Hi Matt,
Good question. You don’t say how long you have had your site up and running – it can take a long time to get to generating traffic from the search engines.
Most of us buy traffic – from pay per click search engines, perhaps some bulk targeted traffic.
Make sure that if you do buy traffic, it is targeted. Otherwise you are wasting your money.
Also, type “search engine optimization” into google or elsewhere and start reading. There is a world of free information out there.
