For decades, media monetized by way of display advertising, native advertising, branded media, affiliate marketing, and eventually direct commerce. Like a technological progression, the funnel widened and shortened over the years. The definition of media broadened with time. Today, click through rate (CTR) means less to a publisher than the revenue that one visitor accounts for. Accounting for revenue per customer means that customer acquisition cost (CAC) is as much a media metric as it is a commerce one. A publisher now assesses her readership with a measure of lifetime value (LTV); this is especially the case for subscription-based operations. A “like” or other forms of engagement used to matter. Today, the measurement of conversion rate and transaction value are prioritized. Media is a competition for audience ownership; it’s a 360 degree battle for your attention.
