Earned media value: how to calculate EMV and what it is worth

Earned media value (EMV) is what earned coverage would have cost you as paid advertising. You calculate it by dividing impressions by 1,000 and multiplying by a cost per thousand impressions (CPM). Earned media is exposure you don't pay for, such as press articles, reviews, podcast spots, and creator posts.

Earned media now shapes a second channel: AI answers. Earned offsite coverage is content about your brand on sites you don't own. AI answers draw heavily on those third-party sources, as the research below shows. AirOps tracks brand mentions and citations across ChatGPT, Gemini, and Perplexity, and this guide applies that lens to earned media.

A citation is when an AI answer links or footnotes a page as a source. A mention is when an AI answer names a brand, with or without a link. Share of voice is your brand's share of all brand mentions across a tracked set of prompts.

This guide gives you the formula and a worked example first. Then it shows what to report when leadership asks what earned media is worth.

What is earned media value?

Earned media value is a dollar estimate of what your earned exposure would have cost to buy as advertising. In marketing, EMV is the shorthand for that estimate across public relations (PR), social, and influencer coverage.

EMV is an estimate of ad cost, so it never shows up in revenue. The result moves with every CPM you choose.

EMV survives because it answers leadership's question in a unit leadership already uses. A dollar figure is easy to set beside ad spend.

What is earned media and what are some examples?

Earned media is coverage you didn't pay for and don't control. Examples include:

• News articles and trade press coverage
• Product reviews on third-party review sites
• Listicles and comparison roundups on other companies' blogs
• Podcast interviews and guest spots
• Creator and influencer posts you didn't sponsor
• Community threads, such as Reddit discussions

Earned media is broader than PR. PR is one way to earn coverage, through pitching and press relationships. Reviews and community threads count as earned media too, even with no PR work behind them.

Muck Rack's May 2026 study, covered below, classed 0.3% of AI-cited links as paid or advertorial.

EMV says nothing about that last column. Earned coverage is one input into authority for AI search, alongside the pages you own.

How do you calculate earned media value?

You calculate earned media value by dividing impressions by 1,000 and multiplying by a CPM. The core formula is EMV = (impressions ÷ 1,000) × CPM. Here is how to calculate earned media value with that formula.

How to calculate EMV step by step

1. Collect the earned placements for one period, such as a quarter.
2. Record impressions or reach for each placement from the outlet or your monitoring tool.
3. Pick one CPM per channel from your own paid campaigns, and write it down.
4. Divide each placement's impressions by 1,000 and multiply by that CPM.
5. Add the results, and list every input and multiplier next to the total.

Three common earned media value formulas

Vendors add assumptions to the core formula in different ways.

Launchmetrics publishes the engagement-adjusted version in its earned media value guide, updated September 2026. The same guide says there is "neither a standardized approach nor definitive criteria" for calculating EMV. Launchmetrics sells its own replacement metric, so read that critique with its incentive in mind.

Muck Rack's help documentation (undated, accessed October 2026) describes a default advertising value equivalency (AVE) formula.

It multiplies a site's monthly unique visitors from SimilarWeb by 0.025 and by $0.37. Muck Rack calls this the "industry standard formula," but that label is its own. Both multipliers are adjustable assumptions.

An earned media value calculator example

This hypothetical example shows how to calculate earned media value in any EMV calculator. A trade article earns 200,000 impressions. Your paid social CPM is a hypothetical $10.

200,000 ÷ 1,000 × $10 = $2,000 estimated media cost equivalent.

For your own report, replace $10 with [your CPM] from your ad account. No authoritative public CPM table exists, and your own paid data is the input you can defend.

The most common error is skipping the division by 1,000. Multiplying 200,000 by $10 gives $2,000,000, a thousandfold overstatement. Check every earned media value calculator you use for this step before you trust its output.

The traffic-based default shows how much assumptions drive the result. A hypothetical outlet with 10 million monthly visitors gives 10,000,000 × 0.025 × $0.37 = $92,500 per article. Change either multiplier and the total changes with it.

Common EMV calculation mistakes

• Switching CPMs between reports, so quarters can't be compared.
• Counting a roundup that names five brands as full exposure for your brand alone.
• Hiding multipliers or adjustment factors from the people reading the report.
• Calling the total "value" or return on investment (ROI), which the main standard tells you to avoid.

Is earned media value a reliable way to measure PR?

No. The main standards bodies for communications measurement reject EMV as a measure of value. At most, they accept it as a disclosed estimate of the cost of space.

The International Association for Measurement and Evaluation of Communication (AMEC) published the Barcelona Principles V4.0 in June 2025. Principle 5 states that "invalid measures such as advertising value equivalents (AVEs) should not be used." AMEC asks you to measure outcomes and impact instead.

AMEC names EMV among the AVE variants it calls "essentially variations of the same flawed metric." If you still report one, AMEC says to avoid the words "value," "impact," or "ROI." You should also disclose the metric's limitations and every multiplier you used.

By that rule, the name earned media value breaks AMEC's own guidance. Label your figure "estimated media cost equivalent" instead. The math stays the same.

The position is more than a decade old. The Institute for Public Relations (IPR) Commission on Measurement and Evaluation voted unanimously against AVE on October 8, 2010. The commissioners found "no evidence to suggest that advertising and editorial space hold equivalent value."

