How to plan a connected TV advertising campaign

What to take away

Most teams start with the platform and the spot length. That is backwards, and it is why so many connected TV tests end with a flat reach curve and no agreed definition of success.
Write the objective first, then the measurement, then the budget, and only then the channel. A connected TV advertising strategy is a sequence of decisions, not a media list.
Connected TV is a reach and brand medium in most plans, so judge it on incremental reach, completed views and brand measures rather than last-click response.
Compliance and creative approval take time. Build them into the schedule rather than treating them as a final check.
Use a scoring rubric to compare options on the same criteria before you sign anything.

Start with the objective

The most common connected TV mistake is treating the channel as a cheaper version of linear television. Teams buy a package, run a thirty second spot, then ask the agency why nothing moved.

Before you brief anyone, write one sentence that names the business outcome and the time frame. For example: "Grow awareness among 25 to 44 year olds in Manchester by eight points over two quarters." That sentence rules out half the inventory on offer and makes the rest easier to price.

Objectives differ in what they demand of the medium. A reach objective needs broad, addressable supply and a frequency CAP you can defend. A consideration objective needs longer creative and a landing experience that works on a television screen.

It also helps to read how other advertisers have approached the same choices. The ISBA knowledge hub collects planning and buying resources written for advertisers rather than agencies, which is useful when you are setting the brief yourself.

If your objective cannot be measured with the data you already have access to, change the objective or change the measurement. Do not run the campaign and hope.

Set the measurement first

Measurement is where connected TV plans quietly fail. The platform reports completed views, the analytics tool reports sessions, and the two numbers never reconcile because they count different things.

Which measurement will you trust?

Which measurement source will you trust?

Yes

Platform-reported delivery -> agree cadence and owner

Third-party verification -> define completed-view threshold

Decide in advance which you will trust: platform-reported delivery, a third-party verification partner, or your own incrementality test. Ask providers such as BARB, Nielsen, Kantar and Comscore which audience, campaign or brand measures they can supply for your inventory; coverage differs. Then agree the reporting cadence and who owns the number.

Agree the vocabulary too. A view on one platform is not a view on another, and the completed-view threshold can be set anywhere between a few seconds and the full spot. Naming that threshold in the plan stops two teams reporting two different numbers in the same meeting.

Brand lift studies need enough volume to say anything. If your budget is small, a simple geo holdout will usually tell you more than a survey that cannot reach significance.

For a working method of sequencing measurement, budget and creative over a first quarter, the ninety day plan for connected TV advertising sets out a week by week structure you can adapt to your own planning cycle.

Write the success threshold down before launch. "At least four incremental reach points against the linear plan" is a testable statement. "Improved brand health" is not.

Budget and buying routes

Connected TV inventory is bought in three broad ways: through a broadcaster's streaming platform, through a demand side platform, or through a managed service from a media owner or agency. UK broadcaster and streaming options include ITVX, Channel 4, Sky, Netflix, Amazon Prime Video and Disney+; availability and buying access vary by service. Programmatic buying can use DSPs such as Google Display & Video 360 (DV360), The Trade Desk or Amazon DSP.

Typical budget split

Proven premium supply70%
Testing new placements30%

Broadcaster video on demand usually brings premium content, tighter brand safety and simpler measurement, at a higher cost per thousand impressions. Programmatic brings scale and targeting, with more work on supply quality.

Ask what the fee covers before you compare prices. Two quotes at the same cost per thousand can include very different amounts of targeting, reporting and optimisation, and the cheaper headline is often the more expensive plan once the add-ONS are priced.

The reasons media planners give for using broadcaster video on demand are worth reading in full before you choose. Thinkbox sets out the reasons for using BVOD in audience and effectiveness terms rather than price alone.

Budget shape matters as much as budget size. A common split is roughly 70 per cent to proven, premium supply and 30 per cent to testing new placements, though the right ratio depends on how much you already know about your audience.

For a worked example, a team paying £400 a month for a small test could reasonably expect a few hundred completed views, not a measurable brand shift. Set expectations against the spend.

Creative for the big screen

Television creative is watched, not scrolled past. A spot that opens with three seconds of logo and a legal line will lose the room before the message arrives.

Big screen creative checks

Front-load brand and point
Keep text readable at viewing distance
Check soundbar and phone speaker
Watch cut with volume down
Build two or three variants
Allow four to six weeks production

Front-load the brand and the point. Keep text large enough to read at typical viewing distance. Check how the spot sounds on a soundbar and on a phone speaker, because streaming audiences do both.

Sound is the most common failure. Many viewers keep the volume low while they do something else, so the spot has to work visually as well as audibly. Try watching your own cut with the volume down.

Where you run the same campaign across linear and streaming, resist the temptation to cut the streaming version shorter without a reason. The IAB UK principles for creative best practice are a useful checklist for the discipline of matching format to placement.

Build two or three variants rather than one. Rotation reduces fatigue and gives you a read on which message holds attention.

Allow four to six weeks for production, clearance and trafficking on a new spot. If your campaign starts sooner than that, you are choosing from existing assets.

Rules, data and consent

UK connected TV advertising can fall under different rules depending on where the ad appears. The ASA administers the BCAP Code for broadcast advertising and the CAP Code for non-broadcast advertising; Ofcom's Broadcasting Code applies to editorial content on licensed TV services, not ad clearance.

