Has anyone come across this problem? I checked from 10 different US based desktops, and I get a full page ad from adbrite on every computer on my site. Yet, the adbrite stats tell me that only around 25% of US traffic is served (Note, I only show full page ads to US surfers, our geo targeting is 99% accurate). A few months back, the rate was around 50% Do you have the same problem? thanks
