have you tried twitter or yahoo answers? Maybe even making a youtube video? Not sure but it may bring you some traffic for free.
Doing Twitter and Yahoo Answers at the moment. Haven't made a youtube video yet.
Yahoo usually spikes my traffic and then dies.
I'm averaging 100 visitors a day from search engines and backlinks alone so thats good. I expect it to rise slowly over the coming months. My niche has very high competition so I'm trying to use a variety of keyword and keyword phrases.
