Understanding Incrementality Measurement in Modern Marketing
The modern data-driven marketing environment no longer comes down to how many people you reach or how much budget you spend. It is a matter of knowing what really works, and what does not. In comes the concept of incrementality measurement, which can truly become one of the most useful tools of marketers who hope to make wiser and more effective decisions.
Measuring incrementality is not just a superficial measure e.g. clicks or impressions. It attempts to address a more important question: What would have been the case had we not conducted this marketing campaign? That is, it gauges what a marketing activity actually contributes, and not what would have happened automatically.
If you ever asked yourself “what is incrementality measurement” here’s what you need to know:
What Is Incrementality Measurement?

Incrementality measurement is a method that is applied to measure the causal effect of a marketing campaign or tactic. It provides an answer to one of the fundamental business questions: Did our campaign really affect customer behavior, or would these conversions have occurred anyway?
Last-click attribution, impressions, or even conversions are traditional metrics that can be misleading often. The fact that a client has seen an advertisement or clicked on it does not imply that advertisement led to the sale. Incrementality aims to identify and quantify the net change or behavioral change, which can be solely attributed to the campaign.
An example of this is that when 100 people convert after viewing a display ad, 70 of which would have converted regardless of the display ad, the incremental effect is only 30 ad conversions. This is essential in the comprehension of the return of ad spend (ROAS) and more effective budgeting. Discover more on this page.
How it Works?
In order to quantify incrementality, controlled studies are usually set up, using methods like A/B testing or holdout groups. Typically, it goes like this:
Group A (the test group) is exposed to the campaign.
Group B (the control or holdout group) is not.
Marketers may find out how much of an uptick the campaign actually produced by comparing the two sets of data, particularly with regard to conversions, purchases, and signups.
Channel efficacy (e.g., retargeting or sponsored search) might be skewed due to biases like self-selection or correlation; this sort of testing helps remove these issues.
More complex approaches include synthetic control models, geo-testing, and multi-touch attribution models with incrementality weighting. Learn more here https://digiday.com/marketing/roas-vs-incrementality-scrutiny-around-ad-spend-grows-in-booming-retail-media-space/.
The Main Advantages of Incrementality Measurement
More Efficient Use of Funds
Finding the best place to invest your money is one of the main benefits of measuring incrementality. Marketers may find out which efforts are making a difference, rather than wasting money on several channels that don’t deliver much lift.
It may still be worthwhile, albeit maybe not on the same scale, to pursue a channel or campaign that has modest incremental value. Conversely, it is easier to scale up initiatives with a high rate of incremental improvement. Because of this, marketing spending may be fine-tuned for efficacy rather than merely activity.
Removes the Possibility of Unfounded Claims
Because they come last in the consumer journey, attribution models tend to give too much credit to specific channels. False positives, in which efforts look effective in theory but fail to inspire action, result from this.
That background noise is removed by incrementality. It shows which actions are really caused by marketing and which would have happened anyhow by evaluating what occurs when a user doesn’t see the ad.
This is particularly crucial for influencer marketing, sponsored search, and retargeting, as conversions frequently occur independently of ad exposure.
Boosts Strategy Across Channels
By measuring incrementality, you can find out which channels work and how they complement one another. Although some channels may not be very effective when used alone, they can greatly enhance the effectiveness of other tactics when combined.
A more unified and effective cross-channel strategy is the result of an understanding of these relationships. You’ll have a good grasp on when to use awareness as a lead, when to use retargeting, and how to combine channels for maximum funnel efficiency.
Boosts Return on Investment and Marketing Efficiency
Maximizing efficiency is the essence of incrementality. When you know what drives success, you can put your energy where it will do the most good. Less waste, increased focus, and a stronger return on investment are the results.
You base your marketing decisions on causality and evidence rather than assumptions or vanity metrics. With every dollar having to work in today’s competitive landscape, having that type of clarity is a huge plus.
Promotes Invention and Testing
In a test-and-learn setting, incrementality measurements are taken. Experimentation, creativity, and continual optimization are fostered by this.
Need to test out a different ad network? To determine its true effect, conduct an incrementality test. Does the efficacy of your loyalty program’s email marketing surprise you? See how they stack up against a baseline group.
This methodical strategy encourages inquisitiveness and constant development while simultaneously enhancing performance.
