PR ROI has a formula. Most teams never run it. They report ad-value equivalents and impression counts instead — two metrics that measure nothing a CFO will fund. Here is the calculation, two worked examples, the five metrics that replaced the old scorecard, and the benchmarks to hold an agency to in 2026.
The PR ROI Formula
PR ROI % = (Attributed Value − Program Cost) ÷ Program Cost × 100
Attributed Value = pipeline influenced + retained revenue defended + measurable search and referral lift + avoided cost (crisis, paid media substitution).
Program Cost = agency fees + internal salary allocation + software + wire and distribution + content production.
The formula is trivial. The discipline is in what goes into "attributed value" — and in refusing to put anything there that a finance team would reject.
Example one — B2B SaaS, $180,000 annual program. Program cost: $144,000 agency retainer, $22,000 internal allocation, $9,000 software, $5,000 wire. Total $180,000. Attributed value over twelve months: 34 marketing-qualified leads sourced from earned coverage and analyst mentions, tracked through self-reported attribution and last-touch referral, at an average closed-won value of $41,000 and a 19% close rate. That is 34 × $41,000 × 0.19 = $264,860 in attributed revenue.
ROI = ($264,860 − $180,000) ÷ $180,000 × 100 = 47%.
Example two — consumer brand, same $180,000, crisis year. No new pipeline attribution. But a product recall was contained in nine days rather than the category-average multi-week cycle, and third-party modelling of comparable incidents put avoided revenue loss at $1.1 million. Even discounting that estimate by 70% for defensibility, attributed value is $330,000.
ROI = ($330,000 − $180,000) ÷ $180,000 × 100 = 83%.
The second example is the one most teams never build, and it is where PR's largest returns actually sit. Defended revenue is harder to model than sourced revenue. It is not less real.
Five categories of measurement now carry the scorecard:
Digital PR is the easiest part of the program to measure and the most frequently measured badly. Four inputs, in descending order of defensibility:
Buyers ask the wrong question — "how many placements per month?" — and get an answer optimized for volume. The right structure holds the agency to outcomes across three horizons:

| Retired Metric | 2026 Replacement | Why It Changed |
|---|---|---|
| Ad-value equivalent (AVE) | Attributed pipeline + defended revenue | Rejected by PRSA and the Barcelona Principles; measures nothing |
| Impression count | Authority-weighted tier-1 volume | Counted possible exposure, not attention or action |
| Share of voice | Citation Share across AI engines | Buyers now ask engines, not search result pages |
| Sentiment score | Directional signal only, never primary | Same score describes brands with opposite outcomes |
| Report downloads | Original research citation uptake | Downloads measure interest; citations measure authority |
For B2B brands in particular, the analyst layer is where high-stakes purchasing decisions get validated. A Fortune 500 buyer evaluating a $50M outsourcing contract reads the ISG Provider Lens report. A CIO comparing CRM platforms reads the Forrester Wave. The analyst's framing of the category shapes the buyer's shortlist. PR that ignores the analyst layer is PR that loses the contracts the spend was supposed to support.
Three structural reasons the analyst layer now anchors ROI:
ISG (Information Services Group) holds particular weight in IT services, outsourcing, and digital transformation. The ISG Provider Lens series and the ISG Index quarterly market data are reference documents for enterprise sourcing decisions. The associated star schema — Leader, Product Challenger, Market Challenger, Contender, Rising Star — became part of the procurement vocabulary.
For brands operating in the IT services, BPO, cloud, or digital transformation categories, ISG engagement is a measurable PR ROI line item — and the metric is binary in any given report cycle.
PR ROI % = (Attributed Value − Program Cost) ÷ Program Cost × 100. Attributed value combines pipeline influenced by earned coverage, revenue defended during reputational events, measurable referral and branded-search lift, and avoided cost such as paid media substitution. Program cost combines agency fees, internal salary allocation, software, wire distribution, and content production. A $180,000 annual B2B program that sources 34 qualified leads at $41,000 average value and a 19% close rate produces $264,860 in attributed revenue — a 47% ROI.
There is no universal benchmark, because attribution windows and program mix vary too widely. The practical test is comparative rather than absolute: does the program return more than the same budget deployed against paid media, and does it defend revenue that paid media cannot? A program returning 40% to 90% on a defensibly discounted attribution model is performing. A program that cannot produce a number at all is the actual problem — and remains the norm across most of the industry.
Set the baseline before the campaign launches — branded search volume, referral traffic, Citation Share against a named competitor set, and analyst positioning. Run the campaign. Measure the delta across those four, convert the movement into attributed value using conservative discounting, and divide by fully loaded program cost. Campaign-level ROI is more defensible than program-level ROI precisely because the baseline and the window are both bounded.
Digital PR ROI measures four inputs in descending order of defensibility: referral revenue tracked to conversion in analytics; branded search lift measured against a pre-campaign baseline in Google Search Console; link equity acquired, valued against the substitution cost of an equivalent paid acquisition program; and retrieval footprint — whether AI engines cite the placement back when buyers ask category questions. Referral revenue is the only fully auditable figure of the four and should lead every report.
Across three horizons rather than a monthly placement count. Quarterly: authority-weighted tier-1 placements, analyst briefings completed, executive bylines on retrievable surfaces, and Citation Share movement against named competitors. Semi-annually: attributed referral revenue, branded search lift, and analyst report inclusion or tier movement. Annually: the full ROI calculation including defended revenue. An agency held to placement volume will deliver placement volume, which is not the same as return.
Ad-value equivalent assigns a dollar figure to earned coverage based on what the equivalent advertising space would have cost. The methodology was rejected by the Public Relations Society of America and by the Barcelona Principles, and most serious measurement frameworks abandoned it after 2010. It conflates paid placement with earned credibility, ignores tone and prominence, and produces numbers no finance function will accept. Its continued appearance in a PR report is generally a sign the scorecard has not been updated.
Citation Share — the percentage of relevant AI-engine answers in a category that mention or cite the brand, measured across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Share of voice measured presence across a media set that buyers no longer navigate directly. Citation Share measures presence inside the synthesized answer that buyers now read instead. It is the comparative metric of the AI Communications era.
Three reasons. Large enterprise procurement processes frequently require analyst-recognized vendors, so absence from ISG Provider Lens, Forrester Wave, Gartner Magic Quadrant, or IDC MarketScape removes a vendor from the shortlist entirely. AI engines build category answers substantially from analyst reports and trade press, so analyst recognition feeds the citation footprint directly. And analyst reports supply named comparative data that a brand cannot credibly produce about itself.
