Pricing Models

AdCP supports multiple pricing models to accommodate different advertising channels and business objectives. Publishers declare which pricing models they support, and buyers select from available options.

Publisher-Declared, Buyer-Selected Model

How It Works

Publishers declare pricing options in their products via pricing_options array (each with unique pricing_option_id)
Buyers discover available options through get_products
Buyers select a specific option when creating a media buy via pricing_option_id
Delivery is measured according to the declared delivery_measurement provider

Key Benefits

Flexibility: Publishers can offer multiple pricing models for the same inventory
Currency Support: Publishers specify supported currencies; buyers must match
Market Standards: Each channel (TV, video, display, performance) can use its natural pricing unit
Clear Expectations: Both parties agree on pricing before campaign launch

Measurement & Source of Truth

Measurement Provider as Source of Truth

The product declares the measurement provider, and the buyer accepts that provider as the source of truth for the buy. Publishers specify their measurement provider in the product:

{
  "product_id": "premium_video",
  "delivery_measurement": {
    "provider": "Google Ad Manager with IAS viewability verification",
    "notes": "MRC-accredited viewability measurement. 50% in-view for 1 second (display) or 2 seconds (video)."
  }
}

Common Measurement Providers:

Ad Servers: Google Ad Manager, Freewheel, SpringServe
Attention Metrics: Adelaide, Lumen, TVision
Third-Party Verification: IAS, DoubleVerify, Scope3
TV/Audio Measurement: Nielsen, Comscore, iSpot.tv, Triton Digital
DOOH: Geopath, Vistar, Place Exchange

By accepting the product, buyers agree to use the declared measurement provider as the authoritative source for delivery metrics.

Best Practices

For Publishers:

Clearly identify your measurement provider (ad server and any third-party verification)
Explain your measurement methodology in plain language
For DOOH, specify your audience measurement source (e.g., Geopath, venue sensors)

For Buyers:

Review the measurement provider before committing budget
Ensure the provider meets your campaign requirements
Negotiate audit rights in contracts if needed

Supported Pricing Models

CPM (Cost Per Mille)

Cost per 1,000 impressions - Traditional display advertising pricing. Use Cases: Display, native, banner advertising Example:

{
  "pricing_option_id": "cpm_usd_guaranteed",
  "pricing_model": "cpm",
  "rate": 12.50,
  "currency": "USD",
  "is_fixed": true,
  "min_spend_per_package": 5000
}

Billing: Charged per 1,000 ad impressions served

vCPM (Viewable Cost Per Mille)

Cost per 1,000 viewable impressions - Payment only for impressions meeting MRC viewability standard. Use Cases: Display, native, video advertising with viewability guarantee Viewability Standard: MRC (Media Rating Council) standard requires:

Display ads: 50% of pixels in-view for at least 1 continuous second
Video ads: 50% of pixels in-view for at least 2 continuous seconds

Example:

{
  "pricing_option_id": "vcpm_usd_guaranteed",
  "pricing_model": "vcpm",
  "rate": 18.50,
  "currency": "USD",
  "is_fixed": true,
  "min_spend_per_package": 5000
}

Billing: Charged per 1,000 viewable impressions (impressions meeting MRC viewability threshold). Viewability is measured by the declared measurement provider. Measurement Requirements: Publishers should declare their viewability measurement provider in the product’s delivery_measurement field. Common providers include IAS (Integral Ad Science), DoubleVerify, MOAT, and Google Active View.

CPCV (Cost Per Completed View)

Cost per 100% video/audio completion - Payment only for fully completed views. Use Cases: Video campaigns, audio ads, pre-roll video Example:

{
  "pricing_option_id": "cpcv_usd_guaranteed",
  "pricing_model": "cpcv",
  "rate": 0.15,
  "currency": "USD",
  "is_fixed": true
}

Billing: Charged only when viewer completes 100% of the video/audio ad. Completion is measured by the declared measurement provider.

