Google Adsense has been expanding rapidly lately. It appears that every time I log into my Adsense account, there’s a new feature waiting for me to try. Yesterday was no exception, as a new Adsense for Mobile section showed up. How obvious is this? Pretty obvious in the end. Now you can make a mobile version of your website, and monetize it with optimized mobile Adsense ads.

The Adsense for Mobile ads are pretty straightforward.

When you add the new AdSense for mobile code to your site, we’ll display relevant ads using the same targeting technology that you are familiar with for existing AdSense products.

To get started:
1) Sign in to your account.
2) Select the AdSense Setup tab and click on AdSense for mobile.
3) Follow the instructions to customize your ad unit for AdSense for mobile.

Currently, you can add one ad unit per page to a mobile site that meets Google requirements. I have a few mobile versions laying around to experiment with today. Obviously, as 3G phones take off, more and more people will be surfing the internet using mobile phones, so it makes sense to be able to monetize your mobile pages.
