try to write very very hillarious article and then link the article to your site and then submit to fark.com and be prepared to be bombared with ton and ton of traffics, work to me before!
try to bring traffic from twitter. but it may bring average 100-200 visitor per day per twitter account.
To recieve the most traffic and free is from the organic search so use an seo company to help your site reach the top