CPV (Cost Per View)

Cost per view at threshold - Payment when viewer reaches publisher-defined threshold. Use Cases: Video campaigns with shorter completion requirements Example:

{
  "pricing_model": "cpv",
  "rate": 0.08,
  "currency": "USD",
  "is_fixed": true,
  "parameters": {
    "view_threshold": 0.5
  }
}

Billing: Charged when viewer reaches threshold (e.g., 50% completion, 30 seconds) Parameters:

view_threshold: Decimal from 0.0 to 1.0 (e.g., 0.5 = 50% completion)

CPP (Cost Per Point)

Cost per Gross Rating Point - Traditional TV/radio buying metric. Use Cases: Connected TV, linear TV, radio, audio streaming Example:

{
  "pricing_model": "cpp",
  "rate": 250.00,
  "currency": "USD",
  "is_fixed": true,
  "parameters": {
    "demographic": "A18-49",
    "min_points": 50
  },
  "min_spend_per_package": 12500
}

Billing: Charged per rating point delivered to target demographic Parameters:

demographic: Target demographic (e.g., “A18-49”, “W25-54”, “M35+”)
min_points: Minimum GRP commitment required

Metrics Reported:

grps: Total Gross Rating Points delivered
reach: Unique individuals reached
frequency: Average frequency per individual

Measurement Requirements: CPP pricing requires certified demographic measurement. Publishers should declare their measurement provider:

{
  "pricing_model": "cpp",
  "rate": 250.00,
  "delivery_measurement": {
    "provider": "Nielsen DAR",
    "notes": "Panel-based demographic measurement for A18-49. GRP reports available weekly."
  }
}

Common Measurement Providers for CPP:

Nielsen DAR/TV: Industry-standard TV measurement
Comscore: Campaign Ratings for CTV
iSpot.tv: Advanced TV analytics
Triton Digital: Audio/streaming measurement

Buyers should verify the measurement provider meets their campaign requirements before accepting CPP deals.

CPC (Cost Per Click)

Cost per click - Performance-based pricing for engagement. Use Cases: Direct response campaigns, search ads, social advertising Example:

{
  "pricing_model": "cpc",
  "rate": 1.50,
  "currency": "USD",
  "is_fixed": false,
  "price_guidance": {
    "floor": 0.50,
    "p50": 1.20,
    "p75": 2.00
  }
}

Billing: Charged only when user clicks the ad

Flat Rate

Fixed cost - Single payment regardless of delivery volume. Use Cases: Sponsorships, takeovers, exclusive placements, branded content Example:

{
  "pricing_model": "flat_rate",
  "rate": 50000.00,
  "currency": "USD",
  "is_fixed": true
}

Billing: Fixed cost for the entire campaign period

Digital Out-of-Home (DOOH) Pricing

DOOH advertising uses existing pricing models—typically CPM or flat_rate—with optional parameters to describe the inventory allocation.

Basic Concepts

CPM for DOOH: Priced per thousand impressions, where impressions are calculated based on venue traffic (e.g., Geopath data)
Flat rate for DOOH: Fixed cost for specific duration or allocation (hourly, daily, or exclusive takeover)

Simple Example: Billboard Takeover

{
  "product_id": "billboard_takeover",
  "name": "Premium Billboard - 24 Hour Takeover",
  "pricing_options": [{
    "pricing_model": "flat_rate",
    "rate": 50000.00,
    "currency": "USD",
    "is_fixed": true
  }],
  "delivery_measurement": {
    "provider": "Geopath",
    "notes": "Venue traffic data updated monthly. Estimated 2.5M impressions over 24 hours."
  }
}

DOOH Parameters (Optional)

Publishers may include additional parameters to describe DOOH inventory allocation:

duration_hours: Duration for time-based pricing
sov_percentage: Share of voice (% of available plays)
daypart: Specific time periods (e.g., “morning_commute”)
venue_package: Named collection of screens

Note: DOOH measurement and buying practices vary by market. Publishers should clearly explain their measurement methodology and inventory allocation in the product description and delivery_measurement field.

