Where EMV Fits: The PESO Framework

EMV sits within the PESO framework — the model that categorises all media into four types:

Paid media: Exposure purchased through advertising — Google Ads, Meta Ads, sponsored content, display advertising. You pay per impression, per click, or per acquisition. The reach stops when the spending stops.

Earned media: Exposure generated organically by others — customer content, reviews, word of mouth, press coverage, social shares, and mentions. You do not pay for each impression. The exposure persists and compounds over time.

Shared media: Exposure distributed through social channels — both the business's own social presence and content shared by customers on their personal networks. Overlaps with earned media when customers share brand-related content.

Owned media: Exposure through channels the business controls — its website, email list, blog, and owned audience. The business decides what to publish, when, and to whom.

Earned Media Value quantifies the earned media component — the exposure the business did not pay for but received because customers chose to create and share content about it. In a participation economy model, earned media is not random. It is the systematic output of a participation system that prompts, rewards, and tracks customer contributions.

Three Ways to Calculate EMV

There is no single industry-standard formula for EMV. Three approaches are commonly used, each with different strengths. The most accurate EMV calculations use a combination of all three.

Approach 1: CPM-Based (Cost Per Mille Comparison)

The simplest approach: calculate what it would cost to buy the same number of impressions through advertising.

Formula: EMV = (Total Impressions / 1,000) × Average CPM

Worked example — UGC: A customer posts a photo on Instagram tagging your restaurant. The post receives 2,500 impressions (views). Your average CPM for Instagram advertising (what you pay per 1,000 impressions) is $12.

EMV = (2,500 / 1,000) × $12 = $30

That single customer post is worth $30 in equivalent advertising exposure.

Worked example — Multiple pieces of content: Over one month, 40 customers create content through your participation system. Their posts collectively generate 120,000 impressions across Instagram, TikTok, and Facebook. Your average CPM across these platforms is $10.

EMV = (120,000 / 1,000) × $10 = $1,200

The participation system generated $1,200 worth of advertising-equivalent exposure in one month — at a fraction of the cost of actually spending $1,200 on ads.

Strength: Simple to calculate. Uses readily available data (impression counts and known CPM rates).

Limitation: Treats all impressions as equal. A customer post that reaches 2,500 people who trust the creator is actually worth more than a paid ad reaching 2,500 strangers, because trust increases conversion. CPM-based EMV is a conservative estimate — the real value is higher.

Approach 2: Engagement-Based (Cost Per Engagement Comparison)

A more nuanced approach: calculate what it would cost to generate the same level of engagement through advertising.

Formula: EMV = (Total Engagements) × Average Cost Per Engagement (CPE)

Worked example — UGC engagement: A customer's TikTok video about your winery receives 500 likes, 40 comments, and 80 shares. Average cost per engagement on TikTok (what you pay for each like, comment, or share through ads) is $0.15.

Total engagements = 500 + 40 + 80 = 620

EMV = 620 × $0.15 = $93

Worked example — Review engagement: A Google Review of your restaurant receives 15 "helpful" votes and influences an estimated 30 additional booking inquiries over three months. The cost per lead through Google Ads in your category is $8.

EMV = 30 leads × $8 = $240

Strength: More accurate than CPM because engagement signals active interest, not just passive exposure. An engaged impression is worth more than a passive one.

Limitation: Engagement costs vary significantly by platform, industry, and campaign quality. The CPE used in the calculation must be representative of your actual advertising costs to produce a meaningful EMV.

Approach 3: Conversion-Based (Attributed Revenue Comparison)

The most directly valuable approach: calculate the revenue generated by earned media actions and compare it to the cost of acquiring equivalent revenue through advertising.

Formula: EMV = Attributed Revenue × (1 / Advertising Conversion Rate) × Cost Per Click

Worked example — Referral value: A customer refers three friends through your participation system. Two of them visit and spend $85 each. Your Google Ads cost per click is $2.50 and your website conversion rate is 3%.

Revenue from referrals = 2 × $85 = $170

To generate $170 in revenue through advertising: $170 / average order value ($85) = 2 customers needed. At a 3% conversion rate, you need 67 clicks to get 2 customers. At $2.50 per click, that costs $167.50.

EMV of the referral = $167.50

The referral generated customer acquisition that would have cost $167.50 through advertising.

