I thought I would put a tips thread up to see when your Adwords accounts had a "Breakthrough" and what it was you did to achieve it. Also, please let us know how your account changed after you implemented this change. I've never really been a huge fan of Adcenter, but when the Beta was released (beta.adcenter.microsoft.com) it really made the interface easier to use and also organized the geo-targeting by state instead of alphabetically. Kudos Beta Adcenter.
I guess alot of people do, but the truth is that he huge success is happening at MSN, but I can be wrong.
So what is something you've done in adcenter that has made a difference. a tweak to your campaigns so to speak.