Multi-Currency Support

Publishers can offer the same product in multiple currencies:

{
  "product_id": "premium_video",
  "pricing_options": [
    {
      "pricing_option_id": "cpm_usd_guaranteed",
      "pricing_model": "cpm",
      "rate": 45.00,
      "currency": "USD",
      "is_fixed": true
    },
    {
      "pricing_option_id": "cpm_eur_guaranteed",
      "pricing_model": "cpm",
      "rate": 40.00,
      "currency": "EUR",
      "is_fixed": true
    },
    {
      "pricing_option_id": "cpm_gbp_guaranteed",
      "pricing_model": "cpm",
      "rate": 35.00,
      "currency": "GBP",
      "is_fixed": true
    }
  ]
}

Buyer Responsibility: Buyers must select a currency that the publisher supports.

Fixed vs. Auction Pricing

Fixed Pricing (`is_fixed: true`)

Publisher sets a fixed rate
Rate is guaranteed and predictable
Common for guaranteed inventory
Requires rate field

Auction Pricing (`is_fixed: false`)

Final price determined through auction
Publisher provides price_guidance with floor and percentiles
Common for non-guaranteed inventory
Buyer submits bid_price in media buy request

Auction Example:

{
  "pricing_option_id": "cpcv_usd_auction",
  "pricing_model": "cpcv",
  "currency": "USD",
  "is_fixed": false,
  "price_guidance": {
    "floor": 0.08,
    "p25": 0.10,
    "p50": 0.12,
    "p75": 0.15,
    "p90": 0.18
  }
}

Buyer Selection Process

Each package specifies its own pricing option, which determines currency and pricing model:

{
  "buyer_ref": "campaign_001",
  "start_time": "2025-01-01T00:00:00Z",
  "end_time": "2025-01-31T23:59:59Z",
  "promoted_offering": "Q1 Brand Campaign",
  "packages": [{
    "buyer_ref": "pkg_ctv",
    "product_id": "premium_ctv",
    "format_ids": [{"agent_url": "https://creatives.adcontextprotocol.org", "id": "video_30s"}],
    "pricing_option_id": "cpcv_usd_auction",
    "budget": 50000,
    "pacing": "even",
    "bid_price": 0.16
  }]
}

How it works:

Package selects pricing_option_id from product (e.g., “cpcv_usd_auction”)
Pricing option determines currency, pricing model, and fixed vs auction
Package budget is in the pricing option’s currency
Auction-based pricing requires bid_price
Sellers validate currency compatibility across packages

Reporting Metrics by Pricing Model

Different pricing models report different primary metrics:

Pricing Model	Primary Metric	Secondary Metrics
CPM	impressions	clicks, ctr, spend
vCPM	viewable_impressions	impressions, viewability_rate, spend
CPCV	completed_views	impressions, completion_rate, spend
CPV	views	impressions, quartile_data, spend
CPP	grps	reach, frequency, spend
CPC	clicks	impressions, ctr, spend
Flat Rate	N/A	impressions, reach, frequency

Example: Multi-Model CTV Product

A publisher offering Connected TV inventory with multiple pricing options:

{
  "product_id": "ctv_premium_sports",
  "name": "Premium Sports CTV",
  "description": "High-engagement sports content on CTV devices",
  "format_ids": [
    {
      "agent_url": "https://creatives.adcontextprotocol.org",
      "id": "video_15s"
    },
    {
      "agent_url": "https://creatives.adcontextprotocol.org",
      "id": "video_30s"
    }
  ],
  "delivery_type": "guaranteed",
  "pricing_options": [
    {
      "pricing_option_id": "cpm_usd_guaranteed",
      "pricing_model": "cpm",
      "rate": 55.00,
      "currency": "USD",
      "is_fixed": true,
      "min_spend_per_package": 15000
    },
    {
      "pricing_option_id": "cpcv_usd_guaranteed",
      "pricing_model": "cpcv",
      "rate": 0.22,
      "currency": "USD",
      "is_fixed": true,
      "min_spend_per_package": 15000
    },
    {
      "pricing_option_id": "cpp_usd_m18-49",
      "pricing_model": "cpp",
      "rate": 300.00,
      "currency": "USD",
      "is_fixed": true,
      "parameters": {
        "demographic": "M18-49",
        "min_points": 50
      },
      "min_spend_per_package": 15000
    }
  ]
}

A buyer could choose CPP pricing if they’re planning TV buys, CPCV if optimizing for engagement, or CPM for reach-based campaigns.
