Mobile SEO Definition
Jody Nimetz describes Mobile SEO as 'the process of increasing visitors to your web properties through the use of mobile marketing and promotion'.
I am to note that there is the Golden rule of linguistics saying: we cannot describe properties of language in terms of the language. That means Jody says 'Water is wet'.
From my point of view Mobile SEO is a process providing capture of a target mobile audience by optimization (adaptation) in-page / out-page content delivering factors.
End user has to receive exact volume of media which sender sends in terms of content. Mobile SEO is similar to a general SEO we all know, but has very bright distinctive feature - individuality. We can find out what mobile phone brand and model user has, but never of user biography, social status, age, sex, tastes.
For now there is only one mobile marketing tool - SMS or text messaging. But soon situation will be changed.
