CTV Advertising: Why Most Brands Are Buying It Wrong

CTV advertising puts your brand in front of audiences on streaming platforms, connected televisions, and over-the-top content, with targeting precision that traditional broadcast never offered. Done well, it closes the gap between the reach of television and the accountability of digital. Done badly, it becomes another line item that looks impressive in a deck and delivers very little in the real world.

Most brands buying CTV right now are doing it badly. Not because the channel is broken, but because they are applying the wrong mental model to it.

What CTV Advertising Actually Is

Connected TV refers to any television set that connects to the internet, whether through a smart TV operating system, a streaming stick, a games console, or a set-top box. CTV advertising is the buying of ad inventory within streaming content viewed on those devices. It sits under the broader umbrella of OTT (over-the-top) advertising, though the terms are often used interchangeably in media planning conversations, sometimes loosely.

The platforms involved include the advertising-supported tiers of Netflix, Disney+, Peacock, Paramount+, and Max, alongside free ad-supported streaming TV services like Pluto TV, Tubi, and Freevee. Roku, Amazon Fire TV, and Samsung Ads operate as both hardware and inventory aggregators. The ecosystem is fragmented, which creates both opportunity and complexity.

What separates CTV from traditional linear TV is the data layer. You can target by household income, purchasing behaviour, content genre, device type, geographic area down to zip or postcode level, and in some cases by first-party audience segments matched against a platform’s own data. That targeting capability is real and it is valuable. It is also frequently oversold.

If you are thinking through where CTV sits in a broader commercial strategy, the Go-To-Market & Growth Strategy hub covers the planning frameworks that make channel decisions like this more defensible.

Why the Performance Marketing Mindset Breaks CTV

I spent a good chunk of my earlier career overvaluing lower-funnel performance. It is an easy trap. The numbers are immediate, the attribution is legible, and it feels like you are in control. What I came to understand, after managing hundreds of millions in ad spend across industries as different as financial services and fast-moving consumer goods, is that much of what performance channels get credited for was going to happen anyway. You are often capturing intent that already existed, not creating it.

CTV is not a performance channel. It never was. When brands try to run it like one, they end up frustrated, because the conversion signal is weak, the attribution path is indirect, and the cost-per-acquisition looks terrible compared to paid search or shopping. That comparison is a category error. You would not judge a billboard by its click-through rate.

The value of CTV sits upstream. It builds familiarity. It creates the mental availability that makes every downstream channel work harder. When someone searches for your brand or clicks your retargeting ad, they are often doing so because something earlier in the chain made your brand feel known and trustworthy. CTV can be that thing. But only if you measure it that way.

This connects to a broader point about how growth actually works. Vidyard’s analysis of why go-to-market feels harder identifies the same pattern: brands optimise for the measurable and underinvest in the things that create demand in the first place. CTV sits squarely in that underinvested category for most mid-market brands.

The Targeting Advantage Is Real, But Creative Kills It

Here is where CTV gets genuinely interesting. The ability to serve a household-income-targeted, genre-contextual, non-skippable 30-second spot to a specific audience segment, at scale, on a television screen, is a meaningful step forward from where broadcast planning was ten years ago. You can build audience segments that would have been impossible to reach efficiently on linear TV.

But targeting is not a substitute for creative. It never is. I have seen brands spend six figures on CTV inventory with audience segments that were genuinely well-constructed, and then fill that inventory with a 30-second ad that was clearly built for digital display, repurposed with a voiceover, and approved by someone who had never watched it on an actual television. The result is an ad that feels cheap, breaks the viewing experience, and actively damages the brand.

CTV is a lean-back environment. The viewer is on a sofa, in a room, often with other people. The screen is large. The audio is on. The ad is, in most placements, non-skippable. That is a privilege. It is also a responsibility. If your creative is not built for that environment, you are not just wasting money, you are creating a negative brand impression at scale.

The brief for a CTV creative should be fundamentally different from a social video brief. You have the viewer’s full attention. You have audio. You have a large canvas. Use them. Tell a story. Create a feeling. Make someone remember your brand exists. That is the job.

Frequency Management: The Biggest Operational Failure

If you talk to anyone who watches a significant amount of streaming content, they will tell you the same thing. They have seen the same ad so many times that they now actively dislike the brand. This is not a perception problem. It is a buying problem.

