freshness factor

An online business measurement that takes the average content refresh rate (how many times your Web site is updated) and divides it by the average visit frequency rate (how often people come to your site). A freshness factor of less than 1 means that users are seeing stale content, since they visit more often than you change your content. A freshness factor greater than 1.5 means your content changes more often than users come to see it, and that equals wasted resources.
