That is my definition of perfect targeting. And it also explains why Google wants to get more information out of us. Obviously more information means better targeting. But this better targeting also means better ads that are more relevant. Relevant doesn't mean ads close to what I want but not really what I want. Relevant means genuinely relevant. And I REALLY believe Google is trying to achieve that perfect genuine relevancy.
Sure Good search results are there, but there is still noise. Good search results still requires us wafting through the crap. But with paid well targeted ads, the right information has the potential to come to you by circumventing the things that cause the noise. Companies who know they have an advantage on pervert night vision goggles can pay for that highly targeted area and get the information to the right people.
