> There is a growing group of people who are increasingly doubtful of this Most targeted advertising, sure. Targeted ads based on interests? Diet? General age range? Of course those will be more effective. Showing me targeted ads for fitness products has been very effective, I have a yoga and a workout app I use that are both 100% due to targeted ads. I also have tried out various food products (keto cereal!) due to targeted ads. Interest based ads work, if done well. Now that said, ads for stuff I already bought, eh, less so. Even worse if I buy something from an ad, get it home, unbox it, then google for help. Now I get ads trying to sell me the same product again. Though I'm not sure how horribly invasive ads would have to be to avoid that scenario. I've generally found FB ads to be, honestly, useful at times. What I really don't trust are kickstarter campaigns running YT ads. Shouts 'scam!' to me almost instantly. Also that YT ad that was playing a few months ago for the $20 adjustable dumbbell set that went to a super shady site. (Normally adjustable dumbbells go for $500+...) It appeared to be a fake storefront, but YT kept happily running the ad day after day. It was well targeted though. :)
