Google Location URL Arguments That Don’t Work!
There are many places that list out the arguments below and say that you can change the target geographical search location on Google by appending them to the search URL. However, with the new Google Location Personalization, these arguments are no longer valid. Here’s a list of the arguments relating to search location that no longer work.
This references a country. This argument actually still works on other countries’ search pages. If you go to Google’s UK site, and put gl=US in the url, it will actually give you the US search results.
This references longitude and latitude.
This references a state. Regions in other countries use a similar format.
This references a city.
This references a zip code.
This references a geographic location code that they published.