Media impact value and related PR metrics

Media impact value (MIV) is Launchmetrics' answer to those critiques. Launchmetrics describes MIV as "a proprietary algorithm" built for the fashion, lifestyle, and beauty industries. It is one vendor's metric for one sector, so it doesn't transfer cleanly to business software.

Here is how EMV compares with related metrics.

Impression counts treat every reader as equal. A trade publication your buyers read gets the same CPM as a scraped content farm.

"…lots of impressions off of AI is not a good metric," says Eli Schwartz, author of Product-Led SEO, in an AirOps webinar. The same logic applies to EMV. The formula prices reach, and it has no input for placement quality or buyer fit.

PR professionals feel the gap. Muck Rack's 2024 measurement survey polled 397 respondents in October 2024. Muck Rack recruited them mainly from its own contacts, with a margin of error near 5 points.

In that survey, 49% were somewhat confident in the metrics they report. Fewer than 4 in 10 were very or extremely confident. About three-quarters still use reach or impressions.

How do you measure earned media in AI search?

You measure earned media in AI search with three separate measures on a fixed set of category prompts. Mention rate is the share of answers that name your brand. Citation rate is the share of answers that cite one of your pages as a source.

Share of voice compares your mentions with every brand mentioned across the same prompts. Keep the three apart in reports, because each answers a different question.

Earned media measurement in AI search starts with that split. Treat mentions and citations as separate goals. Coverage on third-party sites is how you get named, and your own pages are what AI can cite. Impression counts capture neither.

Mentions are "truly the gold metric of AI search," says Chris Long, co-founder of Nectiv, in an AirOps webinar. A citation sends credit to a page, while a mention puts your brand name in front of the buyer. Track both, and read the mention rate first.

What the research says about AI sources

Two vendor studies describe where AI answers draw from. Muck Rack's What Is AI Reading? report (May 2026) analyzed 25 million+ links from ChatGPT, Claude, and Gemini. About 84% of cited links came from sources Muck Rack classes as earned.

That bucket is broad. It includes Wikipedia, government sites, social posts, and third-party corporate blogs. Journalism made up about 27% of citations, and paid or advertorial content made up 0.3%.

Muck Rack sells generative engine optimization software. Its study counts links, which makes it a citation measure only.

AirOps' own research looked at mentions instead. In the AirOps offsite signals report (October 2025), 85% of 21,311 brand mentions came from third-party domains. The sample covered 500+ discovery queries across ChatGPT, Claude, and Perplexity.

Neither study proves that earned coverage causes AI visibility. Both describe answers that lean on sources you don't own, which is where earned media lives.

How to set up AI search tracking for earned media

1. Use category prompts your buyers ask, and leave out prompts that name your brand.
2. Spread prompts across the funnel: problem questions, solution questions, and vendor comparisons.
3. Measure your top competitor's mention rate and set it as your target.
4. Log each new placement with its publish date so you can compare before and after.
5. Give placements months before you judge movement at the topic level.

How do you report earned media ROI to leadership?

Report earned media ROI as a scorecard. Lead with AI visibility rates and self-reported attribution, then connect both to pipeline. Include EMV only as a labelled estimate of the cost of space.

Click-based reports miss exposure that happens inside the answer. Pew Research Center tracked 900 U.S. adults' Google searches in March 2025 and published the results in July 2025. People clicked a traditional result in 8% of visits with an AI summary, against 15% without one.

Pew reports an association, and it covers Google only. Still, the gap changes how you read Google Analytics 4 (GA4), which counts visits after a click.

Paid search budgets come with targets, attribution, and a weekly review. "AI search has earned that same treatment," says Josh Grant, former VP of Growth at Webflow, in an AirOps webinar.

Give your earned media program the same cadence, with a named owner and a fixed review day. A weekly look at mention rate shows a drop long before the quarterly report.

Attribution is the hard part. AI answers build awareness inside the answer itself, and click-based tools only see what happens after a click.

"…AI is not a referral play, it's a visibility play, but most of our attribution is click-based attribution," says Kevin Indig, growth advisor and author of the Growth Memo, in an AirOps webinar.

That mismatch is why a visibility metric belongs at the top of your scorecard. In the clip below, Kevin Indig explains which brands gain and lose visibility in AI search, and why.

Self-reported attribution fills the gap clicks leave. Alex Halliday, co-founder and CEO of AirOps, suggests splitting topics into two groups and doing offsite work on one. You then compare inbound lift between them and ask buyers where they heard about you.

Sydney Sloan, former CMO of G2, advises marketing leaders to keep the data high level and show trends. Give your chief financial officer (CFO) a steady trend line and a clear method.

What to do next with earned media value

Keep the formula you have, and add the measures that show outcomes.

1. Pick one EMV formula and one CPM per channel, and keep both fixed for a year.
2. Rename the output "estimated media cost equivalent" and publish your method beside it.
3. Build a set of category prompts and record your baseline mention rate, citation rate, and share of voice.
4. Set your top competitor's mention rate as your target.
5. Add a "How did you hear about us?" field to sign-up and demo forms, with AI assistants as an option.
6. Report trends to leadership every quarter, and tie each trend to pipeline.
