Agree with you that IRL it’s more complicated than just 3 points but am writing this for an audience of developers and tech folk so figured simplicity was more important than exhaustiveness but is otherwise generally accurate as a high level mental model. As for the straight up demographics example I called out I think that would work ok in theory but suffers from the major problem that you can not accurately identify that audience group to begin with and often doing so gets into the sleezier side of marketing that I personally want nothing to do with if I can avoid it. On top of that, I think there are better approaches, women 18-24 are not one homogeneous group with the same wants and needs and treating them that way might work better than the idea of let’s just show the same message to everyone all the time but I hardly think it’s the pinnacle of tailoring your content either.
