One of the challenges that Google DFP (Ad manager) account managers especially those who are new often face is to set up different Ad banners for different regions or countries and to test them out. The challenge is not to set up different Ad banners since that can be easily done by creating different line items and selecting target criteria and setting Geography. Challenge is to verify whether correct banners appear in targeted region or country?
One can easily verify the Ad banners for the country or region he or she is browsing in but to verify Ad banners in other countries either you need a remote server in all those regions or countries or use some good proxy. You may also seek help of your friends if you are lucky enough to have friends in all those countries.
If you don’t have access to all the things mentioned above, try this simple technique and you would be able to see Ad banners from most parts of the world. Visit some performance testing website which has option to select country and which also provides screen shots in result set.
Two such websites are http://www.webpagetest.org/ and http://loads.in/. By using these websites you would be able to verify which Ad banners appear in different countries. Using this technique you can test any public web page and make sure that Ad is rendering fine without any hiccups.
