Anybody notice the sponsored ads on some searches. (see below) Before you know it, all of Google first page results for search queries will be based upon revenue. We have Adwords and now Google sponsored listings before organic. Could it be that one day all first page results will be revenue generating in some way for G. Think about it, all they would have to do is implement some type of auction type of listing that is cheaper than Adwords. You start paying a per click cost (cheaper than Adwords) to have a certain position. Funds dry up or you get out bid and you lose your position and/or 1st page ranking.
