The new interface and Adwords Editor get really confusing with hundreds of paused campaigns, thousands of paused keywords and hundreds of paused ads. How do you manage the clutter? I'm looking for a system that works without forever losing data.
It's a work around, but it works for me....
Also they are never really deleted entirely (you can still download them in Adwords Editor), and they can be resumed if needed. But you should have everything you need in the Reports.
If you wanted, you could export to CSV from Editor, then delete them. So you had the structure archived as well.
