I'm apparently a 25-34-year-old male, at least according to Google. I don't like age-gender stereotypes: I have some interests which would not match that age group, and have some interests that do not match that gender. I'd guess the same thing applies to most other people as well. Perhaps we need to get marketers to move from demographic classifications to an interest-based targeting system? It would be more successful, and better received (at least by consumers like me).
Hey ladies, does Google think you’re a guy?
I’m the lady in the orange dress.
