• ad_impression
• ad_click
• in_app_purchase
• ecommerce_app_purchase
• session_start

Browser
Name and version number of the user's browser (for example, Microsoft Internet Explorer 11). For browsers that auto-update, such as Google Chrome, no version number is displayed. 

“In-app browser” is a browser embedded within an app.

• Winner: The bid won because it wasn’t rejected for any reason.
• Outbid: The bid lost to another candidate in the auction.
• Floor: The bid lost because its CPM was below the seller's reserve.
• Optimized pricing: The bid was below the floor price set by optimized pricing.

• Other: The bid lost for another reason, such as URL filtering.

TCF vendor ^(Deprecated)  
The name of the ad technology provider as it appears on the Global Vendor List (GVL).

Any ad technology provider name value returned here is representative of bid rejections specific to that ad technology provider, while a value of "(Not applicable)" indicates no bid rejections due to one or more ad technology providers.

Combine this dimension with the "Bid rejection reason" dimension for more insights.

Reports only historical data after its deprecation on February 22, 2024.

Reports only historical data after its deprecation on February 22, 2024.

Note: If the creative is part of a creative set, the "Creative ID" column may show the creative set ID. For technical details, view the SOAP API "CREATIVE_ID" entry.

Creative size ^(Deprecated)  
Size of creative that served to the ad slot request. Creative size doesn't represent the actual size of a creative being served. This dimension represents the "Targeted Ad Unit Size" of the creative which is served. Since a Creative size can only be associated with filled impressions, this dimension is not compatible with the Unfilled impressions metric.

When the Creative size dimension is included in a report, companion delivery that is otherwise rolled up under master delivery is surfaced, so you may see higher totals than expected.

Creative size (delivered)
The size of the ad slot where creatives are served from Ad Manager or Ad Exchange. This value may differ from the creative size reported in Ad Exchange. Possible values include:

• Audio: Audio ads 
• Fluid: Google rendered Native & Fluid ads
• Interstitial: Interstitial ads
• Native: Custom rendered native ads
• Video/Overlay: Video ads
• <width>x<height>: Fixed-size ads

Any other values show as "Unknown".

Note: This dimension can't appear in the same report as the "Unfilled impressions" metric. They are incompatible.

Secure signal delivery ^(Beta) 
Reports if secure signals were sent to the bidder who won the impression. Values include:

• Sent to winner
• Not sent to winner

Secure signal sharing is a processor feature that lets publishers pass obfuscated signals (such as user IDs) to third-party bidders on RTB bid requests. 

Shows how including secure signals and sending them to bidders can impact metrics, such as Total impressions and Total CTR. 

Likely, the Bidder hasn't chosen to receive the signal(s) if you see a combination of:

• "Secure signal delivery = Not sent to winner" with
• "Secure signal presence = Present", and
• You've successfully completed your secure signals implementation.

The method used for counting impressions. Possible values include:

• Downloaded: Follows IAB count on download (Digital Video Ad Measurement Guidelines 2009).
• Begin to render: An impression is counted after creative assets have begun rendering. Follows IAB begin to render (Digital Video Ad Measurement Guidelines 2018).
• Unknown: An impression from Ad Exchange or AdSense (like, a non-Ad server impression), or an Ad server impression from before the introduction of this dimension in June, 2020.

Sometimes, there may be discrepancies or negative numbers when the impression counting method dimension is used. This can occur when a begin-to-render ping is received, but a downloaded ping is not received.

Master and Companion creative
Type of creative that served, when trafficked as a creative set.

For video master and companion creatives, master ads play within the video player; companion ads, usually display, serve to non-video ad slots in conjunction with the master.

Active View measurement source
The measurement source of a given metric. Possible values include:

• Measured: The data for the metric was directly measured by client code that either Google controls or with which Google has intimate familiarity, or it uses OMID data from client code that was certified by Google or IAB Tech Lab.
• Provided: The data for the metric uses OMID data or other publisher-provided signals that were not certified by Google or IAB Tech Lab.
• Inferred: The data for the metric was inferred using sound judgment; however, it was not directly measured on the client. The inferred metric may originate from Google or a third party.

Optimization type ^(Beta) 
View a breakdown of data by the following optimization types:

• First Look
• Optimized competition
• Target CPM

Shows performance distributed by serving restriction. If an ad call can be subject to multiple restrictions, only the first match from the order below will be reported. Reporting figures won't overlap.