Compliance checks before launch

Check ICO for personal data duties
Apply age and scheduling rules
Match advertising codes to placement
Review UK digital strategy context
Clear data terms with platforms

If you are buying addressable inventory, you are likely processing personal data. Check the UK data protection law that applies, including UK GDPR and the Data Protection Act 2018; PECR may also apply to cookies or similar technologies. The ICO is the UK's data protection regulator.

For broadcaster video on demand, confirm with the publisher which advertising code and clearance route applies. Clearcast provides pre-clearance for TV ads, and broadcaster requirements can differ; check age-restricted products, scheduling and targeting against the relevant code before booking.

Government policy also shapes what platforms can offer and how data flows across borders. The UK digital strategy sets out the wider policy direction for the digital economy, which is context worth knowing when you negotiate data terms.

For a practical walk through the specific rules and approvals, the UK rules and compliance guide for connected TV advertising covers the checks that most often delay a launch.

Common planning mistakes

Three patterns show up again and again in plans that underperform.

Planning mistakes to avoid

Buying reach you already have
Measuring with last-click attribution
Treating first campaign as verdict
Over-targeting narrow segments

The first is buying reach you already have. If your linear campaign already covers most of the target audience, connected TV should be planned as incremental reach, not as a mirror of the same buy.

The second is measuring with the wrong tool. Last-click attribution will almost always make connected TV look weak, because the viewing device is rarely the conversion device.

The third is treating the first campaign as a verdict. A single flight with one creative and no control group tells you very little. Read the common connected TV advertising strategy mistakes before you decide the channel does not work.

A fourth, quieter mistake is over-targeting. Narrow segments raise cost per thousand and shrink the pool, which is the opposite of what a reach medium needs.

A scoring rubric

Use the table below to score each option out of five in every row. Weight the rows to match your objective, then compare totals. The rubric is a decision aid, not a forecast.

Scoring rubric criteria

Objective fit
Incremental reach
Measurement
Brand safety
Creative fit
Cost efficiency
Compliance
Learning value

Criterion	What good looks like	Score (1-5)
Objective fit	The route delivers the specific outcome you wrote down
Incremental reach	Adds viewers your existing plan does not already reach
Measurement	Independent verification and a defined success threshold
Brand safety	Known content standards and transparent placement reporting
Creative fit	Formats match the assets you can actually produce
Cost efficiency	Cost per thousand and cost per completed view are defensible
Compliance	Data use, consent and clearance are all covered
Learning value	The test produces a result you can act on next quarter

Score the options before you see the final pricing. Pricing tends to anchor the conversation, and a rubric you fill in afterwards is not a rubric.

Choosing between channels

Most advertisers do not choose connected TV instead of linear, search or social. They choose how much of each, and in what order.

A useful discipline is to compare routes on the same two axes: how many people only this route can reach, and how well this route can prove it worked. Routes that score low on both should not be in the plan.

Agency research on how campaigns are planned and evaluated can sharpen this comparison. The IPA knowledge centre publishes effectiveness material drawn from UK agency practice, which is a helpful counterweight to platform data.

Where budgets are tight, sequence rather than spread. One channel done properly for a quarter beats four channels each running for three weeks.

For a structured way to compare routes against objectives, the connected TV advertising strategy framework sets out the trade-offs in a single view.

Building the channel mix

Within connected TV itself, the mix of broadcasters, streaming services and platforms changes what you can buy and how you can target.

Exclusive inventory on one service may be the only way to reach a specific programme audience. Broad programmatic supply may be the only way to hit a cost per thousand target at scale.

Decide which of these matters more for this campaign, and be explicit about what you are giving up. A plan that tries to maximise reach, minimise cost and guarantee context at the same time will not deliver any of the three.

Frequency management is part of this. Across several platforms, the same viewer can be counted several times, so set a CAP at the plan level and reconcile it in reporting.

The connected TV advertising channel strategy guide works through how broadcasters, platforms and programmatic routes differ in practice.

Governance and review

Set a review point before the campaign starts. Two weeks in is usually too early for brand measures but late enough to catch delivery and frequency problems.

Agree who can change the plan mid-flight and what has to be true for them to do it. Without that, small delivery issues turn into emergency calls.

Keep a written record of the objective, the success threshold and the result. It becomes the input to next quarter's rubric, and it stops the same debate recurring.

Common questions

How much should a first connected TV test cost?

There is no universal figure, and anyone quoting one without knowing your category is guessing. A practical approach is to fund a test large enough to produce a readable result on your chosen measure, and to treat the first flight as learning spend rather than a performance buy.

Should connected TV sit in the brand budget or the performance budget?

In most UK plans it sits in the brand budget, because the medium is bought for reach and attention rather than direct response. If you need it to carry a performance target, set that target on a measure the medium can actually influence.

How long before results appear?

Delivery data is available within days, but brand measures typically need a full flight plus a comparison period. Plan on at least one quarter before drawing conclusions about whether the channel works for you.

Do we need a third party measurement partner?

Not always, but you do need a measurement method you trust and can explain. If platform reporting and your own analytics disagree, a verification partner usually pays for itself in avoided argument.