Frequency capping in CTV is harder than it sounds because the inventory is bought across multiple DSPs, multiple platforms, and multiple supply paths. A household that watches Pluto TV, Tubi, and Peacock in the same week may see your ad on all three, and your campaign may have no mechanism for knowing that. You cap frequency at the platform level and end up with uncapped frequency at the household level.

The brands getting this right are doing a few things. They are consolidating buying through fewer DSPs with cross-platform identity resolution. They are setting household-level frequency caps as a campaign requirement, not an afterthought. And they are actively monitoring frequency data in weekly reviews, not just looking at reach and impressions.

There is also a creative rotation discipline that matters here. Even if you cannot perfectly control frequency, rotating three or four creative executions within the same campaign dramatically reduces the fatigue effect. The viewer may see your brand six times in a week, but if the creative is different each time, the experience is less corrosive.

How to Actually Measure CTV Performance

Measurement is where most CTV conversations fall apart. The platforms offer attribution dashboards that look authoritative and are, in many cases, self-serving. A streaming platform telling you that its inventory drove a lift in conversions is like asking your estate agent whether now is a good time to buy. The incentive structure should make you sceptical.

I have been on the other side of Effie Award submissions where brands claimed extraordinary returns from upper-funnel channels based on attribution models that would not survive five minutes of scrutiny. The measurement looked clean because nobody had asked the hard question: would some of this have happened anyway?

Honest CTV measurement uses a combination of approaches. Brand lift studies, run by independent third parties, measure changes in awareness, consideration, and purchase intent among exposed versus unexposed audiences. Geo holdout tests run the campaign in some markets and not others, then compare outcomes. Search volume uplift in exposed geographies is a useful proxy signal. Incrementality testing, where you deliberately withhold spend from a matched audience group, is the most rigorous approach available.

None of these are perfect. All of them are more honest than last-click attribution or a platform’s own conversion dashboard. The goal is not perfect measurement. It is honest approximation. Forrester’s work on intelligent growth models makes a similar point: growth measurement should inform decisions, not validate them after the fact.

What I would caution against is building a measurement framework that is so complex it becomes a reason to avoid making decisions. Three clean signals, consistently tracked, beat twelve metrics that nobody agrees on.

The Audience Strategy That Actually Works

The most common audience strategy in CTV is retargeting existing customers and known website visitors. It is the easiest to execute, the easiest to measure, and the least valuable from a growth perspective.

Think about it this way. Someone who has already visited your website, or is already a customer, is already in the funnel. Showing them a television-style brand ad is not moving them forward. It is spending premium inventory on an audience that was already warm. You are paying CTV prices to do the job that a retargeting display campaign could do for a fraction of the cost.

The more interesting use of CTV targeting is reaching audiences who do not know you yet. Lookalike audiences built from your best customers. Category-intent audiences who are in-market for what you sell but have not found you. Demographic and behavioural segments that match your ideal customer profile but sit outside your current customer base.

This is where the analogy I keep coming back to becomes relevant. A clothes shop where someone has tried something on is far more likely to result in a purchase than one where they have only browsed the window. CTV is the try-on moment. It creates the familiarity that makes the rest of the funnel work. But that only applies to people who have not yet tried you on. For existing customers, you need a different tool.

The growth strategy implication is significant. If your CTV buy is primarily retargeting, you are using a reach channel as a retention channel. That is an expensive mistake. Rebalancing toward net-new audience acquisition is usually where the real return sits.

Where CTV Fits in a Go-To-Market Plan

CTV is not a standalone tactic. It works best when it is integrated into a broader go-to-market architecture where each channel has a defined role and a clear handoff to the next.

In a well-structured plan, CTV sits at the top of the funnel, creating awareness and mental availability among target audiences. Paid social and YouTube extend that reach and add a layer of engagement. Paid search captures the intent that CTV and social have created. Email and direct channels convert and retain. Each layer is doing a different job, and each is measured against the right benchmark for that job.

The mistake is treating CTV as interchangeable with any other video channel. It is not. The viewing context, the screen size, the audio environment, and the audience mindset are all different from a pre-roll ad on YouTube or a mid-feed video on Instagram. The creative, the targeting, and the measurement should all reflect those differences.

