The news today out of Techcrunch is confirming the rumors about a location product/service from Facebook. For site owners perhaps a way to prepare for this can be found in the recent Open Graph documentation that launched with the new “Like” feature. Under “Recommended Meta Data” it includes specifics on embedding location information into your page:
This is useful if your pages is a business profile or about anything else with a real-world location. You can specify location via latitude and longitude, a full address, or both.
Facebook provides an example snippet for this location data as well:
<meta property="og:latitude" content="37.416343"/> <meta property="og:longitude" content="-122.153013"/> <meta property="og:street-address" content="1601 S California Ave"/> <meta property="og:locality" content="Palo Alto"/> <meta property="og:region" content="CA"/> <meta property="og:postal-code" content="94304"/> <meta property="og:country-name" content="USA"/>
For sites that expose real world entities, such as a business’ home page, directories or similar, these tags could be essential for either a Facebook powered location product (like Foursquare) or even just to suggest relevant local pages for a user. Taking a quick look at some sites that have implemented the “Like” feature I have yet to find one that is using these tags but I have not performed an exhaustive search.
