I found a great tool called OpenX, it’s an open source ad server where you can manage your advertising spot, rotate banners, geo-target ads, track performance, log statistics and so much more.
I have been playing with the settings and experimenting on different combinations of ads that would yield the highest earnings for my website. I was amazed by the significant performance gains on my advertising spot specially when i used geo-targeting.
I also set priorities for ad displays of my advertisers giving higher priorities to those with better CPM rates. My main site has a lot of southeast-asian visitors and many advertisers have stopped serving/paying ads for such traffic. Thus i geo-target ads for SEA visitors to optimize earnings.
The only down-side of implementing openX on my site was the significant increase in the server load, specially when i enabled the GeoIP targeting and the statistics logging. For high traffic sites it is advised to host the openX adserver in another dedicated server or at least a VPS. Running it from a shared hosting will only get you booted out in a few days for overloading the shared server.
