Internet Marketing - Social Network

Social Networks, like Myspace, Facebook, etc. are a great way to get your ideas and products in front of a lot of eyeballs.
Most (if not all) of these places allow you to create a profile? that people will see. Inside that profile, you can (carefully) direct your traffic to either you main sites or directly to your products Paid Social Network Site
I would suggest that you interact with the networks and gently push your traffic to your main sites products.
Otherwise, you will get a reputation as a spammer and your profile deleted. So, be careful!!
