I’ve spent my entire career working in programmatic media and CTV, and let me tell you: click-based attribution has always been a shaky foundation to build serious marketing decisions on.
Easy to report? Sure. Accurate? Not remotely.
That’s why Microsoft’s announcement introducing impressions-based remarketing caught my attention. Not because I think Microsoft will flip the industry on its head (they just don’t have the scale) but because it signals a broader, long-overdue shift in how we evaluate media that will pay dividends in the long term.
For B2B marketers specifically, this shift matters more than most people realize. Click-based attribution has been quietly distorting your media mix for years, overvaluing bottom-funnel channels and starving the ones that actually build pipeline. Here’s why that’s changing and what to do about it.
Clicks Were Never Enough
In programmatic and CTV, we’ve never had the luxury of clicks as a clean proxy for performance. A 30-second CTV spot doesn’t come with a “click here to buy now” button. A banner ad campaign usually draws few clicks but many thousands of harder-to-value impressions.
To argue convincingly for our channels, we’ve had to build more sophisticated muscles: incrementality testing, media mix modeling, and lift studies.
That’s the only way to answer the real questions marketers should be asking:
- Did this channel actually move the needle?
- Would the conversion have happened without the exposure?
- How much credit should upper-funnel impressions get for downstream results?
Click-based reporting makes those questions a nice-to-have that usually gets deprioritized. Impressions-based frameworks make them unavoidable.
The B2B Attribution Problem
This is where it gets specific to B2B. In a click-based world, your attribution report looks something like this:
- A decision-maker sees your CTV ad on Tuesday night. No click (there’s no mouse on a TV).
- Wednesday, they see your LinkedIn ad in their feed. No click (they’re scrolling).
- Thursday, a colleague forwards them your blog post. They read it. No click tracked.
- Friday, they Google your company name. Click. Visit your site.
- The following week, your SDR reaches out. They take the meeting.
- Two months later, the deal closes.
In a last-click model, Google search gets 100% of the credit. In a multi-touch model, maybe LinkedIn and the blog post get partial credit. CTV gets nothing. The Tuesday night impression that started the entire chain is invisible.
This isn’t a theoretical problem. It’s happening in your attribution dashboard right now. Every B2B company running CTV alongside search, social, and display is systematically undervaluing the channel that built the awareness while overvaluing the channels that captured the demand.
What Happens When Impressions Become the Currency
When you take away the crutch of last-click attribution, the spotlight shifts. Suddenly, retargeting, brand search, and other bottom-funnel tactics don’t look nearly as magical. MMM and lift tests measure those channels in the full marketing picture, which tends to diminish the perceived value they carry in last-click measurement systems.
Meanwhile, channels like CTV, programmatic display, and upper-funnel social start to get their due. These are environments where ads are far more likely to be seen, and their impact echoes downstream in ways a click will never capture.
For B2B, the rebalancing is even more dramatic:
LinkedIn’s dominance gets questioned
LinkedIn is the default B2B channel because it clicks well and converts measurably. But when you run incrementality tests, you often discover that a significant portion of LinkedIn conversions would have happened anyway. The people clicking your LinkedIn ads are already in your funnel. They were going to convert through some path.
CTV reaches people who aren’t in your funnel yet. It builds the awareness that makes every other channel work better. In an impressions-based framework, that contribution becomes visible for the first time.
This doesn’t mean you stop running LinkedIn. It means you stop giving it 100% of the credit for conversions that CTV, content, and brand presence helped create.
Upper-funnel investment gets justified
Every B2B CMO has had the conversation: “Why should we spend on brand when we can’t prove it drives revenue?” Click-based attribution makes that a hard argument to win because brand channels don’t produce clicks.
Impressions-based measurement changes the math. When you can show that branded search volume increased 30% during CTV flights, that LinkedIn conversion rates improved while CTV was running, and that target accounts visited your website at higher rates after ad exposure, the brand investment case builds itself.
Media mix decisions improve
Most B2B media mixes are bottom-heavy. 60-70% of budget goes to demand capture (search, retargeting, LinkedIn) because those channels show measurable results. 10-20% goes to awareness because it’s “hard to prove.”
That allocation is a product of the measurement system, not reality. When you measure impressions and their downstream effects properly, you often find that awareness spending (including CTV) is the most efficient dollar in the mix. It’s what makes the demand capture channels work.
Why CTV Stands to Gain the Most
I’m biased, but for good reason: CTV has always been an impressions-first channel. Every ad is full-screen, non-skippable, and fully delivered. Completion rates aren’t just high; they’re essentially 100%. In an impressions-driven world, that kind of inventory stands out as both efficient and high-value.
When you layer in account-based targeting, the value compounds. You’re not just delivering quality impressions to a broad audience. You’re delivering them to the specific accounts in your pipeline, on the biggest screen in the house, in an environment where the ad gets watched start to finish.
