In today’s fragmented media landscape, marketers are expected to do the impossible: plan campaigns that span multiple channels, deliver consistent results, and maximize every dollar, without ever knowing for sure what the outcome will be.
It’s not a simple thing to do either. When you consider the various audience segments you have to target, the different advertising channels you need to use, and the strategies you need to implement, forecasting can be rather a daunting challenge.
This is the marketer’s dilemma.
The Problem with Traditional Forecasting
For years, forecasting tools have promised clarity. But the reality? Many fall short when it comes to the complexities of modern media planning.
Traditional tools often provide broad, aggregated estimates that might work when you’re running a single-channel campaign. But what happens when you need to forecast across tactics, channels, and audience segments simultaneously?
You’re left juggling spreadsheets, back-of-the-envelope math, and a lot of guesswork. Marketers think that traditional forecasting can be used as an ultimate, one-size-fits-all type of solution to an otherwise multi-faceted, multi-layered problem.
Not only that, traditional forecasting tools are also typically treated as some sort of “crystal ball”, something that can help you predict the future outcome. However, that is not entirely accurate. You make decisions based on guesswork, run campaigns blindly without any predictive insights, and waste your budget and resources. Ultimately, it results in having no visibility into potential reach or impact.
Why Multi-Strategy Forecasting Matters
As marketing strategies become more sophisticated, so too should the tools we use to plan them. Marketers today are expected to layer omnichannel campaigns – including display, video, audio, native, and digital out-of-home – build a cohesive message across all of them, target different audience segments, and stay agile as user behaviors and expectations shift in real time. But that’s not all.
In reality, when planning a campaign, we’re also expected to navigate multiple strategies across each channel simultaneously, which sometimes involves handling separate costs, budgets, and targeting parameters – including audience segments – for each channel.
From there, what we need for planning is the ability to test various strategies to identify the optimal route — how much to invest, what the costs will be, and which strategy is most likely to drive the most users, even before the campaign launches.
However, we often come across platforms that don’t adapt to this dilemma. In some, the forecasting is done per channel, and users face the daunting, tedious challenge of having to repeat the forecast for each one. In others, we can forecast all channels together, but with the unfortunate limitation of the same targeting being applied uniformly across all of them.
Without the ability to forecast at a granular level, you’re flying blind.
In today’s ever-evolving marketing landscape, being able to see which strategy will drive the most users, and how different CPMs impact reach isn’t a luxury—it’s a necessity.
What Marketers Really Need
Modern forecasting needs to go beyond the basics. Here’s what today’s marketers should be demanding:
- One unified forecast view – Not just a reach estimate per channel, but projections for each individual strategy within it.
- Smart scenario planning – The ability to adjust variables like budget, CPM, or audience targeting and see how each change impacts delivery.
- Granular targeting – Forecasting should reflect the real complexity of your plan, not force one-size-fits-all assumptions.
- Winnable audience clarity – See your campaign’s full potential and avoid inflated numbers that don’t reflect reality.
The Stakes are High
Misaligned forecasts lead to underdelivery, overspending, and missed KPIs. Worse, they erode trust internally with stakeholders and externally with clients.
More than ever, we need tools that can make us feel confident in making decisions from forecasts based on accurate data. We also need the means to help minimize the risk and uncertainty in our decision-making, and resources that can give us clear visibility to understand potential outcomes. Moreover, we need transparency – being able to see how variables impact results.
As marketing continues to evolve, the tools we use must evolve with it. Forecasting is no longer just a step in the planning process; it’s a strategic function that can make or break a campaign before it ever launches.
So, What’s the Solution?
It’s not enough to just have a forecasting platform that can give you half-baked assumptions. We need forecasting that empowers users to make data-driven media planning decisions by providing accurate projections of campaign impact.
It’s time to move from approximations to precision. We must go beyond channel-level guesses to tactic-level clarity. Because in a multi-strategy world, marketers need more than estimates—they need confidence.
