If you have a mobile website, you have just gotten a new way to monetize your site today, as Google has made Adsense for Mobile to its publishers.
To use Adsense For Mobile, your site needs to be in wml, xhtml, or ctml. You can put one mobile ad unit on each page, and each unit can contain one (single) or two (double) ads. You can also customize your color scheme and select a channel to track, just like Adsense for Content. Adsnese For Mobile requires server-side scripting, and at this moment the following languages are supported:
PHP v4.3.0 or greater
Perl v5.8 or greater
JSP v1.2 or greater
ASP v3.0 or greater
