Digital Out-Of-Home (DOOH) Metrics Glossary

As media formats continue to evolve, advertisers need consistency and comparability to efficiently reach consumers with messages that speak to them and engage them in the right time and place. As Digital Out-of-Home (DOOH) becomes an increasingly popular medium for marketers and agency-side planners and buyers, IAB’s DOOH Committee has come together to evaluate commonalities between terms in the measurement realm. We have identified unique terms to the DOOH space in this DOOH Metrics Glossary.

This interactive guide aims to serve as a reference for planners, buyers, and strategists who are looking to engage with DOOH media. We hope this effort will simplify the consideration and planning process by creating a simple set of terms that are commonly utilized by sellers and players across the space.

We intend for this Glossary to be an updated resource for the entire advertising community. Is there a DOOH term we’re missing? Have a question, or a suggestion? Don’t hesitate to reach us at dooh-info@iab.com.

Impressions

Served Impression

An ad that was reported to have begun to render at the screen. Note that in the vast majority of DOOH experiences, all ads (when served) are fully viewable for the entirety of the play. In the digital media world, this term is commonly known as a “play”.

Viewable Impression

In online/digital media, a served ad impression can be only be classified as a “viewable impression” if the ad meets all of the following criteria: it was contained in the viewable space of the browser window, it is in an in-focus browser tab, and it meets pre-established minimum percent of ad pixels within the viewable space and the length of time the ad is in the viewable space of the browser. It is recognized that an “opportunity to see” the ad exists with a viewable ad impression, which may or may not be the case with a served ad impression.  (Source: MRC Viewable Ad Impression Measurement Guidelines Ver. 2.0)

Note: In the Digital Out of Home (DOOH) landscape where there are no individual “browsers” per se, a served ad impression can be classified a “viewable impression” if the ad meets all of the following criteria: it was contained in the viewable space of the screen, it is in an in-focus ad unit that is either Full screen or Partial screen, and it meets pre-established minimum percent of ad pixels within the viewable space and the length of time the ad is in the viewable space of the screen. It is recognized that an “opportunity to see” the ad exists with a viewable ad impression, which may or may not be the case with a served ad impression.

Audience Impression

A unit of measure that includes the total number of people with an opportunity to see (aka traffic), notice, and dwell time, calibrated to the media’s spot length. It can also be explained as the total number of times people passing a digital out-of-home display are likely to notice a message. This concept is sometimes referred to as “Visibility Adjusted Contact”, or “VAC”.

Audience Reach Measurement

A term that provides a count of the total number of people or machines that get ads. In DOOH scenarios, the expected application of Audience Reach Measurement is to count people.

Audience Reach Measurement also refers to a guideline developed by industry bodies that standardizes the measurement of machine based-measures (unique cookies, unique devices, unique browsers) and people-based measures (unique users or visitors). It is critical, and a compliance requirement, that the audience reach measurement organization does not misrepresent machine-based measurements as people-based measurements. The measure’s status as either a people-based or a machine-based measure should be clearly disclosed. For specifics and additional information, please review section 1.2 of the MRC/IAB Audience Reach Measurement Guidelines, https://www.iab.com/wp-content/uploads/2015/06/AudienceReachMeasurementGuidelines.pdf  

Common DOOH Terms

Audience Composition

The demographic, socioeconomic, or behavioral profile of the network’s audience that is inclusive of the percentage of the total audience falling in each segment.

Coverage

The geographic area covered by network installations.

Cost Per Thousand

The cost (price) to deliver 1,000 ad impressions on displays in a market.
 
Acronym: 
CPM

Cost Per Ratings Point

The cost of one rating point in any geographically defined market.
 
Acronym: 
CPP

Dwell Time

The length of time an individual is in a Screen Exposure Zone which is a location from which the screen is visible and, if appropriate, audible. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1)

Exposure

Presence in the defined Screen Exposure Zone while content is deemed to be viewable, though this does not require that the content be viewed or listened to. Exposure is also often referred to as Opportunity-to-See. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1)

Frequency

The number of times the target audience is typically exposed to content, advertising, or a specific ad, in the defined time frame. Frequency represents the average exposure when used in conjunction with cumulative reach estimates, though it can also be reported on the basis of specific exposure levels when evaluated in the context of discrete reach estimates through frequency distribution analyses. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1) In a similar vein, Effective Frequency refers to the number of exposures necessary to make an impact and attain communication goals.

Gross Rating Point

A term used to measure the size of an audience reached by a specific media vehicle or schedule. In the DOOH landscape, GRP means the total number of impressions delivered, expressed as a percentage of a market population. One rating point represents impressions equal to 1% of the market population. In the calculation of GRPs, total impressions must first be reduced to the in-market impressions of individuals who live in the defined market and are part of that market’s population base. A frequently referenced term with GRPs is Target Rating Points (TRPs), which is the sum of the ratings generated by a segment may be called Target Audience GRPs or more simply TRPs.
 
Acronym: 
GRP

Notice

The percentage of respondents who claimed to have noticed a screen.

Media Unit

A unit defined by the DOOH network, used to describe the physical device on which a DOOH ad unit will play. Most often for digital place-based networks, a media unit is a single screen, however in locations where multiple screens are combined to portray content that is larger than one screen, the entirety of the group of screens may be referred to as a single media unit.

Message Duration

The interval of time when a DOOH message is viewable.

Reach

The net (unduplicated) count or percent of the defined universe of the target audience exposed to content, advertising, or a specific ad, in a Screen within a defined time frame. This time frame can be a day, week, or month, or even less-frequent time periods although more frequent reports are generally desirable to users. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1)

Screen

A device or medium designed to deliver Digital Place-Based, Digital Out-of-Home, and/or Advertising content whether it be video, audio, or both.

Target

Any audience reflecting the most desired consumer prospects for a product or service, defined by age, sex, race, ethnicity or income; or their combinations for any geographic definition. Expanded targets include purchasing, behavioral, and audience segmentations.

Unique Traffic

The unduplicated audience that has an opportunity to see any message during a reporting period.

Universe

A geographic universe or coverage definition stated on the basis of population amounts is required for Digital Place-Based / Out-of-Home Networks subject to measurement. These may be customized (or limited) based on the specific attributes of the network and the associated Venue Traffic. In some cases a customized universe can be stated or a general population estimate (e.g., US Census estimates) for media comparability purposes. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1, w/o the “Out-of-Home” reference in the first section)

Venue

The place and location of the advertising network and screens. Examples include supermarkets, office buildings, gas stations, and other places where consumers can be found. (Source: MRC Digital Place-Based Audience Measurement Standards Version 1)
