CTV advertising is a $33 billion market in the US, and that number is growing north of 13% per year. If you’re in B2B marketing and haven’t explored it yet, you’ve probably had one of two reactions: either you’ve looked at CTV and assumed it’s only for consumer brands, or you’ve tested it and found that the targeting felt like a blunt instrument.
Both reactions make sense. Most CTV platforms were built for B2C. The targeting is demographic: age, gender, income, zip code. The measurement is consumer-centric: reach, frequency, video completion rate. That’s fine if you’re selling running shoes. It’s not fine if you’re trying to reach the VP of Procurement at a target account.
But CTV itself is not the problem. The problem is how it’s been packaged. The channel reaches 90% of US households, ads complete at 96% rates, and your target accounts are watching premium streaming content every night. The missing piece was always targeting and measurement built for B2B.
That’s what this guide covers: how CTV advertising actually works, why it matters for B2B, and how account-based targeting changes what’s possible.
What is CTV Advertising?
Connected TV (CTV) advertising is the delivery of video ads to internet-connected television devices. That includes smart TVs, Roku, Amazon Fire TV, Apple TV, gaming consoles, and any other device that streams content to a TV screen.
CTV ads run within streaming content on platforms like Hulu, Disney+, Peacock, ESPN+, and hundreds of smaller networks. They look like traditional TV commercials (15 or 30 seconds, full-screen, sound-on), but they’re bought programmatically with digital targeting and measurement behind them.
The key distinction from traditional TV: connected TV advertising is delivered over the internet, which means every impression is trackable. You know it was served, you know it was viewed, and you can tie it back to targeting criteria. No Nielsen estimates. No hoping the right person was watching.
CTV vs. OTT vs. Linear TV
These terms get used interchangeably, but they’re different:
- CTV (Connected TV) refers to the device. Any TV connected to the internet that can stream content.
- OTT (Over-the-Top) refers to the delivery method. Content delivered over the internet, bypassing traditional cable. OTT includes phones, tablets, and desktops. CTV is specifically OTT on a television.
- Linear TV is traditional broadcast and cable. Scheduled programming, no on-demand. Ads are bought by daypart and program, not by audience.
For B2B advertisers, CTV is where the focus should be. It combines the full-screen, living-room environment of TV with the targeting precision of digital. OTT on phones and tablets has its place, but CTV delivers the attention and completion rates that matter for brand-building campaigns.
Why CTV Matters for B2B
If you’ve spent your career in B2B digital marketing, you’re used to channels like search, LinkedIn, and display. CTV feels unfamiliar. Here’s why it deserves attention.
Your target accounts are watching
Streaming now accounts for nearly half of all TV viewership in the US, according to Nielsen’s December 2025 Gauge report. Your prospects, the decision-makers, budget holders, and buying committee members at your target accounts, are watching Hulu after dinner, streaming ESPN on weekends, catching up on Peacock during the week.
And they’re increasingly watching with ads. 45% of US Netflix households are now on the ad-supported tier. 84% of Peacock subscribers choose the ad tier. For both Netflix and Disney+, 100% of net subscriber growth in 2025 came through ad-supported plans. The ad-free audience is shrinking. The ad-supported audience is where the growth is.
Completion rates dwarf other formats
CTV ads complete at 96% for 30-second spots, per IAB’s video ad completion benchmarks. Compare that to mobile video (69-75%), desktop video (74-83%), and social video (often 10-30%). When your ad runs on CTV, it gets watched. The lean-back, non-skippable viewing environment is fundamentally different from a thumb scrolling past your ad on a phone.
For B2B brands where the message is nuanced (you’re not selling impulse purchases), that completion rate matters. You have 30 seconds of undivided attention from a decision-maker in their living room. That’s a different kind of impression than a banner ad they scrolled past.
CTV drives measurable downstream activity
CTV drives measurable results across the entire funnel, but the path looks different than search or social. The impact shows up everywhere:
- Website visits from target accounts increase after CTV exposure. You can track this at the account level.
- Search activity goes up. Research from the Video Advertising Bureau shows that nearly half of all website visits after TV exposure come through Google search. Your prospect sees your brand on their TV, then searches for you the next day at work.
- Paid channels convert better. Search, social, and display campaigns see improved conversion rates when CTV is running. The brand awareness CTV builds makes prospects more likely to click, engage, and convert when they encounter you on other channels.
