Displaying Google Searches & Ads from a Different Geography or Region

Now that Google is moving away from a “monolithic” index, it’s common for people in different geographies to get completely different results from a Google search. So when discussing search results with a client or testing geo-targeted adwords, it’s often useful to have Google show me the results as if I were in a different area.

To accomplish this only requires a little manipulation of the query string parameters.

For example, a normal query for mangos might look like this:
https://www.google.com/search?q=mangos

Note that the “q=” query string parameter tells us what the search term is. With the region parameters for San Diego, California added on the end, it looks like this:
https://www.google.com/search?q=mangos&gl=US&gm=825&gr=US-CA&gcs=San%20Diego

The parameters are:

gl = Country code (full list here)
gll = Lat & Long
gr = Worldwide region code (full list here)
gcs = City (but gr must be set to the same value. Full list here)
gpc = Zip code (only works if country code is “US”)
gm = Metropolitan areas of US (full list here)

A handy trick is to let Google set them for you via their Adwords preview wizard . Simply go to:
www.google.com/adpreview

Specify the region and hit search. Then click on the frame properties on the bottom frame and copy the GL,GM,GR, & GCS params out of the URL and paste onto the end of your search.
