What did I misunderstand?
Isn't this a complete set up by Google? They know how clickstream data works.
As I understand from the original story they had their own guys opt in to the Bing clickstream feedback thing, they searched repeatedly on nonsensical terms and then clicked on the same link each time after searching.
Later, they enter the term in to Bing and the only matches that it has are the clickstream data that says "when people searched for this term they then clicked on this link". So that link is displayed as the search result?
So is this not them opting in to another companies "improve our results" program, sending poisoned results back, and then complaining that the poisoned results were displayed?
Wouldn't this work for "strings no one is ever going to search on" with any automated feedback system?
