Agency Commission

Sum of money paid to advertising or media placement agency by outdoor contractors for placing business, usually 10% of the value (gross rate) of the contract of outdoor.

Airport Advertising

Includes internal and external displays of various sizes.

Animation

Animation involves special treatment such as moving units, flashing lights, etc., and is used to gain added attention and awareness. Animation is more commonly used in rotating, permanent or spectacular sites.

Asset

An individual site of any particular outdoor media format.

Audience Accumulation

Reach measure denoting the total number of different people exposed to a medium over a specified period; such as a 1 week measure of a face.

Audience composition

Standards definition (Common OOH terms): The demographic, socioeconomic, or behavioural profile of the network’s audience that is inclusive of the percentage of the total audience falling in each segment.
Standards definition (Audience targeting terms): Attributes of the audience of a given campaign or set of campaigns. Very often based on demographic attributes, eg 44 per cent female / 56 per cent male, or geographic attributes.

Audience contacts

Audience contacts represent how many people have travelled past or waited near the sign. These can be represented as total people, ie OTS, or visibility adjustment may also apply to create LTS. A person is counted once for each single journey past the sign. Audience contacts can be reported over time across multiple days as reach and frequency.

Audience impressions

Audience impressions represent how many views of the advertiser’s campaign has occurred as people have travelled past or waited near the sign. A person may be counted as having viewed the advertiser’s campaign more than once in a single journey if they dwelled long enough to see the same advertiser again. Audience impressions typically include visibility of the sign (to the audience) in the methodology. Audience impressions can be reported over time across multiple days as reach and frequency.

Audience reach percentage

Percentage of an addressable target audience reached by a given campaign.

Australian Advertising Standards Bureau

Average Audience

The average number of individuals viewing a face / campaign or sub group over a given interval (e.g. weekly or monthly).

Average Daily Traffic Count

The outdoor audience is measured by the number of vehicles passing a specific site multiplied by estimated average vehicle occupancy. Traffic counts are available from State Road or Transport authorities and estimates of vehicle occupancy for different types of roads are also available from the same source. All counts provided from this information should be for one-way viewing. Such traffic counts do not include pedestrian audience that may be significant when sites are within a CBD or at a retail shopping location. Occupancy rates vary by location but is generally between 1.45 and 1.75 per vehicle.

Includes profiles based on movement / visits to particular destinations, eg shopping centres, recreational areas, and sporting venues. Behavioural and transactional data profiles may or may not refer to a profile about unique users.

Behavioural segments 

Segmenting audiences that are defined by previous behaviours, frequently their recent online behaviour, or offline purchases and places they frequented. For example, an auto advertiser may seek to reach anyone who’s visited an auto review site in the last 30 days, or transactional data that deliver behavioural attributes of luxury car buyers, who pass specific locations.

Circulation

Circulation (potential viewers) is the foundation for determining the advertising value of outdoor sites. Outdoor circulation is based on traffic volume. There are three types of people in this volume: occupants of cars, pedestrians and mass transit passengers. Generally outdoor circulation figures will only reflect people in vehicles. Occupancy rates vary by State, by type of location and time of day.

Code of Ethics

The Outdoor Advertising Association of Australia (Inc.) has a voluntary code adopted upon membership to the Association, pledging member companies to operate for and in the public interest.

Commercial share of time

Cost per minute 

The cost (price) to deliver a minute of total advertisement play independent of audience. As with cost per play, the effective audience period should be taken into account for any analysis. Cost per play (and cost per minute) is determined by the on and off time per screen. However, if agreed by the seller and buyer, the time period of analysis can be modified. This is particularly important as cost per play (and cost per minute) should take into account the effective audience period, eg 95 per cent of Roadside audience is between 6am and 11 pm, so only plays in this period should be used for analysis.

Cost per play 

The cost (price) to deliver an advertisement play. Variations in the advertising play length between locations may exist, as the play length is determined by other factors, eg Roadside is affected by state and local government planning laws and these differ across Australia.

Coverage 

The audience impressions within the geographical area covered by reporting, can sometimes be referred to as reach per cent or 000s.

Cost per Thousand (CPM)

The audience impressions within the geographical area covered by reporting, can sometimes be referred to as reach per cent or 000s.

This allows advertisers to understand the true potential number of viewers of an OOH campaign and not just the number of times the advertisement was shown.

Site Classification

Each advertising face needs to be classified according to its location, format, size and other specific characteristics. Some of these characteristics are used to determine the Likelihood To See (LTS) audience measurement results.

MOVE calculates contacts by first assigning the entire Potential audience to trips that make up the average typical day (i.e. work trips, shopping trips, social trips, education trips etc). Each of these trips has a path through the market place. The relationship between this path and the signage locations with determine which signs the Potential audience sees. If they see at least one sign in the campaign then they are included in Total Reach.
