Mobile Site SEO

Great aggregate information of what to consider when you are creating a mobile website.

I'd add to this in the fact that obtaining the proper optimization is highly dependent upon your ability to
1. Design for Mobile and 2. Measure Well.  Let me clarify...

1. Design for Mobile - This includes not just the organization of content, brief text headings, optimizing for multiple formats... It's about creating a mobile experience containing a user-driven, relevant and easy-to-act-upon UI.  You arent going to be successful at approaching and communicating to your target market without addressing the handsets, not just the iPhone - but many smart phones and web-enabled devices.  

2. Measure Well - bieng that java is not interoperable with over 50% of the Mobile Users on a global basis mainly based upon the existance of so many variables including handsets, browsers (versions and formats), OS, etc. we have a issue with tracking.  You can track user behavior and make adjustments in the wired world much easier, couple browsers, only a few major OS's with a majority of users on Mac/PC platforms... With Mobile Web Analytics, there's a divide on how to best predict user behanvior and optimize websites to drive marketing and performance objectives.  Driving an ad to a cut-out site is going to work, but you can't understand the best way to optimize the site from actionable data streams providing more than gut-feel, argued site layout and content decisions. 

So, that being said, there is a great company lead by Eric Hansen called SiteSpect ( www.sitespect.com ).  They are creating a way for retailers, advertisers and brands to optimize web content based upon user-driven feedback and preferneces - enabling you to showcase relevant and customized content based uppon a myriad of user activities - big surprise, not java driven.  I recommend every performance advertiser and online business to consider the mobile web, not ust becuase you can - throwing up a site to fill the space, but investing in where 30% or more of all internet traffic is coming from - where people are looking for something, not suring, and yes they are willing to transact commerce.  Keep a close eye on the growth of SiteSpect.

Happy Marketing,
James
