The unfortunate truth is that tracking and individual targeting improves CTR. Advertisers pay for clicks. Until someone comes up with a more profitable metric, they're not going to stop tracking.
Yet the best ads they can show me are for dating sites -- something I am not that interested in, and certainly wouldn't pay for -- and totally ignore all my likes. If marketeers had a single brain cell then the ads on my facebook page would be covered in geeky offers, interesting books, computer hardware, etc.
It is the same with Google. A couple of weeks after I signed the papers for my new appartment I got a ton of ads for the same (crappy) appartment site -- even though I didn't need two appartments, I needed cheap paint and a moving van.
I am considering taking a weekend or so and writing a piece of software that can do it better than the current crop of marketeers, because they are as useless as Dilberts boss.
Are you sure? The vast majority of users are entirely ignorant of tracking, and don't care much even when they do know of it.
