Adsense for mobile websites

What exactly *is* a mobile website?

[alkuma]

Hi folks,
Do any of you use adsense for mobiles?
I'm curious to know what a "for mobile" website is. My website's pages are XHTML 1.0 Strict compliant.
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"

Is that enough to make a website "for mobile"?
I guess not, because if that was the case, they wouldn't have called them "for mobile" sites, just xhtml 1.0 strict compliant.

I understand that apart from standard compliance(which ones?), there are some elements of style that need to be taken care of. Any pointers to both the standards and style would be appreciated.

Additionally, one ad per "mobile website" page is allowed, while 8 units are allowed on a regular website. Does this imply that google assumes that the mobile version and the non mobile versions would be different from each other? Or does google expect the webmaster to figure out via server side scripting if the user is a mobile user or a regular user?

Strictly speaking, no, check these links:

Additionally, one ad per "mobile website" page is allowed, while 8 units are allowed on a regular website.

8 units on a mobile screen...!
