Google’s John Mueller said in a video hangout a day or so ago that Google doesn’t use the GeoCoordinates, GPS coordinates in your schema or structured data for search purposes.
At the 38:20 mark into the video John said “we don’t use GPS coordinates in that regard.”
The question was:
A quick question about GPS coordinates in schema. Is it essential using GPS coordinates within code or via schema for a website business focusing for its clients based in different locations or states in a country?
As far as I know, we don’t use GPS coordinates in that regard.
So if you have addresses on a page then that’s something I would mark up but as far as I know we don’t use GPS coordinates. So this here if your business is located in place where there is no actual postal address, I don’t know what we would do in a case like that.
If that’s the situation for you then I would love to find out more. So feel free to maybe contact me on Twitter or on Google+ and I’ll try to figure out a little bit more with the schema.org folks on our side. If it’s really a matter of different business locations and you do have addresses then I would focus on addresses and not GPS coordinates.
