Archive inactive campaigns, ad groups, and ads to reduce clutter and decrease load time when using Ads Manager.
You can archive using the Ads Manager or bulk editor. In Ads Manager, you can archive the same way you make edits. With the bulk editor, you can archive multiple campaigns, ad groups or ads at a time by specifying ‘ARCHIVE’ in the action column.
Archiving a campaign or an ad group will also archive everything within it. For example, if you archive a campaign, all ad groups and ads in that campaign will be archived. If you archive an ad group, the ads will be archived, but the campaign and any other ad groups in that campaign will not be affected.
Once something has been archived, it can't be restored. Archiving will permanently remove a component from your default views and reports. While you can't undo this action, you can still export performance data on archived objects.
