While I am close to being sold out selling banner inventory to my US visitors, my non-US traffic remains unmonetized. All of the big advertisers simply insist on geotargeting US and on the rare occasion, the UK. I can't even get anyone to look at my Canadian or Australian traffic, nevermind Eastern Europe or India, which is a huge chunk of our visitors. Are there any agencies out there who can help fill this niche? Any other ideas?
