> How can it be that having intimate knowledge of someone would not allow you to sell them more stuff? John has a 10th wedding anniversary coming up. Mary is single and goes to the gym every day. Steve just got a promotion and likes the BMW 3 series. Michael is overweight but has just gone on a diet. Are such details of no significance determining what ads to show these people?
I think there are a few factors:
1. Targeted ads are more likely to show people things they're already familiar with. The ads are more "expected" so there's less novelty. Untargeted ads can inadvertently hit wants and needs that aren't part of the user's tracking profile.
Closely related to that: targeted ads can induce their own special kind of fatigue. If all you see are diet ads because your profile says you want to lose weight, you're going to get really sick of seeing diet ads. The targeting actually works against effectiveness.
3. Building a good user profile is hard. If you get it right, you have the problems I described in #1. If you get it wrong, you're blasting someone with ads that are completely off the mark (like weight loss ads for a very healthy and fit person).
4. If a user sees one targeted ad a week, that ad is likely to punch above its weight. If they see 50 targeted ads every day, the effect is much different. They're more likely to develop negative emotional reactions to the ads, as they gain awareness and get creeped out by the tracking and attempted manipulation.

2. Targeted ads are much more exploitable by scammers. See: https://www.theatlantic.com/technology/archive/2018/01/the-s.... This leads to a greater erosion of trust. The expense of traditional and untargeted advertising weeds out such scams.
