The question for me is: what motive or what result does Google have an interest in? Are they simply cleaning up the index? Or is it becoming strictly an ad issue? Almost every time they've done some kind of clean up, this is what happens. After they identify the items that need to be removed or purged, things go back to normal. Until that happens, the search results become as you describe, all messed up with original content suffering while copied garbage reults rule the day. It may be the method they need to administer to bring bad results to the front and then they can be dealt with. I don't know. I don't think it's to steer people to ads alone, if that were the case then the entire search engine is nothing more than one big ad. If they HAVE done that as a strategy, they are no longer what they once were in spirit, a search engine to get unbiased machine based results. All search engines are guilty of this to some degree, the simplicity of search is gone. It's all about money, but if that is the motive, then it won't be a good search engine anymore, ready for someone to replace it with a better search. There needs to be a balance between serving the shareholder and serving the public, and I personally believe when you serve the public as best you can, then shareholders will be happy too without manipulation.
