Connected TV keeps showing up in budget decks as a line item nobody can defend. A new piece on MarTech argues that B2B marketers heading into 2027 planning season have a narrow window to fix that — by running a small, deliberately unambitious CTV test that produces planning inputs rather than a verdict.
The logic is simple. Most B2B teams close their 2027 plans between now and Thanksgiving. If you walk into that meeting without your own CTV numbers, you either drop the line or defend a figure lifted from a vendor deck. And a number nobody can source is usually the first casualty when cuts start.
What 90 days can actually tell you
The argument draws a hard line between two very different claims: generating real data about CTV against your account list, and proving CTV works. A quarter is enough for the first, nowhere near enough for the second.
Within eight to 10 weeks of usable runway, the piece says a focused test can answer four questions:
- Reach against your list. A vendor’s addressable universe is not your reach. Most CTV platforms are built for B2C and only carve out B2B afterwards, so teams tend to overestimate how much of their target account list is actually reachable in streaming.
- Cost to deliver against your ICP. Broad CTV delivery is cheap and largely irrelevant. The number worth carrying into a planning meeting is what it costs to reach your actual buyers often enough to register.
- Whether your creative survives a TV screen. Most B2B video was cut for a scroll feed. On CTV it plays full-screen and unskippable to someone who chose to sit down. Plenty of teams discover in week three that their library does not hold up.
- Whether targeted accounts show up on your site. Website visit lift is described as the first honest — though directional — signal. If traffic from targeted accounts moves while untargeted accounts stay flat, something is happening well before pipeline could register it.
What it won’t buy you
Incrementality and payback are off the table. A defensible incrementality test needs account-level randomisation, a holdout suppressed across every line item rather than just the CTV campaign, and enough conversion volume to hit significance. In B2B, with long cycles and finite account lists, that takes far longer than a quarter. If a vendor claims 90 days settles incrementality, the advice is to push back.
There’s a useful CFO angle here for Indian marketers too. Rather than making claims, set expectations: this test is about reach, cost, creative viability and early site signal. Finance teams are generally more comfortable with an honest “here’s what we don’t know yet” than marketers assume. Hazy expectations are what get plans killed.
Buy narrow, because supply is getting messier
There’s a market reason to keep the test tight. Ad loads are climbing — Prime Video doubled its ad load after launching its ad business in early 2024, and eMarketer noted in February that other platforms are following. Lighter ad loads were part of what justified CTV’s premium pricing; as loads rise and supply grows, streaming CPMs are flattening. A cheap, wide buy today sweeps in a lot of media with nothing to do with your buyers.
Buyers can sense it. The IAB’s 2026 Digital Video Ad Spend & Strategy report projects CTV spend growing 11% this year, yet 43% of buyers expressed “somewhat to no confidence” in the quality of inventory they are buying. Targeting and audience reach now rank as equally important as business outcomes. IAB’s Chris Bruderle summed up the buyer’s question as where the ad actually ran, where the inventory came from, and how much of it is invalid traffic.
Keep the design boring
The recommended test design is deliberately unsophisticated: pick one account segment or market — ideally the tier sales is already working — concentrate delivery on a couple of premium apps or one trusted inventory source, set frequency high enough to reach a buying committee and leave it alone, and run one or two creative variants instead of a full matrix.
Sort out tracking before the first impression, agree upfront which accounts count as targeted, and put the readout on the calendar in the same week your planning numbers are due. A readout that lands late is a readout for next year’s argument.
And be prepared for a no. If reach is thin or ICP delivery costs more than the channel can return, leaving CTV out of the 2027 plan is a legitimate outcome — weak creative, by contrast, is a fixable problem, not a reason to skip the channel. The worst outcome is funding the line on faith.
