Care to share what your other means of revenue are? hahaThis is true, but when it comes to google serp; it is hard to classify a mistake as a mistake. That makes the game tougher, I think. For example, you might not be penalised even if you made a mistake. On another blog, you might be penalised for some neg seo that you didn't obviously do to yourself. On a third blog, you might rank for no reason whatsoever. As @VSYNC pointed out, there are no rules. That's pretty hard to digest as a seo/imer. I do not care about it a lot, because I have other revenue streams, but I feel sorry for those who do. No wonder @bartosimpsonio calls google retarded.
