Dear Everyone
I'm looking for a way to drive traffic from social networks but have no idea where should I start at all .
I'm doing good with SEO , but it make me very tired . Anyone can help me start with social ?
I'm having a tool auto in to Pinterest ( all of post from my web will be pin to pinterest ) and I'm thinking about mass follow/unfollow to drive traffic or buy followers .
Please tell me good/bad and any better way and basic of social traffic drive ?

I want to know about this as well.. hope anyone experience can help

I like the idea of using Pinterest. I think that this site has so much to offer. Pin all you can as Pinterest gets so many hits a day that it will be sure to get your site out there.
