Are you part of a social network?
Chances are that most of you are a member of more than one social network, whether it is facebook, myspace, friendster, bebo, orkut, linked in, or otherwise. Social marketing is simply taking advantage of the network you already have, or starting a new network and taking advantage of it.
Here is a list of the top social networks:
There are many ways to get your site exposure through these, but for starters you should add your website to your profile.
Secondly, you can make a post on your space/wall notifying people of your site and/or blog posts. People do mind if you simply are spamming...however if you offer valuable content, your network of friends won't mind. I know for a fact there is nothing more that I dislike than other people spamming me on social networks like Facebook!
Lastly, create a profile/fan page strictly for your WordPress site. Because these pages are typically wide open, any friend that joins or friend of a friend will see this group/fan page. This will lead to some ongoing website traffic...and it is 100% free!
If you already have one or more of these accounts you can utilize them right away.
