Introduction: Uncover the Real Impact of Every Marketing Investment
CMOs, in a world where every dollar counts, how do you know if your marketing campaigns are generating a real impact and not just “cannibalizing” results you would have achieved anyway? The answer lies in incrementality. This powerful metric allows you to go beyond correlation to understand causality – that is, what part of your results is directly attributable to your marketing efforts, and not to external factors or organic demand. This post will guide you on what incrementality is, why it’s vital for your marketing models, and how you can use it to test new channels with confidence. Get ready to unlock the true potential of your budget.
The CMO’s Dilemma: Spending or Investing Wisely?
The big challenge for CMOs today is how to test and use incrementality to effectively test new channels. It’s easy to fall into the trap of only optimizing what’s easy to measure (like last-click), but this doesn’t always reveal the incremental impact of a campaign. The problem isn’t just spending, but spending intelligently. You need to know if your additional investment in a channel is truly bringing in new customers or sales, or if you’re simply paying for conversions that would have happened anyway. Incrementality solves this dilemma, offering a clear view of the added value of each action.
What is Incrementality and Why Is It Your Best Ally?
Incrementality measures the difference in consumer behavior (e.g., conversions, sales) between a group exposed to a marketing action and an unexposed control group. It’s not just about attribution, which assigns value to each touchpoint; incrementality validates whether that touchpoint generated the result, or if it was merely a bystander.
Think of incrementality as the true thermometer of ROI. It’s crucial for several reasons:
- Avoid wasted spend: It helps you identify where you’re over-investing without getting incremental results.
- Optimize budget allocation: It allows you to reallocate funds to the channels and campaigns that truly drive growth.
- Validate new channels: It offers a robust framework for testing the effectiveness of new platforms or strategies before scaling investment.
How to Measure Incrementality: The Tests You Need
To measure incrementality, controlled experiments are often used. These are some of the most common methods:
1. Geo A/B Tests (Geo-experiments):
- How it works: You divide your geographical markets into “treatment” groups (where the campaign or new channel is launched) and “control” groups (where it’s not launched). You compare performance between both groups to isolate the incremental impact.
- When to use it: Ideal for testing the incrementality of high-impact channels (TV, OOH) or for evaluating the potential of new markets. It requires good geographical segmentation and sufficient scale.
2. Holdout Group Tests:
- How it works: Within your target audience, you hold out a small percentage that won’t be exposed to the campaign or the new channel. Then, you compare their behavior with that of the exposed group.
- When to use it: Excellent for measuring the incrementality of digital campaigns (display, social media, email marketing) where it’s easier to create control groups at the user level. It’s a practical way to understand the incrementality of your actions.
3. Econometric Models (MMM with Incremental Component):
- How it works: Advanced Marketing Mix Modeling (MMM) can incorporate incrementality analysis by quantifying the incremental impact of each channel over time, beyond baseline demand.
- When to use it: For a holistic and strategic view, when you seek to understand the incremental impact of all channels and their interactions in the long term.
Incrementality: Your Compass for Testing New Channels
Incrementality is not just a metric; it’s a mindset. It allows you to approach the exploration of new channels on a scientific basis. Instead of making a large investment and crossing your fingers, you can design an experiment, measure the incremental impact, and make data-driven decisions about whether a new channel truly adds additional value. This reduces risk and ensures your resources are optimally allocated. The key is to be methodical and have the right tools to implement and analyze these incrementality tests.
Conclusion: Unlock True Potential with Incrementality
In modern marketing, moving from superficial attribution to incrementality analysis is a quantum leap towards true ROI optimization. It allows CMOs not only to understand what works, but how much more it works thanks to their investment. By mastering the techniques to measure incrementality and applying them to test and validate new channels, you can ensure that every dollar of your marketing budget generates significant incremental impact.
