First kudos. Harlan is exactly what I have been looking for. Quick question on rotation and weights though.
I have 5 ads setup. These have all been added to a campaign, with each add set to a weight of 1.
If I visit the page with the ad, I usually get ad1. If I refresh, I usually get ad2, etc. That makes sense if its getting the ad based off IP (trying not to show the same ad twice).
However, looking at the reports, the first ad that was added to the campaign seems to be, by far, receiving the most impressions. Then the second ad, and on down the line until ad 5 where it gets the least.
I assumed it would pull these randomly if the weight was set to be all the same. I suppose I could play with the weighting for ads in the bottom of the list, but that seems to hackish.
Below is a quickie I just did after resetting everything. I have other, similar numbers for a larger sample with similar results.
Ad 1 - 13
Ad 2 - 11
Ad 3 - 8
Ad 4 - 6
Ad 5 - 5
