This is exactly my point.
Google refuses to give out "precious" information that would help white-hat content providers/e-commerce improve their sites for fear of spammers exploiting that knowledge.
Who do they think they are kidding?!
The spammers are already testing and tweaking at a much faster rate than any Google employee or White-hat site is. If it wasn't so, by defintion, there would be no spam
So instead, the spammers (a smarter bunch than..oh nevermind) who are already on the front lines of "what really works" are always a step ahead of G engineers and at least 2 steps ahead of white-hat sites.
One would assume (this is a VERY BIG assumption) that the algo would give whitehat sites more "quality" points to prevent spam sites from ever ranking, if they had the proper knowledge
But instead, Google plays this silly game of spraying insecticides to kill off the cockroaches in the garden. "And oh oops, we killed off the nice tomatoes that were growing and the cockroaches always come back after a few days, but hey at least we can say we're trying...."
