Hi All My question for today can you explain the concept - "the long tail of search." My views: The long tail is an economic theory of demand. It posits that in the modern American economy, there are popular products and unpopular products in every sector and segment of demand and that, in any of those given sectors, a demand curve exists with a few popular products that have high demand and a great number of unpopular products that have a much smaller amount of demand per product. Long tail theory says that in any given demand curve, the "tail" or unpopular products, when combined, will have a greater amount of demand than the popular products at the "head.' Please give valuable comment... Thanks in advance
