option.
To start, click Manually run. We will not deal with the other options because we believe that this can cause more load on the account, something is really needed. This can only be useful if the site is small so it won't affect the load much. For shops, this is definitely not recommended.
