Using the form below, you can view creative (graphics, e.g. JPG files, Animated GIF and Flash) Banner Ads that are currently launched and active in Google AdWords/AdSense via DoubleClick... this maybe a glitch, or may not work for very long. I discovered it by accident. I'm not sure if it's an easter egg or an internal tool for Google staff.
Enter a group of key phrases and press Show Me. A box will appear below with an AdWords Image Ad (a banner running on the content network) related to your keyword. What's bizarre is that it is almost identical to the Google's Search Sponsored Listings tool, but that one doesn't show any banner creative. To see a different ad, submit the form again.
If this form stops working, email me.
