I intend to sell small banner ads as well as job ads on my site. The job ads I'm less worried about because I can look at similar publications, get their rate cards and price myself according to my traffic. I have no idea on where to even begin pricing banner ad spots.
I have read about some of the terms, but whenever I try to find numbers, real numbers not just % change over the last year, the author is usually trying to sell me their service.
Where can I find objective data and information for how to price banner ads?
My inclination is to go by Page Views which I think translates to CPM?