No other B2B channel can make that claim. LinkedIn has targeting precision but low attention (thumb-scrolling past an ad). Display has scale but even lower attention (30% of viewable ads are actually looked at, according to Lumen Research). Search captures intent but doesn’t build awareness. CTV does something none of them can: it creates the awareness that feeds all the other channels.
In an impressions-based measurement world, that contribution finally gets recognized.
How to Make the Shift in a B2B Organization
Most experienced marketers know that there is no perfect measurement model. You won’t wake up tomorrow, swap clicks for impressions, and suddenly have a single source of truth. But if you test incrementality, run MMM, and mix in multi-touch attribution where it makes sense, you’ll get closer to reality than any click report ever gave you.
Here’s a practical path for B2B teams:
Step 1: Run a holdout test
The simplest way to prove impression-based value. Run CTV in some markets, hold out others, and compare pipeline outcomes. If the CTV markets show higher branded search, more website visits from target accounts, and better pipeline velocity, you have your proof. For the full methodology, see our CTV measurement guide.
Step 2: Track cross-channel lift
During CTV flights, monitor what happens to your other channels. If LinkedIn conversion rates improve, paid search CPAs drop, and sales outreach response rates increase, that’s CTV working. Document these improvements so you can attribute them correctly.
Step 3: Reframe the conversation with leadership
This is the hard part. Most executive dashboards are built around clicks and last-touch attribution. Changing the narrative requires showing leadership why the old model is misleading, not just introducing a new one.
The framing that works: “Our current reporting gives 100% of credit to the channels that capture demand. It gives 0% to the channels that create demand. We’re now measuring both, and here’s what we’re finding.”
Come with data from your holdout test. Show the branded search lift, the cross-channel improvements, the pipeline velocity difference. “Imperfect but closer to truth” beats “digestible but misguided” every time.
Step 4: Reallocate gradually
Don’t slash your LinkedIn budget overnight. Shift 15-20% of your demand capture spend toward CTV over a quarter. Measure the impact. If total pipeline stays flat or improves while you’ve diversified your channel mix, you’ve built a more resilient program that doesn’t depend on a single channel.
The Real Risk
The real risk isn’t in moving toward impressions-based measurement. It’s staying stuck in a click-based model that everyone knows is flawed and giving your competitors a head start to get smarter about where their dollars actually work.
B2B companies that figure out impression-based measurement first will build better media mixes, justify smarter investments, and ultimately generate more pipeline from the same budget. The ones that keep optimizing for clicks will keep overspending on demand capture and wondering why pipeline isn’t growing.
The shift is already happening. The question is whether you lead it or follow it.
Frequently Asked Questions About Impression-Based Marketing
What is impression-based marketing?
Impression-based marketing evaluates advertising based on whether the ad was seen (impressions) rather than whether someone clicked on it. This approach recognizes that many high-value channels (CTV, brand advertising, upper-funnel programmatic) influence purchase decisions without generating clicks. It's particularly relevant for B2B, where buying decisions involve multiple touchpoints over months.
Why is click-based attribution a problem for B2B?
B2B buying involves long sales cycles and buying committees. A decision-maker might see your CTV ad Tuesday, your LinkedIn ad Wednesday, and Google your company Friday. Click-based attribution gives all credit to the Google search and none to the CTV ad that started the chain. This systematically undervalues awareness channels and overvalues demand capture channels.
What is impression-based targeting?
Impression-based targeting focuses on delivering ads to the right audience in environments where the ad will be seen and remembered, rather than optimizing for clicks. In B2B CTV, this means targeting decision-makers at specific accounts on premium streaming networks where ads are full-screen, non-skippable, and fully completed. The targeting is based on who should see the impression, not who is likely to click.
How do you measure impression-based marketing?
Through incrementality testing (geo-holdout tests comparing markets with and without CTV), cross-channel lift analysis (monitoring branded search, LinkedIn conversion rates, and sales outreach response rates during CTV flights), and media mix modeling (MMM). These methods measure the downstream impact of impressions across your full program rather than tracking clicks in isolation.
How does impression-based measurement change B2B media mix decisions?
Most B2B media mixes over-invest in demand capture (search, retargeting, LinkedIn) because those channels show click-based results. Impression-based measurement often reveals that awareness spending (including CTV) is the most efficient dollar in the mix because it makes demand capture channels perform better. Teams that measure this way typically shift 15-20% of budget from bottom-funnel to upper-funnel channels.
Why does CTV benefit most from impression-based measurement?
CTV ads are full-screen, non-skippable, and complete at 95%+ rates. In a measurement system that values impressions and their downstream effects (rather than clicks), CTV's high-attention inventory becomes one of the most valuable buys in the media mix. With account-based targeting, those impressions reach the specific decision-makers in your pipeline.
Should I stop using click-based metrics entirely?
No. Click-based metrics still have a role in evaluating bottom-funnel channels like paid search and retargeting. The shift is about not using clicks as the only way to evaluate your entire media mix. Use clicks where they're meaningful (search, retargeting) and impression-based measurement where clicks don't exist (CTV, brand, upper-funnel).
