You can view and manage all of your existing ads from the Ad Manager. You can access your ad manager through the dropdown underneath your username in the top navigation. Open the dropdown and click on "Advertising".
You are now viewing your ad manager where you can edit or delete existing ads as well as view more information about them.
To delete an ad you must first ensure that it is not currently in use on any pages. This prevents you from inadvertently removing ads that you are still using. You can view all of the pages where an ad is used by clicking on the Pages button for each ad in the manager. This will open a more detailed page for that particular ad , and will include a list of all the pages where the ad is displayed and options to view or remove the ad from those pages. Once you have removed the ad from all pages it can be deleted. When an ad is removed from a page charges for that ad space stop accruing.
