I'm wondering how I can get around localized search results in Google for national keywords. I work on several sites that target geo specific keywords in different cities (i.e. "widgets in chicago"), as well as, national search terms (i.e. "widgets"). When I do a search for our national keywords (i.e. "widgets"), I get localized search results even when I'm not logged in. I know that Google is showing results based on my IP location. This is very annoying.
Is there a way to change my IP location to different cities so that I can see results in those areas? An IP proxy maybe?
