I find lots of hype and little meat with this topic.
Here's a dose of reality that should make you consider Mobile SEO as critical with your websites.
#1. Click-thru Rates are amazing - IF you are #1 or #2.
According to Google earlier this year, the CTR goes down 90% when you go from #1 to #3.
With "traditional SEO" you will typically see a drop of 50-55%.
For standard SEO the percentage is 50% to 60%
Would love to have an engaging discussion on this topic.
