Starting last week, Google began sending advertisers personalized thank you messages in video format. The videos are obviously automated and they take almost five minutes to watch but many advertisers are impressed with them.
This is in celebration for AdWords being around for 10 years and Google wanted to thank their customers using something different. You can see the videos at youtube.com/adwords10.
People uploaded their video case studies to Google's YouTube and you can view those testimonials under the explore tab.
Here is a sample of a customized video thank you message from Google.
