Did you know that you should be deactivate content in AEM before deleting them?
Yes, it's true! The content (even though deleted from AEM) could still be visible on Google Search or on cached versions of the site for a while.
In the event that you no longer need a web page, we recommend that you use the Deactivate Page option rather than the Delete Page option. Pages cannot be recovered once they are deleted.
However, if you are sure that you would like to delete a page, deactivate first before deleting. It's important to deactivate pages and PDFs from the AEM system before you select to delete.
If you are working in the Site Admin view, simply select the content and click Deactivate at the top before deleting.
