I know it sounds and actually is stupid. I am trying to promote my app with AdMob. In the promotion form there, I put

 URL: market://details?id=com.xxxx.xxxxxx.xxxxx
 DisplayUrl: ????

Whatever I enter for DisplayUrl, system is giving me invalid format error.

I have read the guidelines http://helpcenter.admob.com/content/content-guidelines#displayURL but it does not help at all. Can someone help me?

UPDATE: I fed up with that option Text & Tile and went with image option with which I can upload my own image and be done with it. So much for 1 cent/click saved.