• Limited ads: Traffic where only limited ads can serve. This matches ad calls that include either the parameter ltd=1, gad_has_consent_for_cookies=0, or a TC string which does not signal the purpose 1 consented while signalling legal bases for the purposes 2, 7, 9, and 10.
• Restricted data processing (RDP): Includes traffic where the publisher requested restricted data processing using the tagging parameter or the network control.
• Non-personalized ads (NPA): Includes traffic where the publisher requested non-personalized ads using the tagging parameter or the network control.
• Basic ads: Traffic where only IAB TCF v2.0 basic ads are eligible to serve. This matches users whose provided TC string includes consent for purpose 1 and legal bases for purposes 2, 7, 9, and 10, but no consent for purposes 3 or 4.
• Personalization disabled: Traffic where personalization was disabled by the mobile device’s user controls, other user personalization opt-out controls, or other cases where personalization wasn't feasible.
• No restriction: Traffic without any of the restrictions listed above.

Some ad requests may fall into multiple categories in this list. In these cases, the ad request is sorted into the first applicable category according to the order shown here.

Policy restrictions are not included in the Serving restrictions dimension and should be reviewed in the Policy center.

The unified pricing rule (UPR) used to set the price applied to programmatic demand.

Shows the best eligible UPR, which may not be the applied UPR or the rejection reason. Other factors or rules could cause a bid's rejection.

Yield partner tag
Name of a yield partner in a yield group, including the yield group name and "Ad source ID" value. Example: "MyYieldGroup-MyYieldPartner ID: 123456789".

For Ad Exchange, the value "Ad Exchange" is displayed. Note that metrics for the "Ad Exchange" yield partner tag are counted once for each applicable yield group Ad Exchange is part of.

Predicted viewability bucket ^(Beta) 
The estimated percentage of viewability based on an ad slot's historical and environment data, grouped into buckets. Possible values include:

• ≥50%
• 20% to 49%
• ≤19%
• Unknown

User identifier status ^(Deprecated)  
Indicates whether a valid user advertising identifier (a third-party cookie or device ID) was present on a given ad request. 

Possible values include:

• Active: A user identifier was present and active.
• Restricted: A user identifier was present, but its usage was restricted by how cookies may be used. For example, personalization is not allowed.
• Missing: A user identifier wasn't present.

In comparison to "Third-party ID status," "User identifier status" first checks permissions, then ID presence. Because it checks permissions first it may have the value "restricted," even if no ID is present.

This dimension was previously called "User cookie status."

Ad experiences
Type of Ad experiences used to serve the creative. Possible values are "Expanded ad (full screen)" or "(Not applicable)."

Ad technology provider
The ad technology provider (ATP) associated with the bid. ATP reports only if a bid is rejected due to lack of vendor consent. Otherwise, this dimension shows "Not applicable."

Compatible only with "Bids" and "Average bid CPM" metrics.

Ad technology provider domain
The domain of the ad technology provider (ATP) associated with the bid.

Compatible only with "Bids" and "Average bid CPM" metrics.

Advertiser domain
Shows performance by advertiser URL. For example, Big Soda Pop Co. might map to a domain name of delicious.cola.com.

Provides more transparency into advertisers whose identities are not otherwise available. This dimension sometimes makes large-volume reports run more slowly.

• Web caches and others: Domains that are associated with ad servers are grouped here, including Ad Manager and third-party, because we only report on the top-level domain. So if an ad server domain includes redirect parameters, we truncate the full URL, even though the request is valid and may be associated with revenue and impressions.

  You may want to combine this dimension with the "Advertiser (classified)" dimension, as we can often identify the advertiser associated with such domains.

• Unknown: This dimension shows the top 10,000 advertiser domains across Ad Exchange and Open Bidding, ranked by revenue. Any advertiser beyond this limit is placed into the "unknown" category.

Reports that use the “Advertiser domain” dimension will show 100% Ad Exchange Coverage for all rows except "(unknown)". For this reason, Ad Exchange Ad Requests and Ad Exchange Coverage should be disregarded for those rows.

In some scenarios, such as RTB ads, the advertiser domain may be one of multiple submitted domains and we don't know the specific creative chosen to be served. In this case, the advertiser domain reported is one randomly chosen from the list of possible domains.

"Not Applicable" indicates incompatibility with Ad server, AdSense, and Mediation demand channels.

Advertiser vertical
Shows performance by specific advertiser categories, such as Arts & Entertainment and Travel & Tourism. Helps understand performance across different advertiser segments.

