What I'm thinking about... and wondering if anybody had any experience, but do websites that target older people have a better click rates then say computer geeeks or college students? Does anybody have a grandma/grandpa site where they run adsense? or some other sites that are different from the normal "gadget" and "tech" sites?
I remember reading about this somewhere else on the forums that in fact sites targeted for older users do see higher CTR's. I think kids and teens have never seen an internet without Adwords or other ad formats and as such have become oblivious to them, while older folks may just be starting out their internet experiences so they may be more likely to click on anything that looks like an interesting link.
