Why show four spun pages from the same domain at the top of the serps followed by three of the next domain? It couldn't possibly be to push legit organic results down off the first page now could it? Now why would google want to push organic (free) results off the first page?
i dont think its that. if people search for "football book" and google knows that amazon is the most popular bookshop, it makes much more sense for them to show four football books from amazon at the top, rather than one football book from four different shops.