Buying agency ^(Deprecated)  
Shows performance by buying agency. Not all buyers pass the agency name. As a result, if we don’t show a name, we may display "(unknown)" or "(No agency)."

Reports that use the "Buying agency" dimension will show 100% Ad Exchange Coverage for all rows except "(Unmatched ad requests)." For this reason, Ad Exchange Ad Requests and Ad Exchange Coverage should be disregarded for those rows.

"Not Applicable" indicates incompatibility with Ad server, AdSense, and Mediation demand channels.

Is First Look
Returns TRUE when First Look transacted. Available only for bids in Open Auction. Not supported for Preferred Deals or Private Auctions. 

First Look pricing rule
Reports the First Look pricing rule. Where an item is eligible for both the First Look pricing rule and Unified pricing rule, the two rules are reported separately (in First Look pricing rule and Unified pricing rule dimensions) to help you determine which rule has the higher floor.

Applies to Ad Exchange and Open Bidding. Shows "(Not applicable)" for other demand channels.
 

Shows publishers the performance of Preferred Deals, Private Auction, and Programmatic Guaranteed (Standard and Sponsorship) broken out by a Programmatic deal name. 

Shows "(Not applicable)" if no Preferred Deal, Private Auction, or Programmatic Guaranteed was involved. 

Previously called “Deal name.”

Shows performance of Preferred Deals, Private Auction, and Programmatic Guaranteed (Standard and Sponsorship). 

The Programmatic deal ID is a system-generated number used to identify a deal between a buyer and a publisher. Shows "0" if no Preferred Deal, Private Auction, or Programmatic Guaranteed was involved.

Note: Some buyers may submit multiple bids at the same price for a single auction through different auction package deals, which aren't reported in Google Ad Manager. For these types of bidding, the Programmatic deal ID value is the auction package deals IDfor Open Auction demand channel.

Previously called “Deal ID.”

Secure signal name (delivered) ^(Beta) Reports the names of the secure signals that were sent to the bidder who won the impression.

Protected Audience API delivery ^(Beta)

The Agency value is present only when the agency is set up. Additional values include:

• "Unknown" is shown when an agency isn't set up.
• "(Not applicable)" is shown for demand channels other than Ad Exchange.

Supported agencies include: Omnicom, Dentsu, Publicis, Havas, and GoodWay Group.

The spend per agency only displays when it comes from a DSP that is making proper bid response declarations about the buyer for whom they're bidding.

DSPs that support such declarations are DV360, Yahoo, and Amazon.

Ad Exchange product
Shows the performance of specific Ad Exchange products. For example: Display, Video, Mobile-In app, and Ad Exchange for Games. This dimension is only visible if you use another Ad Exchange product, such as Video or Mobile.

Use the "Ad Server Targeted Impressions" and "Ad server impressions" metrics to differentiate between targeted and untargeted impressions.

Includes all ad sizes in each ad request, accurately reflecting ad requests with multiple inventory sizes.

The size is displayed in the format "wxh" with multiple sizes separated by comma (for example, 300x250, 600x300v). You can apply filters to this dimension to only include certain sizes. Video ad request sizes are appended with "v", such as "640x480, 300x250v".

How this dimension differs from "Ad request size":

• Reports on all ad sizes in each request to reflect multi-size inventory more accurately.
• Broader compatibility with other dimensions and metrics.
• Compatible with filters to limit the sizes included.
• Format: WxH (no spaces, comma-separated).

Ad request sizes
All ad unit sizes included in an ad request display in the report on the same line. This reflects how many impressions are available for a given tag. For example, if your ad request (or, tag) contains 2 sizes, such as 300x250, 300x600, there will be one row in the report with both sizes, and they are separated by a comma. Video ad request sizes are appended with "v", such as "300x250v".

PPID presence ^(Deprecated)  
Indicates whether a valid PPID (Publisher-provided identifier) was present on a given ad request. Covers both reservation and programmatic traffic. Possible values include:

• Present: A valid PPID was present
• Missing: A PPID was not present or had an invalid form

Secure signal presence ^(Beta) 
Reports the presence of secure signals in the ad request. Values include: 

• Present
• Missing

Secure signal sharing is a processor feature that lets publishers pass obfuscated signals (such as user IDs) to third-party bidders on RTB bid requests. 

Shows how including secure signals and sending them to bidders can impact metrics, such as Total impressions and Total CTR.

Likely, the Bidder hasn't chosen to receive the signal(s) if you see a combination of:

• "Secure signal delivery = Not sent to winner" with
• "Secure signal presence = Present", and
• You've successfully completed your secure signals implementation.

