When to Use Connected TV Advertising Surveys

What to take away

Connected TV advertising surveys are useful when a planner needs a sampled answer about viewing, ad recall or attitudes that delivery logs cannot supply. They do not identify who actually saw an ad unless the design can match respondents to valid exposure data; interviews explain motivations, while dashboards report delivery.

What changed in the streaming ad market

Two shifts matter. Connected TV inventory is routinely traded programmatically through platforms such as Microsoft Advertising, whose ad products cover video and connected TV alongside search and display. Delivery data now tells you how often an ad ran, not which household saw it.

Second, on-demand advertising sits within the broadcast advertising framework. The BCAP Code (the Broadcast Code), administered by the Advertising Standards Authority (ASA) under Ofcom's co-regulatory framework, sets standards for ads in broadcast and on-demand services. Its Misleading advertising rules matter when survey findings support an advertising claim: the claim must be substantiated. A questionnaire is not itself an advertisement, but recall questions should be neutral and should not prompt a particular answer.

When should you use a survey instead of interviews?

Use a survey when the answer is a number. What share of adults in the North West watched ad-supported streaming last month? How many would pay for an ad-free tier? Structured questionnaires produce percentages you can put in a plan.

Interviews answer the question behind the number. The Connected TV advertising customer interviews need a written scoring rubric article covers how to run them without leading the participant, which matters when you are testing creative routes or price sensitivity. Most teams run both: the survey ranks, the interviews explain.

When should you use panel or platform data instead?

If the question is about delivery, use the ad server or a relevant audience measurement source. Reach, frequency and completion rates are measured, not recalled. Asking viewers to remember impressions will undercount; a survey can measure reported recall, but that is not the same as delivery reach.

Panels suit trend work: a single survey is a snapshot, while a repeated panel can show movement over time. BARB is the UK television audience measurement service to check for relevant viewing data; Nielsen and Comscore are other measurement providers to investigate, but confirm that their specific service covers the UK CTV services and audience you need. These sources are not substitutes for a survey when the question is about attitudes. Treat survey findings as a baseline and platform data as the running score.

What does survey research cover?

Survey providers such as YouGov, Ipsos and Kantar can be asked to quote for CTV audience research, but do not assume a general online panel can identify ad-exposed viewers. Ask who recruits the sample, whether it comes from an online access panel or a dedicated media panel, and how CTV use or exposure is screened. The survey-tool reviews and comparison methods can help assess platform functions; a licence alone does not show that the sample is suitable.

Ask two questions before you buy. Can you export raw responses, so the data can be re-weighted later? Does the tool support quotas by region, since England-only campaigns need splits national panels may not guarantee?

How does the choice change your answers?

The trade-off is simple: a survey gives you a number and takes away the detail.

How do you size the sample?

There is no universal number. A national read typically needs around 400 completed responses, which gives a margin of error of roughly five percentage points at the 95% confidence level. A regional cut needs 400 within that region, not 400 overall.

Costs split in two. The £400 monthly survey licence is an illustrative example, not a UK market benchmark; recruitment would still need separate funding, and panel costs can exceed the licence itself. The How do you research the audience for connected TV advertising? guide covers how sampling sits inside a quarterly planning cycle, so it is worth reading before you commit. Decide the sample first, then compare quotes.

When should you test the ad itself?

Creative testing is a separate exercise from audience research. Thinkbox publishes its “How to test TV advertising” guide, covering pre-testing and in-market measurement. Use a survey to describe the audience and a test design to judge the ad.

Common questions

Can a survey measure incremental reach?

Not reliably on its own. Incremental reach is a delivery metric, so it belongs with platform or panel data. A survey can tell you whether viewers remember an ad, which is a different question.

How long should fieldwork run?

One to two weeks is typical for a consumer study. Recall decays, so keep the gap between exposure and questioning short when recall is the measure.

Do I need a separate survey for each region?

Only if you need regional estimates. A national sample of 400 will not support a reliable read for one English region, so add quotas or fund a booster sample.

Is a survey enough on its own?

Rarely. Pair it with interviews to explain the numbers and platform data to track delivery.