Worked example — Review impact on local search: A steady stream of 20 new Google Reviews over two months improves your local search ranking, resulting in an additional 150 website visits and 12 new bookings. Your Google Ads cost per acquisition is $35.

EMV = 12 bookings × $35 = $420

The review stream generated $420 in acquisition-equivalent value.

Strength: The most business-relevant calculation. Directly ties earned media to revenue outcomes.

Limitation: Requires attribution — the ability to connect a specific earned media action to a specific business outcome. Without a tracking system, conversion-based EMV relies on estimation.

Applying EMV to UGC

User-generated content is often the largest component of a business's earned media value because it is frequent, visual, and distributed across social platforms.

What a single UGC post is worth

A customer posts a photo of their meal at your restaurant on Instagram. The post reaches 1,800 followers, receives 120 likes and 8 comments. Using CPM-based calculation at an average Instagram CPM of $12:

EMV = (1,800 / 1,000) × $12 = $21.60

Using engagement-based calculation at an average CPE of $0.20:

EMV = (120 + 8) × $0.20 = $25.60

The true value is somewhere between these two figures — and likely higher, because the post reached people who trust the creator, not strangers targeted by an algorithm.

What a UGC programme is worth

A restaurant with an active participation system generates 60 pieces of customer content per month. Average reach per post is 2,000 impressions with 100 engagements. Average CPM is $11, average CPE is $0.18.

CPM-based EMV = (60 × 2,000 / 1,000) × $11 = $1,320/month

Engagement-based EMV = (60 × 100) × $0.18 = $1,080/month

Combined monthly EMV range: $1,080–$1,320

Annual EMV: $12,960–$15,840

This is the advertising-equivalent value of content that customers created because the participation system made it easy and rewarding to do so.

Why UGC EMV is actually higher than CPM suggests

CPM-based EMV is conservative because it treats a customer post reaching 2,000 people as equivalent to an ad reaching 2,000 people. In practice, the customer post is worth more because:

Trust premium: Consumer trust in UGC is 2–3x higher than trust in advertising. A trusted impression converts at a higher rate than an untrusted one.

Attention premium: Customer content appears in personal feeds alongside friends' posts, where it receives more attention than advertising content that users are trained to ignore.

Persistence premium: An ad stops running when the budget runs out. A customer post stays on their profile indefinitely, continuing to generate impressions and engagement over time.

Applying EMV to Reviews

Reviews generate earned media value through two mechanisms: direct influence on purchase decisions and indirect influence on search visibility.

Direct influence value

Each review influences the purchase decisions of future customers who read it. The Spiegel Research Center found that displaying reviews increases conversion rates by 270%. For a business that receives 1,000 website visitors per month, this means:

Without reviews: 1,000 visitors × 2% conversion = 20 customers

With reviews: 1,000 visitors × 5.4% conversion = 54 customers

34 additional customers per month attributable to reviews. If the average customer value is $60, the monthly review-attributed revenue is $2,040. Annual: $24,480.

This is the EMV of your review profile — the conversion lift that would not exist without those reviews.

Search visibility value

Google's local search algorithm incorporates review quantity, recency, and ratings as ranking factors. A business that moves from position 7 to position 3 in local results can see a 300%+ increase in clicks. For a tourism business receiving 500 monthly Google Business Profile impressions:

Position 7 click-through rate: ~3% = 15 clicks/month

Position 3 click-through rate: ~11% = 55 clicks/month

40 additional clicks per month from improved ranking. At a Google Ads equivalent of $3 per click, the search visibility EMV is $120/month or $1,440/year.

Individual review value

The marginal value of each new review depends on the current review profile. For a business with 50 reviews, each new review has high marginal value because it significantly improves the profile. For a business with 500 reviews, each new review has lower marginal impact on conversion but maintains recency (which Google rewards) and keeps the review profile active.

A reasonable estimate for the direct EMV of a single new Google Review for a local business is $15–$50 per year in conversion lift and search visibility improvement, depending on the current review profile and the competitiveness of the local market.

Applying EMV to Referrals

Referrals have the most directly calculable EMV because the attribution is clearest: a specific customer referred a specific person who made a specific purchase.

The basic referral EMV calculation

A customer refers a friend. The friend visits and spends $100. The business's average customer acquisition cost through advertising is $45.

Referral EMV = $45 (the advertising cost that was avoided)

If the referred customer becomes a repeat customer with a lifetime value of $400, the long-term referral EMV is even higher — the business acquired a $400 customer for the cost of the referral reward (typically $10–$20).

