I’m sure there are many AdWords who, rather than pause or remove old ads and then add new ones, would much rather just edit ads. Now there is a way you can easily compare all those old ad variations.
To check out the new version history screen, which is only available in he new AdWords interface, just hover next to an ad, click on the pencil icon that appears then select “See version history.”
With version history, you’ll see all the old versions of the ads, along with all the dates that they were edited,, how long they were in place, and what changed. If you want to see the ad’s performance metrics, you’ll need to lick the Columns icon and select the metrics you want to see.
The data can be exported to a spreadsheet.
