When I bought a vacuum on Amazon, I got cross-sells for other vacuums for several weeks. I don’t know how many avid vacuum collectors Amazon studied to conclude that those were the best ads to show me (not a vacuum collector).
Some of that is those advertisers want toeget everyone. You are not a women but odds are you live with one (at some point in life) who asks you to go buy something for her.
I got an offer for life insurance for US veterans - I’m not a US veteran so this has nothing to do with me.
I got an ad for women’s hygiene products, but I’m not a woman. So that’s completely wasted on me.
I just bought a mattress, and I don’t need a 2nd mattress, so all of those are irrelevant.
