Hittail is one of the best things that ever happened to me. I've only been using it for a couple of weeks on the free plan and I was able to quickly identfy an overlooked profit centre on a blog I've run for over 3 years. This month, Jan. 2008, I was already able to make $150 just for my trouble of setting up an affiliate link on a highly trafficed page on that site. In future, I will follow the recommendations that Hittail makes and I'm sure that I will rank well for many more phrases. Thanks alot Hittail...
