I am currently getting decent traffic from Pinterest. I am still new to it all and learning it. What I have learned so far is this: Make boards relevant to your sites interests, if your using Pinterest for your website. Each time you find something on the web relevant to your topics OR make your own blog post at your site Pin it! Do it often and watch it grow. I just keep my boards cleaned up and fresh, with neat stuff that is relevant to my niche. I sit back and folks just keep pinning my stuff and when they like it some follow me. So its growing fast! Pinterest rocks! I can't wait to hear others advice on the topic who have been at it longer.
