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

Dr. Joanne Levin-O'Brien developed the 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 36 million in less than two years, and the 240,000 plus videos (up from 21,000 in the last two years) to choose from in Blinkx.
