Need a little help setting eCPM rates

[Mark Bolyard]

Need some help understanding how to set eCPM rates so I can get a set fee per ad location per month. For example, I have a 728x90 banner spot that shows on every page of my site in the header. If I want to earn $100.00 per month for this banner position, how do I determine what to set my eCPM to???

Here are my site's stats:

Based on Google Analytics Data

61,852 Unique Visitors
640,994 Page Views

Based on AWStats Data

60,615 Unique Visitors
3,587,975 Page Views (Never understood why this is always so much more in awstats???)

What I am attempting to do is run Adbrite with Adsense as the alternate when my eCPM isn't met with the Adbrite ads. I don't care about what the eCPM is in Google. What I want to do is replace the google ad content when someone is willing to purchase advertising for that banner spot for $100.00 per month based on those stats above.

Any help would be greatly appreciated. Thank you.

assuming we take the Google number as correct, that's approximately a $0.16 CPM.

just divide the impressions by 1,000, then divide your target revenue ($100) by that number by that number.

So, 640,000 / 1,000 = 640

Then 100 / 640 = $0.16

good luck to you!
