I'm considering writing an e-book about succeeding in college online, and I want to know more about the potential audience. I already know that this is demographically less affluent, older, more female, and less sophisticated technically than the traditional (on-campus) college student. Key question to be answered: Although this is an audience that numbers in the millions, is it one that I can effectively reach and sell to? Aside from basic data about the size of the audience and its growth rate (past three years historical and next three years projected), I'm most interested in what they do online and where they go -- so that I can see if it's cost-effective to reach them online. What sites do they visit most? How likely are they to buy something online? How much do they spend overall online? How much for digital information products (if known)? How many hours per month are they online? Are there distinct behavioral clusters within the larger cohort? If there is an accessible non-US (but English-speaking) market for this, I would be interested in learning more about that as well.
