The tool is called My Change History and it is fantastic! This tool allows you to go 3 months in the past and view all of the changes you have performed on your account including adding/deleting keywords, accepting new terms and conditions, updating
budget delivery methods, activating and deleting campaigns, changing CPC's, adding and removing text and banner ads, and creating new campaigns.What I like about creating new campaigns is being able to see all of the initial settings. In this post is a picture of an ad I created recently and the initial settings. Over the next hour I added and adjusted the ad, and all of that is recorded as well.
My Change History is great because it stops time for a brief moment to allow you to see what went wrong, or what went right!
