An Apostate View on ROI in PR
Executive takeaway:
PR creates measurable value but traditional ROI is the wrong primary lens. Treating earned media like performance media is a category error that obscures impact rather than clarifying it.
First-year philosophy students learn about category errors: applying a concept where it simply doesn’t belong. Numbers don’t have colors.
Much of how we measure PR suffers from the same flaw.
Earned media is not a discrete sales lever. Its impact accrues through reputation, trust, and market position over time. It behaves like a long-horizon, systemic signal not a short-cycle conversion driver. Forcing it into paid-media ROI constructs (impressions, CTR, last-touch conversion) answers the wrong question with increasing analytical confidence.
Why Traditional ROI Breaks for PR
Long-cycle, multi-touch influence
Earned coverage shapes credibility, awareness, and brand framing across months and many stakeholder touchpoints. Most ROI models assume short-term causality between exposure and transaction.
Attribution blindness
Marketing analytics observe only fragments of the journey. Silent but necessary influences, like a credible feature story, often receive zero credit even when they enable downstream paid or direct response success.
Flawed monetary proxies
AVE and EMV rely on arbitrary multipliers and ad-rate analogies. They overstate precision while ignoring what actually drives impact: prominence, sentiment, message pull-through, and credibility.
What Measurement Should Focus On
I recently reported 4B earned impressions for a global client. With a global population of ~8.3B, impressions quickly become a vanity metric; useful for storytelling, weak for decision-making.
If impressions are the headline metric, we should ask what they actually explain.
A modern PR measurement framework should focus on reputational capital, expert visibility, and positive brand familiarity at key inflection moments, using both quantitative and qualitative signals:
Illustrative metrics
- Brand prominence and context within coverage
- Inclusion in agenda-setting, top-tier media
- Key message pull-through
- Composite media quality scores
Reputation impact
- Lift in reputation drivers (exposed vs. unexposed)
- Share of voice by priority topic, market, and sentiment
- Themes and frames owned versus competitors
Emerging signals
- Brand presence and prominence in LLM-generated results
- Accuracy of LLM interpretation of core brand messages
A Necessary Clarification
This is not an argument that PR should escape accountability or financial scrutiny. It is an argument that last-touch ROI is structurally unreliable as a primary measure of earned media value. In some cases, downstream impact can be modeled but treating that as the norm misrepresents how PR actually works.
Earned media remains a critical component of modern marketing engines. But measurement only creates insight when the question fits the nature of the signal.
ROI is a powerful tool. It’s simply the wrong one to lead with for PR.
