We all know that optimizing adsense revenue take time and effort. Not all of us are good at everything, so have you ever consider working with an agency to help you improving your income? Especially those have qualified Google Certified Publishing Partner

I run OKO, the newest GCPP (we were previously AdSense Partners before that programme was retired). We work with publishers around the globe and I think that almost every other GCPP does too.

I'm not sure of the thinking behind having the geo-selection on the partner pages. It doesn't seem to reflect on the remote nature of the work or the global coverage of the companies delivering it. My advice would be to talk to the companies who's approach and services best suit you and don't worry too much about the physical location unless you feel face to face contact is a requirement.
