Advertising value equivalency versus modern measurement
Launch library · evergreen read
Advertising value equivalency estimates what earned coverage would have cost if it had instead been purchased as advertising space, translating column inches or airtime directly into a single dollar figure for reporting purposes. It was once a common shorthand for demonstrating value, largely because it produced one easily reported number that stakeholders found genuinely intuitive to understand at a glance.
Its central flaw is treating earned and paid media as roughly equivalent in value, when in reality they are not comparable at all. Earned coverage carries a form of credibility that advertising simply cannot buy at any price, and its true worth has little to do with what the same physical space would have cost as a purchased advertisement instead.
Modern measurement approaches instead try to assess whether coverage actually shifted awareness, perception or behaviour among a real audience, which is considerably harder to calculate but far more honest about what communication is genuinely meant to achieve for an organisation. Many professional bodies now actively discourage advertising value equivalency for exactly this reason.
