We developed a classification system or Content Map to make exploring sustainability by our audience efficient, educational, and inspirational.

Dr. Joanne Levin-O'Brien developed the Sustainability Content Map after researching both print and online content. It is specific to the subject of sustainability and unique to EarthSayers.tv.

We use the Content Map to assign relevant keywords. Each Keyword or phrase is linked to a category and each category rolls up into one of four segments: overview, planet, humanity, and prosperity.

Our audience may explore sustainability by segment, category, or keywords.

We have gone beyond search and the 15 million plus references to the term in Google, now up to nearly 95 million in less than three years, and the 347,000 plus videos (up from 21,000 in the last three years) to choose from in Blinkx. (August, 2011)
