My friend Peter Papadimitriou at Globecraft sent me the following email he received from Google:
Dear Peter Papadimitriou,
We are happy to announce a new feature that will allow you to
easily reach additional qualified customers who are searching
Google from their mobile phones.
In the next few days, your search ads will be eligible to run on
Google Mobile Search pages (like they currently do on Google.com).
We are offering this feature – and any resulting clicks – for
free through November 18, so you can experiment with the rapidly
growing mobile platform while still reaching qualified customers.
