I think what nobitu means, he tooks 3 months to build the traffic to get 17000 impression for 4 days.
I don't think this is actually weird, January is typically a bad month, Xmas is over and all the money spent advertising products for Xmas (adwords) is now gone, so we're back to regular advertisers.
my site hsa 35k+ page views but im only earning $20+ a day. T_T. really depends on the keywords and the content of your site.
