Google is very keen on mobile, it's been working on building mobile alternatives for all of its products and is already seeing quite a lot money coming from mobile ads. No surprise then that it wants everyone to keep up and build mobile sites that its Android phones can use and its advertising can reach.

There's not much to go on, but the focus of the site clearly seems to be on optimizing for mobile use. Google already offers a way of catering to mobile users via the Google Mobile Optimizer in the Webmaster Tools, but that comes with a very limited set of options and capabilities.

Google already has experience converting sites for mobile use, granted, only those it hosts itself via Blogger and Sites.
Google debuted a set of mobile-optimized templates

It went further with Sites, it automatically converts the user created websites into mobile friendly ones. It later introduced a way of creating a mobile version of your site
in the same WYSIWYG editor that Sites uses.
