Article marketing is very well recommended, you just create articles for some directories and they circulate it online, this brings in a lot of exposure and some links to your site.
This is the new article marketing, you can upload some sexy/funny/cool videos on Blip, customize and then add it to YouTube. This can generate mass traffic if your videos are good and make sure they are relevant or else they are of no use.
This won't get you any traffic, but will definitely help you develop some links and it is widely used today by many bloggers. So if you want your comments to be displayed on top subscribe feeds of all sites in your niche and post a comment as soon as there is a new post.