- Brand awareness lifts are significant. CTV campaigns deliver roughly 25% lifts in brand awareness according to Comscore research, with 20% lifts in purchase intent.
B2B adoption is accelerating
This isn’t an emerging experiment anymore. B2B brands are moving real budget into CTV, and the ones that started early are already building institutional knowledge about what works: which creative resonates, how to measure incrementality, how to integrate CTV with their ABM programs. The longer you wait, the more ground you cede to competitors who are reaching your target accounts on the biggest screen in the house.
How CTV Targeting Works for B2B
This is where CTV for B2B diverges from the standard playbook. Traditional CTV targeting relies on demographics and behavioral segments. That’s built for consumer brands. B2B needs something different.
Standard CTV targeting (built for B2C)
Most CTV platforms offer:
- Demographic targeting: age, gender, household income, education level
- Geographic targeting: DMA, state, zip code, city
- Behavioral segments: in-market for travel, auto intenders, sports fans
- Contextual targeting: ads placed within specific content categories
These work for reaching consumers. They don’t work for reaching the CFO at a mid-market SaaS company on your target account list. You can’t get there by layering demographic and behavioral segments. The targeting is too blunt.
Account-based CTV targeting (built for B2B)
Account-Based Television flips the targeting model. Instead of starting with audience segments and hoping the right people are in there, it starts with your accounts.
Here’s how it works:
-
Start with your accounts. Upload your target account list to your CTV platform: company names, contacts, firmographic criteria. This is the list of companies you actually want to reach.
-
Match accounts to households. The platform uses identity graph data from third-party providers to match your target companies to the residential addresses of employees at those companies. A VP of Marketing at Acme Corp gets matched to their home address, where they’re streaming content on their smart TV.
-
Serve ads on premium streaming inventory. Your 15 or 30-second spot runs on Hulu, Disney+, ESPN, Peacock, and other premium networks when matched households are streaming. The ad looks and feels like any other commercial. The difference is who’s seeing it.
-
Measure at the account level. After ads run, track which accounts were reached, at what frequency, and what happened next: website visits from those accounts, changes in engagement with sales outreach, pipeline movement.
This isn’t the same as IP-based targeting, which matches company office IP addresses and only works when people are at the office (increasingly rare with remote and hybrid work). Account-based CTV targets the household, which means you reach decision-makers where they actually watch TV.
What this looks like in practice
A cybersecurity company wants to reach CISOs at their top 300 target accounts. They upload their account list. The platform matches those companies to employee households. Their 30-second brand spot runs on premium streaming networks when those households are watching. Over 90 days, the company sees increased website traffic from target accounts, higher email open rates from sales sequences to those accounts, and improved conversion rates on LinkedIn ads targeting the same audience.
That’s the connection between media spend and pipeline that B2B has been missing from television advertising.
Premium Inventory: Why It Matters for B2B
Not all CTV inventory is equal, and for B2B, the distinction matters more than it does for consumer brands.
Premium inventory means Hulu, Disney+, ESPN, Peacock, and similar networks. Content produced by major studios and networks. Professional production quality. Brand-safe environments.
Long-tail inventory means smaller streaming apps, FAST channels with niche content, and open exchange inventory where you may not know exactly where your ad appeared. CPMs are lower, but the environment is less controlled.
For B2B brands, the content environment your ad appears in affects perception. A CTO watching your ad during a Hulu original series has a different brand association than seeing it on an obscure free app during reruns. When you’re spending to build credibility with senior decision-makers, the context matters.
That doesn’t mean every impression needs to be on Hulu. A practical B2B CTV allocation puts the majority of budget on premium networks for brand credibility, with selective use of other inventory for reach extension when the data supports it.
Measuring CTV for B2B
Consumer CTV measurement focuses on reach, frequency, and video completion rate. B2B needs more than that.
Metrics that matter for B2B
- Account reach: How many of your target accounts were exposed to your ads? Not impressions. Accounts.
- Account frequency: How many times did each account’s household see your ads? Frequency matters for awareness, but too much wastes budget.
- Website activity from target accounts: After your CTV campaign runs, are you seeing increased visits from the companies on your target list? This is one of the strongest signals CTV is working.
- Pipeline influence: For accounts exposed to CTV, how do their deal progression rates compare to unexposed accounts? This requires connecting your CTV data to your sales data.
- Brand lift: Survey-based measurement of awareness, consideration, and intent among exposed vs. unexposed audiences.