The network effect multiplier

Referral EMV compounds because referred customers refer others. If Customer A refers Customer B, who refers Customer C, the EMV of Customer A's original referral includes not just B's value but a fraction of C's value as well. The Wharton School found that referred customers have a 16% higher lifetime value and are themselves more likely to refer — creating a multiplier effect that increases the original referral's EMV over time.

Referral programme EMV

A restaurant with a participation system generates 15 referrals per month. Average referred customer spend per visit is $75. Average customer acquisition cost through advertising is $40.

Monthly referral EMV = 15 × $40 = $600

Annual referral EMV = $7,200

This is the acquisition cost the business avoided by generating customers through referrals rather than advertising.

Why Participation Systems Make EMV Measurable

The historical challenge with EMV is that earned media is difficult to measure. Customer content scatters across platforms. Reviews appear on sites the business does not control. Word-of-mouth recommendations happen in private conversations. The exposure is real but the data is fragmented.

Participation systems solve this by creating a single tracking infrastructure for all earned media actions:

Content is tagged and tracked. When a customer creates content through the participation system, the post's reach, engagement, and attribution are captured. The business knows which customer created it, how many people it reached, and whether it drove any measurable downstream actions.

Reviews are connected to identities. Each review is tied to a known customer profile, enabling the business to see the relationship between review submission, visit history, and future referral activity.

Referrals are attributed. Every referred visitor is tracked from the referral link through to their first visit and beyond, providing precise conversion and lifetime value data for the referral channel.

All actions are unified. Content, reviews, and referrals appear in a single customer profile — providing a complete view of each customer's earned media contribution and enabling accurate, first-party data-backed EMV calculations.

Without a participation system, EMV is estimated. With one, it is measured. The difference between estimating and measuring EMV is the difference between guessing at the value of customer contributions and knowing it precisely enough to optimise investment decisions.

EMV Benchmarks by Industry

EMV varies by industry based on content volume, platform distribution, and customer engagement rates. These benchmarks provide context for evaluating your own earned media performance.

Tourism and hospitality

Tourism businesses typically generate high EMV because travel experiences are inherently visual and shareable. A well-managed participation system at a tourism destination can generate $2,000–$5,000 per month in earned media value through UGC, reviews, and referrals combined. Destination-level participation networks can generate significantly more because the earned media benefits extend across multiple businesses.

Restaurants

Restaurants generate EMV primarily through reviews and visual UGC. An active participation system generating 20+ Google Reviews and 40+ pieces of social content per month typically produces $1,000–$3,000 in monthly EMV. Restaurants with strong visual presentation (plating, ambiance, presentation) tend to generate higher EMV per piece of content.

Events and festivals

Events generate concentrated EMV bursts. A three-day festival with a participation system can generate $5,000–$15,000 in earned media value during the event itself, with additional value from post-event content and reviews that sell tickets for the next edition. The EMV density per attendee at events is the highest of any business type because attendees create content prolifically and reach their networks simultaneously.

Creators and musicians

For creators, EMV is generated by fan activity — shares, reaction videos, playlists adds, and recommendations. A creator with 10,000 engaged fans who actively share content can generate $500–$2,000 in monthly EMV, depending on the platform and engagement level. Fan engagement strategies that incentivise sharing directly increase EMV.

How to Increase Your EMV

EMV is not fixed. It responds to systematic investment in the participation systems that generate earned media.

Increase participation volume

The most direct lever. More participants creating content, leaving reviews, and referring friends generates more earned media. Increasing participation rates from 5% to 15% of visitors roughly triples EMV — and the relationship is close to linear at this scale because most participation actions are independent.

Increase content quality and reach

Higher-quality content reaches more people. A well-composed photo with an engaging caption outperforms a quick snapshot. Participation systems that provide content prompts, templates, or guidelines help customers create content that generates more impressions and engagement per piece.

Increase review volume and velocity

More reviews improve both direct conversion (more social proof) and search ranking (more Google visibility). A steady stream of reviews — 10–20 per month for most local businesses — maintains both benefits. Gaps in review flow allow the profile to stagnate, reducing both conversion lift and search position.

Increase referral conversion

The EMV of a referral programme depends not just on how many referrals are made but on how many convert. Ensuring that the referred visitor's first experience is exceptional, that the onboarding process is smooth, and that the referral incentive is attractive to both parties increases conversion rate — which multiplies the EMV of every referral made.

