Right AdServer which can meet my requirements?

I am looking for an ad server which can fit my special requirements.
I have a network of 1000s sites, I am serving the same ad on multiple (100s) of sites.
1) We need to be able to set up the campaigns easily and quickly (minimum data entry)
2) We need to be able to geo-target the ads (Our site network is worldwide) and get a report with geo-targeting features.
3) We need to track the impressions of each ad per website/url and get a report. The report must give us an impression breakdown per website and per ad (in real-time).
(again here, with minimum data entry. I don't want to have to create 100 channels, zones, websites manually).


it is essential for me to have an impression breakdown per source url/website. (In order to track the performance of each ad on each sites where the ad has been served and then optimized my campaign).


Would you have any recommendation?
Do you know if there is an Adserver which is able to track the source url where my ad is being served (via variable, or Iframe?) and then can provide a report with the impression breakdown per url?


Thanks for your suggestions!

i cannot help much
but i think for such a large network start your own adcompany will benefit you more
you will be able to generate more money and you need to hire only one person or two

I use Openx , they have 3 versions : business version which they host/maintain and has all features, a free version which they host but has limited capabilities and limited impressions, and a free downloadable unlimited version but you need to host it yourself and you dont get support etc.

I use the self hosted one and it does all what you need, you either need a low end dedicated server or you can run it on a bigger 'shared' server.

good luck