Traffic source ^(Beta) 
Understand if a requested query is designated as purchased. Values include:

• Purchased: Traffic redirected from properties other than owned (acquired or otherwise incentivized activity)
• Organic: Direct URL entry, site search, or app download
• Undefined: Value not set in the GPT or mobile SDK

Note: Publishers must set the traffic source to "Purchased" or "Organic" on the ad request to see those values in reporting. If no value is set, we'll report "Undefined."

Core compatibility

URL
Shows publishers the performance of their domains, subdomains or pages for URLs defined under "Inventory."Ad requests are only counted for URLs that have been defined under "Inventory."

Ad type
Shows the performance of different ad types. Possible ad types in reporting include:

Not all of these ad types will appear on your inventory. 

Applies to Ad Exchange, Open Bidding, and AdSense. Shows "(Not applicable)" for other demand channels.

Dynamic allocation
Shows performance by different inventory sources.

• No Dynamic Allocation: (direct requests, or an unknown ad server) Ads served by Ad Exchange outside of dynamic allocation. This includes impressions that are served directly on a page or via another ad server that does not support dynamic allocation.
• Dynamic Allocation with no Ad Manager competition: (regular backfill) Backfill by Ad Exchange where it did not receive a reserve price by the publisher’s ad-server via dynamic allocation.
• Dynamic Allocation with Ad Manager competition: Backfill by Ad Exchange where it was able to beat the reserve price sent by the publisher’s ad-server via dynamic allocation.

Applies to Ad Exchange and Open Bidding. Shows "(Not applicable)" for other demand channels.
 

Auto-refreshed traffic
Indicates if the traffic is from auto-refreshed ad requests. Values include:

• Refreshed: Traffic that is auto-refreshed, which refers to the action of serving or changing advertising or content in an automatic manner when a publisher calls auto refresh Google Publisher Tag (GPT) API on the ad request.
• Not refreshed: All other traffic.

Secure signal name (presented) ^(Beta) 
Reports the names of the secure signals sent in the ad request.

PPID status
Indicates the valid PPID (Publisher provided identifier) status on a given ad request. Covers both reservation and programmatic traffic. This dimension only reports on PPID. Possible values include:

Possible values include:

• Active: A user identifier was present and active.
• Restricted: A user identifier was present in the ad request but personalization was not allowed.
• Missing: A user identifier wasn't present.

In comparison to “User identifier status,” “Third-party ID status” first checks presence, then permissions. Because it checks presence first it may have the value "missing," regardless of whether the user has opted out of personalization. 

First-party ID status
Indicates whether a first-party user identifier was present on a given ad-request. This dimension only reports values based on first-party IDs and does not include PPID.

Possible values include:

• Active: A user identifier was present and active.
• Restricted: A user identifier was present in the ad request but personalization was not allowed.
• Missing: A user identifier wasn't present.

Primary personalization ID type
Shows impressions coverage by the ID type selected for personalization. Each impression will only be attributed to a single ID type. For reservations this is the ID type that may have been used for line-item audience-list targeting. For auction it is the ID type forwarded to the bidder. Note that this dimension is a proxy for the ID type that is most likely attributed to the impression (that is, an ID might not be sent to the bidder or used in bidding).

Possible values include:

• Third-party IDs: Third-party cookie or device ID
• PPID: Publisher provided identifier
• First-party IDs: First-party identifiers
• No personalization: No personalization was possible, but an ID was chosen for other purposes, such as frequency caps. Note that this classification will be phased out in favor of “non-personalizable IDs” and “personalization restricted.” Shows only for data occurring before April 16, 2024. 
• Non-personalizable IDs: An ID that can’t be used for personalization was present. Other uses, such as frequency caps, were possible.

The values of "interstitial" and "no content" are populated automatically based on the declared inventory type. The video placement dimension only applies to backfill traffic. 

Continent
Continent associated with the IP address from the ad slot request.  

Possible values include Unknown, Africa, Americas, Asia, Europe, and Oceania.

Assignment
Assignments help you define revenue sharing or ad serving relationships with partner publishers. Depending on your permissions, you can select from some or all of the following types of assignments, below.

• Track: Define a revenue share agreement with a publishing partner for display or video ads. Revenue share is expressed in terms of a percentage value on the assignment.
• Redirect: Send either a percentage or an absolute number of video ad requests to a partner publisher. The redirect is handled through a third-party VAST tag.
• Share: Share specified video inventory with a partner Ad Manager publisher. Your partner can then book line items directly against that inventory in their own Ad Manager network.

