Not with advertising value equivalency, which is the metric most PR reports still lead with. AMEC, the industry body that sets measurement standards for public relations, rejected AVE outright in its original Barcelona Declaration of Measurement Principles in 2010, and it has restated that rejection through every update since, including the Barcelona Principles 4.0 released in 2025. Fifteen years after the industry itself said to stop, a lot of agencies still hand clients a number built on it.
What is AVE, and why did the industry reject it over a decade ago?
Advertising value equivalency takes the column inches or airtime a piece of coverage occupies and prices it as if that space had been bought as an ad, often multiplied by three or five to account for earned coverage supposedly being worth more than paid. AMEC's own text is specific about why that fails. Principle 5 of the Barcelona Declaration states plainly: "AVEs do not measure the value of public relations and do not inform future activity; they measure the cost of media space and are rejected as a concept to value public relations." The same principle goes further on the multiplier habit: "Multipliers intended to reflect a greater media cost for earned versus paid media should never be applied unless proven to exist."
Both problems are real. Pricing a journalist's independent article at an advertising rate treats a reporter's judgment as if it were a media buy, which erases the exact thing that makes earned coverage different from an ad: nobody reads it as paid. And the multiplier that is supposed to correct for that difference is, in AMEC's own words, invented rather than measured. A number built on an invented multiplier is not more credible for having more decimal places.

If not AVE, what should you actually count?
AMEC's standard points communications work toward three tiers, and the distinction between them is the part most reports skip. Outputs are what you produced or placed: the press release that went out, the article that ran, the podcast booking that happened. Outtakes are whether the audience actually noticed, understood or reacted to it: did the right people see the coverage, and did it land the message you intended. Outcomes are whether something the business cares about moved as a result: a change in awareness, consideration, inbound inquiries, hiring applications, or search behavior tied to the coverage window.
Most PR reporting still stops at outputs, which is the easiest tier to count and the least connected to anything a CEO cares about. Muck Rack's State of PR Measurement report, a survey of more than 800 communications professionals, found that reach and impressions, an output-level count of how many people theoretically could have seen a piece of coverage, remained the second most commonly reported metric, used by 79% of respondents. That is the industry's own practitioners, more than a decade after Barcelona, still defaulting to the tier of measurement that tells a client the least.
What does share of voice actually measure, and what does it miss?
Share of voice is simpler than AVE and more honest about its own limits: it is your brand's mentions as a percentage of total mentions across a defined set of coverage, usually against a named list of competitors over a fixed period. It is useful for one specific question: are you gaining or losing ground against the companies you compete with for the same buyers' attention.
It answers that question and almost nothing else. Share of voice does not know whether a mention was favorable, neutral or damaging, so a product recall that gets you written about constantly will spike your share of voice while your actual standing with buyers falls. It also treats a single sentence in a roundup the same as a dedicated feature, unless you build a weighting into it yourself, which most teams do not bother to do. Use it as one input next to a stated PR strategy with clear goals, not as a scoreboard on its own.
How do you tie coverage to something the business actually feels?
A handful of outcome-level checks are available to any company, without a specialized measurement vendor.
- Referral traffic from the specific placement, tracked with a UTM-tagged link whenever a publication will include one, so you can see whether anyone followed the story to your site rather than just reading it in place.
- Branded search volume before and after a placement, since a jump in people searching your company name in the days after a story runs is a reasonable, if imperfect, signal that the coverage reached people who were not already looking for you.
- A "how did you hear about us" field in your sales or signup flow, checked against your coverage calendar for spikes that line up with specific placements.
- Independent citations of your own research, if you publish studies, since the point of a study is that other people repeat your number rather than download your PDF, a distinction covered in our guide to announcing a study or research report.
- Coverage that search engines and AI assistants have actually picked up, which typically takes the days-to-weeks window discussed in our guide to PR timelines rather than showing immediately.
None of these numbers prove causation on their own. A branded search spike the week a feature ran could be coincidence. Several of these signals moving together, in the same window, across more than one placement, is what starts to look like evidence rather than a story you are telling yourself.
What does AI visibility add to this measurement stack?
A genuinely new outcome to watch, and one most PR reporting does not include yet. Muck Rack's May 2026 study of more than 25 million AI-cited links found that earned media accounts for 84% of what ChatGPT, Claude and Gemini cite, against 0.3% for paid and advertorial content. That means the same earned coverage you are already reporting on, by outputs, outtakes or outcomes, is also the raw material AI assistants draw on when someone asks them about your category.
Two measurement tools make that trackable now. Google's own Generative AI performance report inside Search Console, live worldwide since August 2026, shows how often your pages appear inside Google's AI Overviews and AI Mode. And the paid cross-platform tools covered in our rundown of the AI visibility market track citation and mention patterns across ChatGPT, Gemini and Perplexity directly. Checking either on a quarterly cadence, alongside your existing coverage reporting, turns "AI visibility" from a vague aspiration into a line item with a number attached, the same way outcome-level PR measurement should have treated earned coverage all along.
The direct answer, for anyone who read this far
Stop reporting advertising value equivalency. AMEC's own measurement standard rejected it in 2010 and has restated that rejection through the 2025 Barcelona Principles 4.0 update, on the grounds that it prices media space, not public relations, and leans on multipliers nobody has proven. Measure outputs, outtakes and outcomes instead, with outcomes, referral traffic, branded search lift, sales-flow attribution and now AI citation tracking, carrying the most weight because they are the tier closest to something the business actually feels. Share of voice is a useful competitive check, not a verdict on quality.
