It does have a purpose. I found the name of it once, but it’s basically choice confirmation. When you buy something and then shortly after see lots of ads of other people who bought the same thing and are really happy with it/it appears popular, it confirms to you that you made the right choice and should make it again if given the chance. This kind of “confirmation after the fact” advertising is especially used in larger purchases like a car. It reinforces the choice you made in your mind so you feel more satisfied with the brand itself.

except i usually get ads for a thing that’s both more expensive and worse for my use case than the one I bought.