- Cross-channel impact: Are your search, social, and display campaigns performing better while CTV is running? Look at conversion rate changes, not just volume changes.
Incrementality testing
The most rigorous way to measure CTV’s impact is a geo-lift test. Pick two similar markets. Run CTV in one, not the other. Measure the difference in pipeline metrics across both. This controls for all the other marketing activity happening at the same time and isolates CTV’s contribution.
Give any CTV test at least 90 days. B2B sales cycles are long. If you pull the plug after 30 days because you don’t see direct conversions, you’re measuring the wrong thing on the wrong timeline.
Getting Started with B2B CTV
If you’re new to CTV, here’s a practical path:
1. Define your audience
You don’t need an account list to start. If you have one, great: upload your top 500-1,000 accounts and target the companies you actually want to reach. Prioritize accounts with active opportunities, high-intent signals, or strategic importance.
If you don’t have a named account list yet, you can build your audience using firmographic and job title targeting. Define your audience by company size, revenue, industry, and job title, the same way you would on LinkedIn, but delivered as TV spots on premium streaming. Either path gets you to the right decision-makers.
2. Get your creative ready
You need video. A 30-second spot is the standard CTV unit. If you have existing brand video from events, social campaigns, or corporate content, it may be adaptable. The production quality needs to hold up on a 55-inch screen, but you don’t need a Super Bowl budget. Authentic storytelling beats over-produced corporate messaging.
3. Set expectations with leadership
CTV is an upper-funnel, brand-building channel for B2B. It drives awareness, website visits, and improved performance across other channels. It does not drive immediate form fills. Align your leadership on the right KPIs before you launch so you’re measuring success correctly.
4. Run for at least 90 days
B2B buying cycles are long. A 30-day CTV test will show you delivery metrics (impressions, completion rates), but it won’t show you the downstream pipeline impact that makes CTV valuable. Commit to 90 days minimum.
Frequently Asked Questions About CTV Advertising
What is CTV advertising?
CTV (Connected TV) advertising is the delivery of video ads to internet-connected television devices like smart TVs, Roku, Amazon Fire TV, and Apple TV. Ads run within streaming content on platforms like Hulu, Disney+, and Peacock, and are bought programmatically with digital targeting and measurement. Unlike traditional TV, every CTV impression is trackable.
How is CTV advertising different from traditional TV?
Traditional TV ads are bought by daypart and program with estimated audience sizes from Nielsen. CTV ads are bought programmatically with precise targeting (down to the household level), real-time delivery confirmation, and measurable outcomes. CTV also supports account-based targeting for B2B, something traditional TV cannot do.
Can B2B companies use CTV advertising?
Yes. B2B brands are increasingly moving budget into CTV. The key is using account-based targeting rather than demographic targeting. Upload your target account list, match those companies to employee households, and serve ads on premium streaming networks to reach decision-makers where they watch TV.
What is Account-Based Television?
Account-Based Television is a CTV advertising approach built for B2B. Instead of targeting by demographics or behavioral segments, it starts with your target account list and matches those companies to the households of their employees. Ads are served on premium streaming inventory, and results are measured at the account level: which accounts were reached, how often, and what happened downstream.
How much does CTV advertising cost?
CTV advertising costs vary based on targeting specificity, inventory quality, and seasonality. B2B campaigns with account-based targeting may index higher on CPM but deliver significantly more relevant impressions than broad demographic targeting. The best way to understand pricing for your account universe is to talk to a platform that specializes in B2B CTV.
How do you measure CTV advertising for B2B?
B2B CTV measurement goes beyond standard reach and frequency. Key metrics include: account reach (how many target accounts were exposed), website activity from target accounts after ad exposure, pipeline influence (how exposed accounts progress vs. unexposed), brand lift surveys, and cross-channel performance improvements in search, social, and display.
What is the difference between CTV and OTT?
CTV (Connected TV) refers to the device: a TV connected to the internet that can stream content. OTT (Over-the-Top) refers to the delivery method: content delivered over the internet, bypassing cable. OTT includes streaming on phones, tablets, and desktops. CTV is specifically OTT content viewed on a television screen.
What CTV completion rates can B2B advertisers expect?
CTV ads have the highest completion rates of any digital video format. 30-second CTV ads complete at roughly 96%, compared to 74-83% for desktop video, 69-75% for mobile video, and 10-30% for social video. The lean-back, non-skippable viewing environment drives this performance.
