But how can you leverage the broad reach and basic principles of social media  to enhance your SEO efforts? 
The trick is to think of social media marketing as fundamentally different from SEO. You’re going to get off on the wrong foot if you think of social media optimisation as link building.

It’s more about enhancing your brand, spreading the word and engaging with people.

Companies often approach Social Computing as a list of technologies to be deployed as needed — a blog here, a community there — to achieve a marketing goal.

But a more coherent approach is to start with your target audience and determine what kind of relationship you want to build with them, based on what they are ready for.

Know who you are selling information to…

The main point is to think conversationally. These are called social networking sites because their purpose is to connect peers and create networks. They can be business networks, but if you try to make your social networking content all about your business, you’re not likely to generate much interest from your peers.

So, be conversational in your tone. Get friends. Get business colleagues. Network. Have conversations. Share your friends’ links on your site. Re-tweet links from your followers, and they’re more likely to share your links.

So, with social media, keep it real, get creative, be honest and you’re more likely to succeed.
