My traffic is getting better each and every week (it does take time). I have found that by writing about an interesting topic (or at least a well searched topic) with a good title is the best way for traffic. Google alone accounts for 60% of my traffic and I have 2 hubs that are listed #1 for their respective keywords. I also use the standard social media sites, (FB, Twiiter, Digg, Stumble, and Pinterst) and certain forums but I find that they only give me a short, mild boost if best. I have heard recipe hubs do well on here, let me know how they work for you.
