I am from Canada and the adwords I see are alot different from what a U.S. person sees. How can I browse the net so that Yahoo, Google, and MSN show U.S.A. based ads instead of Canadian ads? As they see my Canadian IP and show CDN ads only. Yes, I know I can go to here www.google.com/adpreview but that works for google only. Is there a good site that allows you to search via proxy to see what the ads look like? It is very frusterating not being able to see what the main audience sees.
