Can someone explain to me how an advertising network finds out how much traffic your site gets? My blog is currently getting over 11,000 impressions a month which is higher than the minimum that a lot of networks demand but they are rejecting me for not getting enough impressions. Chitika for example just rejected me for not meeting their 10,000 a month impression requirement.
i'm sure they wouldn't take time out to say; alexa ranking is pretty bad for determining traffic. one site i know of gets over 200k vistors/day, and ranks at around 1300 alexa. another gets about 135k/day and is ranked at about 550.
I don't think they can find out. At the end of the day it's your stats that are private to you and therefore they can't see them. Maybe it's just because you are boarder line to that network that declined you.
They probably go by alexa ranking and some other sites like Quantcast etc which are all wrong. You can look up any site's traffic here http://www.statsaholic.com/ It shows my site had 7000 visitors in Nov and less than 4000 in Dec, whereas in reality I had 30K in Nov and 8K in Dec. See the disparity?
Its difficult to say. I guess they probably go with people's words and look at how good the content is to determine quality.
