Mine is currently from blogs and other internet marketing forums. What are you guys top traffic source?
Google, forums, Twitter and G+. I create web 2.0 sites for SEO and they all bring me in a good deal of visitors per month.
No I am talking about creating relevant niche sites through Weebly, Tumblr, Blogger, Webs.com, etc. I usually put 5-10 articles on them and some of them will bring in traffic, but I do this on a large scale so it adds up over time. What I have found is that these visitors are highly targeted as they read an article from the Web 2.0 site and clicked a link to find the site, so they know what they are looking for from the start. This is a great way to get traffic for eCommerce websites!
Sorry I don't share this information. A dozen of them is usually enough to get some traffic, but either way, it's good SEO and looks natural if you do it right. I link to authority sites in all the posts, and then just one or two posts will include a link to the money site. This method sucks if you spin articles or use low quality content, so do it right the first time.
