5-15 percent: That’s the percentage of many news sites monthly unique visitors that drive half or more of their pageviews. That’s a jaw-dropping number, and one that news companies are just beginning to acknowledge — privately. Why be quiet about it? Look at the annual reports and quarterly financial disclosures of the public companies; they trumpet uniques and pageviews. Yet in the age of news ubiquity, we’ve reached near-infinity in pageviews and of ad inventory. Is there much meaning left to one random web visitor hitting one random web page, courtesy of Google or Facebook, some time in any given month? Not much. Yet, that’s what most people still point to publicly. Privately, the question is the 5-15 percent. These are your customers. How much will they pay for access? How much more valuable are they to targeting advertisers, given you know much more about their reading and shopping habits? The metric needed: How much does a core customer yield annually, and in a lifetime? Then: How do I most efficiently find and convert more of them?
