CTV frequency and household exposure in Australia

CTV frequency describes how many ad impressions are assigned to a reporting unit during a stated period. Household frequency counts impressions assigned to a household; average frequency across reached households is delivered impressions divided by unique households reached. It measures delivery, not verified viewers.

Household exposure means an ad impression is assigned to a household as the reporting unit. A television may be shared, and people may watch across devices and publishers, so an assigned impression does not establish which household member watched.

What counts as CTV in the household

CTV is the device used to watch connected television content. OTT is content delivered over the internet, bypassing traditional pay TV. CTV devices include smart TVs, streaming devices and gaming consoles, so a household may access connected viewing through more than one screen type.

Australian streaming examples span funding models: Netflix, Disney+ and Stan are subscription services, while 9Now, 7plus, SBS On Demand and Tubi are ad-supported. Kayo Sports and Binge are also examples in the Australian streaming landscape. Service labels do not show how often an ad reached a household.

IAB Australia’s 2025 Digital Advertising Landscape Report found that over 80% of Australian households have at least one CTV device. That describes access, not how many households received an ad or how often.

Define the unit before setting a cap

Name the household as the reporting unit; do not say only that a campaign reports CTV frequency. Require the reporting to state how impressions are assigned to households. A device, signed-in user, modelled person and household are not interchangeable units.

Set the reporting window and campaign scope before launch: dates, eligible inventory and whether co-viewing is estimated. Count the impressions assigned to each household within that window. Average household frequency is total delivered impressions divided by unique households reached; it is not a count of verified distinct viewers.

A household frequency cap is the maximum number of assigned impressions allowed per household during a stated window. Read delivered frequency against the same household unit, window and campaign scope; a device-level limit should not be labelled a household cap.

The named Australian measures do not specify a household impression-assignment or deduplication standard, a household-frequency reporting field or format, or a standard household cap.

CTV vs. Traditional TV: Delivery and Measurement

The Australian viewing footprint is changing

IAB Australia’s Australian CTV market investigation, published on 25 November 2020, reported that video advertising grew 15% in FY20 versus FY19 and reached 53% of the general display market. Publishers’ video expenditure share attributed to CTV rose from 23% to 41% over the preceding 15 months.

These figures describe advertising investment, not household viewing, reach or frequency. They are not Australian household exposure measures or frequency benchmarks.

Plan for useful exposure, not a magic number

For a usable report, look for delivered impressions, unique households reached, average household frequency, the dates covered and the cap setting. These figures should use the same unit and window so delivery can be read against the cap.

A 2021 US CTV report by ANA and Innovid, Decoding CTV Measurement: An In-depth Look at Reach, Frequency and ROI, reported average frequency of 4.6 across campaigns. This is a US figure, not an Australian household benchmark or a basis for setting a local cap.

ThinkTV Australia reports that advertisers using both broadcast and CTV inventory can achieve up to 20% incremental reach compared with TV-only campaigns. That is a reach comparison, not a household frequency measure or cap benchmark.

Frequency is a delivery diagnostic, not a verdict on persuasion. Read it alongside creative rotation, completion or attention measures where available, and business outcomes, while recognising the limits of attribution.

Best Practices for Measuring CTV Household Exposure

Inventory changes the exposure environment

CTV ad supply changes with how services fund content. Subscription services have traditionally offered limited advertising, while some platforms introduce ad-supported tiers or hybrid models. Free ad-supported streaming television channels, known as FAST, are supported entirely by advertising and expand the inventory available to advertisers.

CTV combines a large-screen environment with digital delivery, audience targeting and digital measurement. Those capabilities can help plan delivery, but they do not by themselves establish which household members watched an ad.

IAB Australia described the local market as having a number of large premium broadcasters and a healthy supply of quality BVOD content. It said direct deals with these suppliers can help marketers meet their requirements without exposure to open-market bidding environments.
