What we found
- In weeks with heavy LinkedIn CTV and streaming audio investment, leads more than doubled and sales-qualified leads nearly tripled against light-spend weeks — measured three weeks downstream, across 50+ weeks of data
- The response to CTV and streaming audio exposure lands three to eight weeks after the impression. That lag is why last-click attribution reports these channels as dead weight.
- When the same client paused all streaming and social spend for a quarter, sales-qualified leads fell by close to 90% year over year, while paid-search-fed demand held up better.
The last B2B channel most businesses consider
If you're a B2B startup trying to grow pipeline, LinkedIn CTV ads are probably not on your list. We talk a lot about cost per lead, lead volume, pipeline, sales follow-ups via email, and AI-powered sales automation platforms. And we get it — there's a lot of really cool B2B marketing tech out there. But it's been a minute since anyone talked about how CTV and streaming audio can impact your bottom line.
We worked with a client running a familiar playbook: heavy linear TV and local radio, alongside some CTV and streaming audio. The TV and radio spend was solid, but the performance was inconclusive. As usual with linear, everyone says it's working and nobody can prove it — and when your buyers are a narrow professional audience, working means a lot of people are seeing the ads who will never become customers.
What we did instead
We took the TV and radio dollars and moved them into a more unusual play for a business selling into a professional niche: LinkedIn CTV, plus targeted streaming audio.
LinkedIn CTV is unusual in that your ads run on the big screen while your targeting stays LinkedIn's — job title, company, industry, seniority, function, even customer lists. LinkedIn matches your targeted users across streaming TV. CPMs run higher than broader-reach channels, but LinkedIn's professional audience data makes it one of the strongest options for reaching highly specific B2B audiences on CTV.[1]
How we measured it without the jargon
We evaluated every week of the year around one central question: did heavier investment in LinkedIn CTV and streaming audio correlate with increased acquisition pipeline growth several weeks later?
Very few people see a streaming ad and immediately fill out an enquiry form.
The "several weeks later" part matters. Streaming TV and social advertising tend to operate with a delayed-response effect. Audiences may not act immediately after exposure, but increased brand recall and consideration can drive branded search and site visits weeks later.[2] That delayed effect is the thing we wanted to capture.
The response shows up weeks after the impression
Why a last-click report reads these channels as dead weight.
So we sorted all 52 weeks into a heavy-spend group and a light-spend group, and compared what happened to the funnel about three weeks downstream of each. Same client, same year — just different spend levels week to week.
What we discovered
Heavy-spend weeks vs. light-spend weeks
The strongest movement showed up exactly where the targeting was pointed. LinkedIn CTV was aimed at a specific professional audience, using professional targeting layered on premium streaming inventory, and that's the segment that moved hardest. Traffic from audiences the targeting wasn't built to reach moved too, but far less — which is what you'd want to see. If everything had lifted equally, we'd be looking at a seasonal effect rather than a channel effect.
High-spend LinkedIn weeks more than doubled pipeline output
Top-tertile vs. bottom-tertile LinkedIn-adstock weeks, measured three weeks downstream.
Then the client paused it
The client paused the entire streaming and social mix for a quarter. LinkedIn CTV, LinkedIn feed, and the streaming video and audio platforms all went dark. They kept a small paid search budget running. That was it.
After a long search for a clean test, the conditions arrived on their own.
Still, correlation isn't causation
Strong numbers, but a solid skeptic could still push back: sure, but maybe the heavy-spend months had other things going on, too. Niche B2B always has that problem — small absolute volume, long sales cycles, lots of moving parts that could be confounders.
Which is why what happened next was useful.
What was left after the mix went dark
Same quarter, one year later. 1.0× would mean flat.
Outline shows the prior year at 1.0×. Fill shows what remained.
In other words: the audience the mix was specifically built to hit is the audience that fell hardest when it disappeared. The relative magnitudes line up exactly the way you'd expect.
The pattern underneath is intuitive once you break the data apart. Paid search kept running at a lower level, so the part of the funnel it fed held up better. But the professional audience had no equivalent backstop — LinkedIn CTV and LinkedIn feed were the only channels targeting them directly, and both went dark at once.
Why this matters for B2B
What to take from this
- LinkedIn CTV and streaming audio aren't soft brand spend you can pause when budget gets tight.
- For a niche B2B audience, they feed the branded search and direct traffic that last-click credits to Google Brand.
- Pause them and you lose the pipeline they would have generated three to eight weeks later.
For a niche B2B audience, they're the channels feeding the branded search and direct traffic that last-click happily credits to Google Brand or your contact form. Pause them and you don't just lose the impressions — you lose the pipeline they would have generated three to eight weeks later.
We understand why many B2B marketers still overlook these channels. For years, CTV and streaming audio were treated as B2C tactics. With LinkedIn's professional targeting sitting on top of premium streaming inventory, that isn't true anymore.[3] The teams who work this out get to show up on the same screens and audio platforms their buyers actually use, with a level of audience precision broadcast can't touch.
So if your CTV, streaming audio, or paid social budget "isn't converting" in last-click, the cheapest way to find out whether that's true is to pause it for six weeks and watch what happens to the leads in your CRM.
You may be surprised by what you find.
Common questions about LinkedIn CTV
Does LinkedIn CTV work for B2B?
In this engagement it did, measurably. Weeks with heavy LinkedIn CTV and streaming audio investment more than doubled leads and nearly tripled sales-qualified leads against light-spend weeks, measured three weeks downstream. The caveat worth stating: this is one client over one year, and the effect is correlational rather than a randomised test — though the client's later spend pause functioned as an unplanned control.
How long does LinkedIn CTV take to show results?
Three to eight weeks between exposure and the downstream response. Streaming builds recall before it builds intent, so the branded search and demo requests arrive well after the impression that caused them. Any test shorter than about six weeks will read as a failure regardless of whether the channel is working.
Why doesn't LinkedIn CTV show up in attribution reports?
Because there is no click. Someone sees a fifteen-second spot on their television, and weeks later searches your brand name or types the URL directly. Last-click credits that conversion to Google Brand or direct traffic. The CTV impression that started it appears nowhere in the path, so the channel looks like pure cost.
How do you measure LinkedIn CTV without a clean control group?
Sort every week of the year by spend level, then compare downstream funnel output between the heavy and light groups at the appropriate lag. It holds client, product and audience constant while spend varies naturally week to week. It is not a randomised experiment, but it is far better than a last-click report and it uses data you already have.
What makes LinkedIn CTV different from regular CTV advertising?
The targeting. Standard CTV buys against demographics and content. LinkedIn CTV runs on premium streaming inventory but targets on LinkedIn's professional graph — job title, company, industry, seniority, function, and uploaded customer lists. That is what makes a big-screen channel viable for a niche B2B audience instead of mostly wasted reach.
Can you pause LinkedIn CTV to save budget?
You can, but expect the cost to land a month or two later rather than immediately. When this client switched off streaming and social for a quarter, sales-qualified leads dropped by close to 90% year over year. The audience the mix was built to reach fell hardest, because nothing else was targeting them directly.
