Tracking External Banner ads

in google analytics

[Skylo]

Hi,

I have approximately 5 banner ads running on almost a hundred other sites. Does anyone know how i can track these banner campaigns in Google analytics? I currently use HPX and you are able to do this, however I am not happy with their solution as a whole and will migrate to GA if its possible for me to track these banner campaigns.

Your insight would much appreciated.

I would be interested too, especially if there was a way to measure clicks as well as impressions.
