Its all those dummy search pages with the paid Yahoo the Google search listings on them. We have to assume that there are website owners of these, a small minority of which click on some of the top links every once in awhile to get a commission. If they all did this it would ad up to a fortune. If they did it once a day their click would register as a valid one.
