I would like to get feedback from webmasters who have used Google Ad Manager and OpenX, would like to know which one they prefer and why?

I am especially interested in knowing which one has a better capability to rotate ads by percentage of impressions, by ad network and by customers?

Also, would like to know which one has a better Access Control features.

Many thanks for your input.

Admin - Not sure if this is the right category to post this thread, please move this to the correct category it this one is not.

Admanager for a simple reason that it has Geo targeting

I actually test drove both today and found that Openx has lot more flexibility when configuring campaigns for customers.

So for me its definately OpenX.

Hi from OpenX,

Just wanted to jump in and share some news. OpenX is close to a public beta of our hosted ad server called OpenX Hosted. We're adding as many publishers as we can at the moment.

This means all the flexibility of OpenX without the need to maintain an ad server.

cheers,

PS. Both ad servers provide geotargeting... such a useful feature!
