Policing Geotargeted ad display has become a crucial function for many advertisers marketing and media departments.  The questions of whether or not an advertisers well crafted and expensive digital campaign is reaching the impression goal seems to be secondary anymore.  The questions now seem to be all about whether or not that well crafted and expensive campaign is even reaching the desired DMA. 
Many advertisers have a tendancy to assume that their US only based campaign is staying in the US.  Advantage Media, Inc. has seen an increasingly and alarming new trend of AdNetworks serving US based (only) impressions to international visitors.  More importantly advertisers, agencies and adnetworks don't even know it's happening.  
With the help of Double Verify (www.doubleverify.com) Advantage Media, Inc. has been able to help and solve this very problem.  It is Advantage Media Inc.'s opinion that if Advertisers don't push their ad agencies to monitor and track their US only impressions then ultimately it is the Advertiser, not the agency that will pay the piper.
