As Sumner Redstone rightly said, “Content is King.” This little phrase is the first thing you learn about SEO, and has been awarded more articles than any other topic on the Internet.

Social media has been buzzing along for several years now, and with Facebook at 400 million registered users, and Twitter at 105 million registered users , it's ridiculous to ignore the two. Both services are free, and great tools to directly interact with your customers. I've outlined how to optimize your site, e-mail, and print campaigns for Facebook and Twitter.

At the Web 2.0 Summit, Bing announced its newly acquired search deal with Twitter and Facebook to provide real-time social results through its search engine.  Google immediately fired back by carrying out its own deal with Twitter, and launching the new Social Search feature. 

Contrary to what you might think, there aren't many direct technical SEO benefits from using Twitter:

What is an infographic or information graphic?

As defined by wikipedia, infographics are visual representations of information, data or knowledge. These graphics are used where complex information needs to be explained quickly and clearly, such as in signs, maps, journalism,  technical writing, and education. They are also used extensively as tools by computer scientists,mathematicians, and statisticians to ease the process of developing and communicating conceptual information.

As you know Twitter has taken the web by storm with a traffic rate increase going from roughly 1 million to 20 million unique visitors just in the last year. (Compete.com)

Social Media sites like Digg, Reddit, Stumbleupon, and Delicious are highly authoritative sites which can dramatically improve search engine rankings if used properly.  Any SEO specialist knows link building is essential to improving search engine visibility, but some clients have trouble accepting social media as a link building tactic.  

Most new Digg users are baffled with the amount of information and resources that exists on how to get to the front page of Digg. I've read many articles suggesting that adding thousands of friends, submitting hundreds of stories per month, or simply going on a digg and commenting rampage will help you get to the front page. As you may have found out, none of these strategies work when trying to build an authoritative profile on Digg or getting stories on the front page.

Within the last 3 years Social Networks have taken the internet by storm. Startups have created enormous communities bringing millions of people together through user-friendly interfaces and applications. User's can create profiles and share pictures, music, friends, comments, personal information, favorite sites, and much more. Social Networks like Myspace.com, and Facebook.com have grown at exponential rates and continue to grow.
