In order for your listing to display a map directly on your page, you need to provide the longitude and latitude of your business’s address. To do this, go to google maps at:
http://maps.google.com/
Type in your address in the map search. Your business address should appear in google maps. It’s centered by default.
When the address you want to find latitude and longitude for is dead center, copy and paste this code into your browser bar:
javascript:void(prompt(”,gApplication.getMap().getCenter()));
A box with the longitude and latitude appears. Copy the first number and paste it into the latitude text box. Copy the second number and paste it into the longitude text box.
That’s it.
