Once a campaign is deleted, it cannot be restored to active status. If you delete a campaign, its ads are no longer active, but you can view the campaign (and all its ad groups, etc.) as it was when it was deleted for up to 90 days. You cannot restart a campaign that has been deleted. Deleted campaigns do not count against the campaign limit for your account.

Rather than deleting a campaign, consider pausing it.

To delete a campaign:

1. Click the Campaigns tab.
2. Place a check mark next to the campaign or campaigns you wish to delete.
3. Click the Delete button at the top of the list of campaigns to delete all selected campaigns.
