As more and more people are utilizing their mobile phones to access web content on a daily basis, more and more publishers are looking for ways to monetize that area better. A WebmasterWorld thread has several Google AdSense publishers discussing tactics, strategies and stories on what they did to help monetize their site's with Google AdSense mobile ads.
Most of these publishers are sticking to monetizing for full-size mobile browsers, such as iPhones, Android devices, Palm Pre and some Blackberries. While others are also looking to monetize for WAP based browsers, which support less features but do render content specially formatted for those non-full-size mobile browsers.
Personally, I don't bother with WAP, I go for full size browsers, such as those found on iPhones, Android devices, Palm Pre and some Blackberries. Why? Simply because those with those types of devices are consuming the mobile web at a much higher rate than those without those devices.
I shouldn't probably talk, since this site isn't really mobile friendly. But discuss techniques on this over here on some level.
