This web site provides a free online tool that automatically generates HTML <meta> tags containing geo (lat/lon) data:
It has a form that you simply fill in with your data and out pops the <meta> tags. For example, I filled in the data for Boston and here are the <meta> tags that were automatically generated:
<meta name=”DC.title” content=”Boston” />
<meta name=”geo.region” content=”US-MA” />
<meta name=”geo.placename” content=”Boston” />
<meta name=”geo.position” content=”37.09024;-95.712891″ />
<meta name=”ICBM” content=”37.09024, -95.712891″ />
Here’s a section of the web page which describes the value of embedding geo metadata into your web pages:
What are Geo-Tags for?
According to a survey of The Kelsey Group (Princeton, NJ, USA) from the year 2004, 25% of all commercial online searches are local searches. It understandably makes little sense to look for a baker and find one who has his shop in a completely different town. Today search engines are already able to handle regional search requests, gathering city and street names from the text content of the explored web pages. Geo tags will simplify this task since they provide machine-readable information about country, region and exact latitude/longitude coordinates.
