Time to Go for 'Mobile SEO'?
As Meunier notes, "mobile search behavior differs from desktop search behavior in frequency, category, and intent." Therefore, he adds:
With the understanding that mobile searches are searching differently, the easiest, most effective way for a webmaster to make her site relevant to mobile searchers is to create mobile-specific content that is tightly-themed for relevant mobile searches. Its not absolutely necessary at this point, but it could make a site more competitive for mobile searches than a site that doesnt consider the mobile user experience.
So mobile SEO isn't dead yet, not by a long shot, it seems.
How will mobile SEO be measured? Organizations that track searches will have to be able to tell which queries come from which devices, and the content will need to be tailored to mobile searchers.
