I guess we're missing this in the google faqs. Where do we delete campaigns so that they no longer appear in the list of campaigns? Right now they remain as "deleted". We're just trying to tidy up the main page, these were 1 day tests to compare against the validity of the google search average reports. Thanks
You can't completely delete old campaigns, as Google uses them. For example, if you delete an old campaign and create a new, identical one, Google will remember the old data so that you can't use this to keep your Quality Score artificially high. But you have the option to only show active campaigns (on the right, above the top campaign). This should allow you to keep things tidy.
You can cut and paste them from one account to another, but they will still show in your list as "deleted". Just use the "view active" link and you'll never see them.
