With user generated content and the right niche you can get plenty of traffic without SEO or even advertising much. Just find a niche where users want a way to express themselves but cannot currently and then create a site to let them express themselves in that way. One new site I run has been around for only three and a half months and gets between 50,000 and 100,000 page views per day. I haven't advertised it at all, except on two or three forums. The users do all the work of promoting the site because they promote their own content, which also brings other users to the site. I don't write any content for the site either. Everything is user-created. The only bad part is that the niche is low paying, but still I do ok with that type of traffic.

Get traffic from forum discussion..leave your signature and u will get traffic. But the organic way is from SEO
Traffic from DP is probably no what he's looking for since this is posted in the Adsense board (dp users are generally adblind).