A publisher with whom you have an agreement to share ads and revenue.

Organize your partners by label. Labels allow you to later report by label and leverage other ad serving features.

Date
Daily breakdown of data. In Ad Manager, the data is shown in an extended format, such as Monday, January 18, 2016. The exported format is more compact, for example M/D/YY.

Note: The exported date format is based on the language and/or location associated with the Google account of the person creating the report. In reports created by other users, such as scheduled reports, the exported date format may differ from the format in reports created by you.

Video ads not targeted to specific content using the cmsid and vid parameters appear as "Not applicable" with this dimension. To limit your report to only content-specific traffic, apply the Request type filter, set to is any of > Video tag when reporting on this dimension.

This will show "Not applicable" when a request comes for content that hasn't been ingested or requests don't match ingested content.

Content bundle
Video groups assembled and targeted based on filters or by selecting individual videos, or both. The content bundles are automatically updated when new content is ingested with matching metadata.

Reports with this dimension show all bundles where content appeared, not only the targeted bundles.

Video ads not targeted to specific content using the cmsid and vid parameters appear as "Not applicable" with this dimension. To limit your report to only content-specific traffic, apply the Request type filter, set to is any of > Video tag when reporting on this dimension.

To limit results to video-only traffic, filter your results using the Request type filter, set to is any of  Video tag.

To limit results to video-only traffic, filter your results using the Request type filter, set to is any of  Video tag.

VAST version ^(Beta) 
The numerical version of a VAST creative that is returned, which may be useful in determining which version of VAST is requested on your ad tags, or if you distribute different ad tags to different players or partner inventory. Possible versions are: VAST 2, VAST 3, VAST 4, and Not applicable (for non-video requests).

For redirects, this is not the VAST version from the third-party ad server.

This dimension can be combined with all video dimensions, including content metadata, date and time, request type, ad unit and placement, and all delivery dimensions. It is compatible with total impressions metrics; sell-through metrics; viewership, error, and interaction metrics.

Video ad request duration

Inventory types (expanded)
Values match the Inventory type dimension available in the Overview Home dashboard.If comparing, be sure the date range in your report matches the date range on the Overview dashboard. 

Note: Video takes precedence over any other value, for example, if there is an in-stream video impression on a desktop device, it will be attributed to in-stream video and not desktop web.

Values include:

• AMP: User is viewing the ad on an Accelerated Mobile Page, which has been designed to load mobile web content faster.
• App: User is viewing the content through a mobile app on their smartphone or tablet. Note that Ad Manager identifies mobile apps via use of the SDK. Publishers using simplified URL tags to make requests for an app may see inconsistent results.

Shows performance broken out by the technology used to request the ad. This allows for advanced troubleshooting, such as investigating discrepancies between served and downloaded impressions. Possible values are:

• AMP Ad tag
  An impression is attributed to a request from an <amp-ad> tag. This tag allows AMP Ads to load faster than standard ads or ads from other tag types. If this value is something other than "AMP Ad tag" (such as "Google Publisher Tag" or "Other"), you're likely running ads from a custom domain. You may want to replace them with <amp-ad> tags, so AMP Ads can load faster.

Branding type
Shows either "Branded," "Semi-Transparent," or “(Unmatched ad requests)." The value depends on the amount of information about the Publisher’s page sent to the buyer who purchased the impressions.

Shows performance by general groups of inventory. Possible values are:

• Web: User is viewing the content through a PC or laptop computer, or from their mobile or tablet browser.
• App: User is viewing the content through a mobile app on their smartphone or tablet. Note that Ad Manager identifies mobile apps via use of the SDK. Publishers using simplified URL tags to make requests for an app may see inconsistent results.
• AMP: User is viewing the ad on an Accelerated Mobile Page, which has been designed to load mobile web content faster.
• Other: Ad Manager can't detect where the user is viewing the content.

Rendering SDK

App ownership status ^(Beta) 
Easily filter reports by my claimed apps with App ownership status. Values include the following:

• Owned means you've successfully claimed the app as yours.
• Not owned means you haven't claimed the app as yours.
• Not applicable means the App ID is not available.

The app must be confirmed through app readiness before you claim the app as owned. The app then goes through an approval process where the app receives a status.

App status is at the time of analysis, not at the time of the ad event.

Yield group 
Name of the group of ad networks or exchanges, called a yield group, used for Mediation and Open Bidding.
