You're listing interests... Using that just reminds people of their desires. John has a 10y anniversary - will make John focused in buying stuff, he'll need exposure to new products... Not ads for stuff that he already looked at. John is probably not an amnesiac. Mary is single and likes gym - doesn't make her more interested in gym clothes, she's already well aware of the gym clothes... Steve getting a promo bundled with him liking BMW will be a total waste of a ad target. He already knows the cars and will buy a BMW with or without an ad from any car manufacturer. Going on a diet implies that you know what diet you're going on. In short retargeting is great at reminding people of what they like. It's really not great at acquiring new customers. I worked on this stuff and it's flashy, but ultimately just a great way to siphon off marketing budgets out of corporations. Don't sell your stock just yet. The product is useless, but it's a scam that is as prevalent as organized religion
