If anyone who might read this wonders how to get more traffic to your site, what ever it may be, you are in the right spot.  THE best place to get traffic, and pretty good targeted traffic, for FREE, is Stumbleupon.com

There is a trick to doing it though.  Let’s say you have a general adsense site, about aquarium fish.  You get some good traffic because you have been doing seo for awhile, and maybe some ppc.  But you want a boost in your traffic.  So here’s what you do:

1. Login to forums.digitalpoint.com (if you don’t have an account, sign up for one)
2.  Go to the “freebies” forum area.
3. Look for people who post something like “Stumble my 2, I’ll stumble all yours”
4. Go in and stumble their site (aka : give it a thumbs up)
5. Post your urls, and who ever started the thread will stumble your site

You want to go in and review all of your own sites, and try and get others to review your site as well.  Reviewing a site on Stumbleupon gives you a do-follow link from a PR2-5 page on stumbleupon.  My own stumble page is torkildson.stumbleupon.com, you can add me as a friend.
