Your Google profile displays photos, links to your blog or other online profiles, and ways for people to contact you. Now you can display your public location badge on your Google profile. To add your location, you first need to enable the Google public location badge. Once you've enabled the Latitude badge, go to the Edit profile page and check the box next to 'Display my Latitude location.' Your Google profile will now display your most recent location if it was updated in the last 24 hours. Note that only your location, not the badge itself, will appear on your profile.