For brands launching into a new market or category, CTV can accelerate the awareness phase considerably. BCG’s work on go-to-market launch strategy highlights that the speed of initial awareness-building is often the determining factor in whether a launch achieves sustainable market position or stalls. CTV can be a meaningful part of that acceleration, particularly for brands with a visual story to tell.

If you are working through how CTV connects to your broader channel architecture, the thinking in the Go-To-Market & Growth Strategy hub covers the planning principles that make those decisions more coherent.

The Inventory Quality Problem Nobody Talks About Enough

CTV inventory is not uniformly premium. The ecosystem includes genuinely high-quality placements within popular streaming content, and it also includes inventory that is barely distinguishable from low-quality display advertising. The difference matters enormously for brand safety, viewer experience, and actual effectiveness.

Programmatic CTV buying, through a DSP without careful inventory curation, can result in your ad appearing in content you would never consciously choose, on devices that are technically connected televisions but are actually tablets or monitors, and in environments where the claimed viewability bears no relationship to reality.

The questions worth asking your media partner or DSP before committing budget: What percentage of the buy is direct deals versus open exchange? How is device verification being handled? What content categories are included and excluded? How is invalid traffic being filtered? If the answers are vague, that is a signal.

The premium publishers, whether that is a direct deal with a major streaming platform or a curated private marketplace, tend to cost more and deliver better. The CPM premium is usually worth paying for the inventory quality, the brand safety, and the audience accuracy. Chasing the lowest CPM in CTV is a reliable way to end up with impressive reach numbers and no discernible business impact.

Pricing strategy in media, like pricing strategy in any market, has a floor below which quality deteriorates rapidly. BCG’s analysis of long-tail pricing dynamics in B2B markets illustrates the same principle: the cheapest option in a fragmented supply chain is rarely the most efficient one when you account for quality variance.

What a Well-Built CTV Campaign Actually Looks Like

When I have seen CTV work well, it tends to share a few characteristics. The brief was written for television, not repurposed from digital. The audience strategy was oriented toward net-new reach rather than retargeting. The buying was consolidated enough to manage frequency meaningfully. The measurement framework was agreed before the campaign went live, not retrofitted afterward. And the team understood that results would take time to show up in the metrics that matter.

That last point is worth dwelling on. CTV operates on a longer feedback loop than performance channels. The awareness it creates takes weeks to manifest as search volume, consideration, and eventual conversion. If you are reviewing CTV performance on a weekly basis against conversion metrics, you will almost certainly kill it before it has had time to work.

A realistic timeline for evaluating CTV effectiveness is a minimum of eight weeks, with brand lift data collected at the four-week and eight-week marks, and search volume and consideration metrics tracked across the full campaign period. Anything shorter is not measurement, it is impatience dressed up as rigour.

The brands I have seen get the most from CTV are also the ones who treat it as a long-term investment rather than a quarterly experiment. They build audience familiarity over time, iterate on creative based on brand lift data, and use the channel consistently enough that it compounds. A single flight of CTV rarely moves the needle. Sustained presence does.

Creator-driven content strategies are starting to intersect with CTV in interesting ways too, particularly for brands trying to make streaming placements feel more native and less interruptive. Later’s work on creator-led go-to-market campaigns explores how brands are integrating creator content into broader channel strategies, and some of those principles translate directly to how CTV creative should be conceived.

The Questions Worth Asking Before You Buy

Before committing budget to CTV, there are five questions that will tell you whether you are ready to use the channel well.

First: do you have creative that was built for a large screen, lean-back environment, with audio, at 15 or 30 seconds? If the answer is no, fix that before you buy the media.

Second: is your audience strategy oriented toward net-new reach, or is it primarily retargeting people who already know you? If it is the latter, reconsider whether CTV is the right tool for that job.

Third: do you have a measurement framework that does not rely solely on platform-reported attribution? If your plan is to look at the dashboard the streaming service provides and call that measurement, you will be disappointed.

Fourth: can you sustain the investment for long enough to see brand-level results? If the budget is only available for four weeks, CTV is probably not the right channel. Put it somewhere with a faster feedback loop.

Fifth: is there alignment internally on what success looks like, and is that definition appropriate for an awareness channel? If the CMO is expecting CTV to drive direct conversions, and the media team knows it will not, that conversation needs to happen before the campaign launches, not after.

Getting those five things right will not guarantee CTV works for your brand. But getting any of them wrong will almost certainly guarantee it does not.
