Welcome to the new world of mobile SEO. The whole webmaster community is scurrying around in desperation to dominate their niche before the competitors do and we are seeing the biggest mobile SEO gold rush from the adult industry followed up by mainstream acts like game sites, horoscope sites and blogs.
Mobile SEO Not All Bots Are Created Equal
Google uses specialize bots known as Googlebot-Mobile that crawl and index your mobile site based on a whole separate set of algorithms. Furthermore, you can see that Googlebot-Mobile has several different user agents that are tailored to specific phones like Erickson, Iphone and Samsung to name a few. The bots that index the mobile search engine are still in the early stages of development, almost primitive when compared to the main infrastructure. That being said, some of the most important things you can focus on are the old fashion basics like titles, descriptions, titles and heading tags. Some other attributes can be optimized for mobile SEO by using a mobile CSS to make sure the page renders most phones already pull this style sheet except for Iphone so you should definitely create a copy and rename is iphone.css. Other traditional techniques should be used as well. This includes good content, keyword density and a separate mobile sitemap linked to from your robots.txt file.
Off-page SEO for mobile sites is basically the same with a few tweaks and precautions. It is also suggested that you provide dedicated off-page mobile SEO campaigns as to not dilute the efforts of you regular regime. The reason I say this is because your inbound links will be split between similar content or pages on your regular site and the mobile site. (www.m.example.com or www.example.com/m). In addition, You must build up a whole new network of social media and Web2.0 properties that will bring better exposure to these pages. Since most mobile sites have a transcoded version that should be hosted in a temporary subdomain for the mobile search engine so make sure to use a little tag called the “no-transform” cache-control on your regular site and this will help the link to stick.
