A great new feature just out in Google search: it now indexes mobile apps as if they were websites! From the horse's mouth, this has just appeared on the Webmasters Central blog: http://googlewebmastercentral.blogspot.com/2013/10/indexing-apps-just-like-websites.html and this feature will become a reality for users in just a few weeks. That's "pretty awsum" if you ask me.
I think it opens up some new doors to anyone marketing/selling mobile apps. Sounds like that niche may have some SEO to do.
Its indeed a great new although there are still a lot of changes or alterations must be made in mobile.
