We currently run three separate banner ads on our website.
One of my advertisers has complained that they are not getting equal time on the rotation. I have tested this theory on 3 separate computers using different browsers (IE, Mozilla, Google Chrome) and I believe the rotations have been quite fair. However I just tested on a fourth computer and the same ad keeps refreshing!
I am noticing that the rotation is sometimes random, other times it seems spot on. Has anyone else had issues with this? If so, any advice on how to explain this to the advertiser? Is there a report I can share that shows # of views? One of the other advertisers has three different ads rotating, but I set it up so that they would only get 1/3 of the rotation for the three ads. Any tips on how to make things more fair?
