Yep, I also agree that social networks can boost your traffic and if done correctly can boost your online business too..it's a vital piece in my marketing jigsaw... Also try myprivateclassroom.com for some great courses
Its one of the traffic methods that can give you massive traffic. Just watch the top videos on YouTube.com Just see all that 6, 7 digit views!! SocialMarker.com is also great tool you can use.
I have use facebook, myspace and directmatches. I have had some success with all of them. It is a time consuming activity however
What's your industry? I think successful social networking truly depends on the product and whether or not it as inherent "popular" qualities. Also, types of products that are in need of retaining or creating a brand would also work well - and are a must- in social media. It's a great tool to create a personality for a certain product or industry, but also should have some pretty strong interest among the youth and trendsetters..
you can't get more traffic from social networking sites. you can get more traffic from social bookmarking sites.