Repurpose earned media into other channels

Customer content captured through participation can be reused (with permission) in advertising creative, email marketing, website galleries, and social media — amplifying its value beyond the original organic reach. UGC-based ads perform better and cost less than studio-produced creative, compounding the EMV by extending earned media into paid channels.

The EMV of a Participation System: A Complete Example

To illustrate how EMV compounds, here is a complete calculation for a hypothetical restaurant using a participation system.

Monthly participation metrics:

50 customers create social content (average 2,000 impressions, 80 engagements per post)

25 new Google Reviews submitted

10 referrals that convert into new customers

UGC EMV:

CPM-based: (50 × 2,000 / 1,000) × $11 = $1,100

Engagement-based: (50 × 80) × $0.18 = $720

Review EMV:

Conversion lift (conservative): 25 additional converted visitors × $35 acquisition cost = $875

Search visibility improvement: $150/month (estimated based on ranking improvement)

Referral EMV:

10 referrals × $40 acquisition cost = $400

Referral lifetime value premium: 10 × ($400 LTV × 16% premium) = $640

Total monthly EMV: $3,885

Total annual EMV: $46,620

This is the advertising-equivalent value generated by the participation system — exposure, engagement, and acquisition that the business would otherwise have to purchase. Against a typical participation system cost, the ROI is substantial and improving, because EMV compounds over time as content accumulates, reviews build, and the referral network expands.

Frequently Asked Questions

What is Earned Media Value (EMV)?

Earned Media Value is a metric that assigns a dollar value to organic, non-paid brand exposure generated by customers — including user-generated content, reviews, referrals, social mentions, and word of mouth. It represents what the business would have to spend on advertising to achieve equivalent exposure, engagement, or acquisition.

How do you calculate EMV?

Three common approaches: CPM-based (total impressions divided by 1,000, multiplied by average cost per thousand impressions), engagement-based (total engagements multiplied by average cost per engagement), and conversion-based (attributed revenue compared to the advertising spend required to generate equivalent outcomes). The most accurate EMV calculations use a combination of all three.

What is the difference between earned media and paid media?

Paid media is exposure purchased through advertising — you pay per impression or click and the reach stops when spending stops. Earned media is exposure generated organically by customers and other third parties through content, reviews, referrals, and word of mouth — you do not pay per impression and the exposure compounds over time. Earned media is more trusted and more durable than paid media.

Why is EMV important?

EMV makes the value of customer-generated content, reviews, and referrals tangible and comparable to advertising spend. Without EMV, businesses tend to undervalue earned media because it does not appear on a credit card statement. EMV reveals that active participation systems often generate more value per dollar invested than advertising, and that value compounds over time.

What is the EMV of a Google Review?

The EMV of a single Google Review includes both direct conversion impact (the review influences future visitors' decisions) and search visibility impact (reviews improve local search ranking). A reasonable estimate for a local business is $15–$50 per review per year in combined conversion lift and search visibility improvement, depending on the current review profile and market competitiveness.

What is the EMV of a referral?

The EMV of a referral is approximately equal to the customer acquisition cost that was avoided. If your average acquisition cost through advertising is $40 and a customer refers a friend who becomes a customer, the referral EMV is $40. If the referred customer has a 16% higher lifetime value than average, the long-term referral EMV is proportionally higher.

How do participation systems increase EMV?

Participation systems increase EMV by making earned media generation reliable and scalable. They provide prompts that increase participation rates, tracking that makes EMV measurable, and rewards that sustain participation over time. Businesses using participation systems typically see 5–10x more earned media actions than those relying on organic generation alone.

Can EMV be negative?

Not directly — EMV measures the value of positive exposure. However, negative reviews, critical social media posts, and poor word of mouth represent negative earned media that reduces the value of positive earned media. The net earned media position (positive minus negative) is what matters. Participation systems that generate a steady stream of positive reviews and content create a buffer against negative exposure.

How does EMV relate to the participation economy?

In the participation economy, earned media is the primary output of customer participation and EMV is how its value is quantified. Every participation action generates earned media, and the participation flywheel ensures that earned media compounds over time. The participation economy model is built on the insight that systematically generating earned media through customer participation is more efficient and sustainable than purchasing exposure through advertising.
