Im gonna start running a series of polls on my website so I can get a much better idea of what type of students exactly use my website. I've got polls running asking them about what they plan on doing after high school, what extracurriculars they're involved in, what grades they get, their class rank, how many AP classes they are taking as well as the standard age, gender, household size, household income, etc.

I'm trying to think what information would matter if I was pitching out to a potential advertiser. Any ideas?
