I have been doing some research the past couple months, and I couldn't help but notice all the Tumblr blogs out there on the first page of Google. Most of these blogs are blogs specifically built around 1 keyword promoting something free (most notably movies). These blogs have basically no unique content (and little at that, like 1 paragraph) and look flat out spammy, but they somehow are on page 1! One question, how do they manage this? I have yet to really fully get into Tumblr so I don't really have the most experience at it, but my attempts at doing the equivalent with blogger have all failed, so maybe I should try Tumblr?
