What B2B researchers are missing

Editor’s note: Nicole Stathopoulou is a senior vice president at Toluna in New York, with 15+ years of experience in marketing strategy and campaign and media effectiveness. She holds an M.B.A. from the Kellogg School of Management, an M.A. in cognitive science from Columbia University and a B.S. in computer engineering from the University of Patras. 

For decades, media planning has revolved around three familiar currencies: Impressions, reach and frequency. They are clean, tradable and operationally convenient. They map neatly to inventory, pricing and guarantees. 

And yet, they may also be quietly undermining campaign effectiveness.

When the objective is awareness, planners push for maximum reach, distributing impressions as broadly as possible. When conversion is the goal, frequency increases, reinforcing messaging among those already exposed. Often, a balance is struck using an one-size fits all planning heuristics like the effective frequency rule of more than three exposures within a channel.

But here’s the uncomfortable truth: Reach and frequency only tell us how many saw and how often. They don’t tell us what worked.

Even more critically, these metrics treat each channel in isolation, ignoring how real people experience campaigns  as connected multi-touch journeys across platforms, formats and environments.

And that’s where the inefficiency begins.

Because when we shift the lens from delivery metrics to incremental brand lift, a very different story emerges  one that challenges long-standing planning dogma and reveals hidden inefficiencies inside even the most well-optimized media plans.

What happens when you measure incrementality  not just delivery 

Across hundreds of cross-media effectiveness studies, we analyzed campaigns using a control–exposed design to establish true causal lift. We then applied media attribution modeling to isolate and quantify the incremental contribution generated at different levels of media exposure.  

We wanted to understand:

  • What happens when audiences see the advertising through one channel only? 
  • What happens when they see it through two channels?
  • What happens when they see it through three or more channels? 

Three patterns that challenge a brand’s traditional media planning 

The charts accompanying this article reflect real campaign data and illustrate patterns we consistently observe across brands, categories and objectives.

The top section below shows brand lifts delivered by the full campaign, representing the impact of the full media mix.

The bottom section deconstructs each lift, isolating the contribution generated by single-channel exposure, two-channel exposure and three-or-more-channel exposure, with the reach at each level shown for context.


The results are striking.

Campaign impact doesn’t grow linearly.  

Incrementality tends to plateau when optimizing within single channels.

More impressions in the same environment do not proportionally increase brand outcomes.

Returns diminish.

The sharpest lift occurs when three or more channels work together.

For upper- and mid-funnel KPIs awareness, message association, brand perceptions, preference, etc.  the real acceleration happens when audiences are exposed to three or more media channels.

This is where reinforcement turns into resonance.

Projecting the brand narrative across multiple channels creates a cognitive and emotional echo that strengthens memory encoding, deepens persuasion and amplifies impact.

A small share of the campaign’s reach drives most of the lift. 

In the representative example shown above, only 13% of total reach got to audiences that saw the advertising through three or more channels.

Yet, that small portion of campaign reach accounted for:

  • 100% of the lift in consideration.
  • 91% of the lift in emotional resonance.
  • 52% of the lift in campaign message association.  

In other words, a relatively small portion of total reach generated the majority of brand impact.

Meanwhile, the larger portion of campaign reach  those exposed through only one or two channels  contributed little meaningful incrementality.

The hidden inefficiency of “maximize reach” 

When we examined sub-audiences based on number of channels exposed, the pattern remained consistent  meaningful lift emerged only when at least three channels worked together. Exposure through one or even two channels delivered limited incremental value. 



Traditional planning dogma says that if the objective is brand building, boost reach.

So, budgets get stretched thin to broaden exposure. On paper, the campaign looks expansive. But, in reality, many consumers experience the ad in just one or two environments. And those lower cross-channel exposure levels tend to be largely ineffective.

The result? A significant share of campaign impressions generates little real value.

This isn’t a media cost issue. It’s an allocation issue.

Channel frequency vs. synergy: A critical distinction 

We also examined another core assumption: Is increasing frequency within a single channel equivalent to cross-channel reinforcement?

The data says no. 


When comparing single-channel exposures delivered at high frequency versus cross-channel exposures where each channel in the mix runs at low frequency.

In other words, reinforcing a message across channels amplifies impact more effectively than repeating it within one channel.

Advertising that reaches people from multiple directions deepens engagement, strengthens memory and boosts impact, while minimizing ad fatigue. It creates reinforcement, not just repetition.

From volume to value: Rethinking media effectiveness

Campaign budgets are never infinite. Every plan operates within a fixed pool of impressions.

The real question is not: How do we maximize reach?

The real question is: How to deploy those impressions most effectively to maximize returns?

Our findings suggest that maximizing reach without enabling coordinated exposure can be suboptimal. Impressions that drive single-channel and two-channel exposures tend to underperform. The strongest gains come from multi-platform integrated exposure patterns that reinforce one another and create impact greater than the sum of their parts.

Yes, that may mean sacrificing some reach  the ineffective portion.

But the trade-off is clear  fewer wasted impressions, stronger incremental returns.

It’s time to evolve the planning currency 

Media planning needs to shift:

  • From impressions to incrementality.
  • From channel silos to cross-channel orchestration.
  • From volume metrics to value creation. 

Advertising isn’t experienced in silos. And it shouldn’t be planned that way either.

The future of media planning and execution isn’t about reaching more people. It’s about ensuring impressions work harder and create coordinated multi-touch exposure that augments impact.

That’s the real growth engine hiding inside today’s media plans.
