Maile Ohye, a Google developer lead who has worked on mobile and webmaster topics for a long time, shared on Google+ that she was fed up.
Well, fed up with seeing "so many bad mobile websites" that she decided to do something about it. What did she do? She published documentation in the form of videos and a check list named Checklist for mobile website improvement.
Maile said, "A girl can only take so many bad mobile websites before she's compelled to publish documentation."
The document goes through both technical issues, marketing issues and conversion issues related to mobile web sites.
Mobile, as you all know, is increasingly important these days. So you should spend the time reading this resource.
