I don't have a problem with the theory of targeted ads, in fact as a consumer it is actually useful. If you start looking for a pair of boots, then see that a brand you like but was out of your budget has a sale on, so you buy those boots you really wanted but couldn't afford. That's useful for a consumer. The problem is that targeted advertising mostly just sucks. Last year I bought wireless headphones from Amazon, and everyone I visited them again for the next two weeks I had recommendations to buy wireless headphones. So even Amazon can't do it properly. What if I'd browsed on Amazon and bought from another store? The other day I saw an ad on twitter for an wine company, in the "why am I seeing this as?" section it said that it is targeted to males (yup), aged 35 and above (no) who live in the United Kingdom (no). And to top it off, I don't even drink. The problem is targeted ads mostly don't work, their targeting is so simplistic (see something you like, then blast you with ads for that over and over) or just assign you to such a general bucket (age range and location) that it isn't useful. Even "likes" aren't that useful for targeting - just because I "like" a brand doesn't mean I want to be blasted with ads from them or am going to buy every product they sell. I like Thinkpads, but that doesn't mean I'm going to buy every new ThinkPad that is released.
