Earned Media Value (EMV)

Earned Media Value (EMV) is an estimate of what the organic reach generated by unpaid mentions, shares, and press coverage would have cost if the same exposure had been bought as advertising.

There is no single standard formula: most methodologies assign a notional cost per impression or engagement to each mention, weight it by the size or influence of the account posting it, and sum the results, though the specific weightings vary between vendors and are rarely published in full. This makes EMV useful for internal trend tracking but weak for comparing figures produced by different tools.

Marketing and PR teams use EMV to argue for the value of influencer marketing and social listening-driven campaigns that generated no direct ad spend, translating share of voice into a figure executives can compare to paid budgets. The main pitfall is presenting EMV as equivalent to real revenue or even to real media spend: it is a notional, often inflated proxy, and because methodologies differ, the same campaign can produce very different EMV numbers depending on which tool calculated it.
