What is Schema.org?

http://www.seo.com/ Preston Van Dyke (@prestonvandyke) answers the question “What is Schema.org?” in the latest installment in our Commonly Asked Search Marketing Questions series.

Schema.org is a protocol sponsored by Google, Bing, and Yahoo that allows web pages to be tagged and micro-formatted to reflect an entity, rather than existing as a simple online document. For example, a restaurant can use the schema to represent themselves as a restaurant, mark their address & phone number, label reviews, etc., so that search engines can access and label that information more easily.
