What Is Incrementality in Marketing?

Incrementality in marketing is the lift or increase in the desired outcome (for example, awareness, web visits, conversions, revenue, profitability) provided by marketing activity. 

Incrementality testing and measurement can provide the true incremental contribution of your paid media at the channel, tactic, campaign, or ad set level. Incrementality in marketing is especially needed for channels where ad impressions are difficult to map and measure, such as “walled garden” social channels including Facebook, Snap and Pinterest, or even TV and direct mail.

Why Is Incrementality Measurement Important?

Because they don’t have access to all the data outside their own environment, every digital ad platform uses the same flawed last-touch attribution method. Reports provided by ad platforms will never match up with site-side analytics reports or what’s observed in a brand’s sales data. Taking platform reporting at face value is a risky practice that can lead to bad decisions and lost revenue.   

which media investments contribute to business metrics and by how much. Measuring for incrementality identifies where to eliminate waste and surfaces opportunities to scale, expand and reallocate media spend for maximum growth. 

With incrementality measurement, you can answer questions like:

  • Which media channel, publisher, or campaign is contributing to my desired outcome (leads, LTV, ROAS, revenue, net profit/$, etc.)?
  • What happens if I start buying media from a new platform or if I reduce or stop buying ads with a platform?
  • Will launching new campaigns or ads increase contribution to conversions at the portfolio level or will it cannibalize from other channels?

How do you measure incrementality of media?

The most accurate way to measure incrementality of media is through testing and experimentation. To measure incrementality, audiences are randomly segmented into test and control groups. The difference in conversion rates between the two groups demonstrates the marginal incremental contribution of that media channel.

Incrementality measurement can vary in complexity from a simple holdout test as described above to multivariate experiments so elaborate they require the expertise of a trained data scientist. But, when carefully designed and cleanly executed, controlled experiments can utilize data from an unlimited number of sources to reveal the incremental impact of just about anything marketers want to test – on any outcome that can be measured.

Let’s look at some examples of incrementality in marketing and see how incrementality is calculated

Perhaps a brand wants to better understand the effectiveness of its retargeting campaign. To calculate the incrementality, they would withhold a small but statistically significant group of their audience (typically 10%) and not serve them the retargeting ads. Out of this group, which did not see the retargeting ads, 10% end up repurchasing the products.

The test group did receive the ads, and they repurchased 13% of the time. Using these numbers, we can use the incrementality formula to calculate incrementality.

The incrementality formula: (%CR Test – %CR Control) / %CR Test

So in our example, the incremental lift is 3%, which based on the formula, results in a 23% incrementality.

Incrementality Case Study: Soft Surroundings

Soft Surroundings, a women’s clothing retailer, chose to work with Measured to better understand and optimize their retargeting efforts.

Measured’s retargeting experiment revealed that the incremental cost per acquisition CPA(i) was well above CPA targets and what was reported by the vendors. The company’s largest retargeting vendor by spend was heavily over-indexed and serving ads beyond a recommended frequency cap.

As a result of these findings, retargeting budgets were reduced by 52% in the next few months. The extra budget was shifted to higher-performing prospecting tactics like Facebook. Topline revenue improved 17% MoM while yearly sales comps increased 12%.

The Impact of Incrementality Measurement in Marketing

Incrementality in marketing allows you to see which audiences should be served which ads and on what platforms. 

Other methods of measurement, such as media mix modeling (MMM) and multi-touch attribution (MTA), cannot measure views or impressions, so you’re essentially just measuring clicks. Incrementality measurement accounts for the impressions and clicks within each of the platforms under test to give marketers a more accurate view of the true contribution of their media across the entire portfolio.

Press    How Do You Calculate Incremental Sales Driven by a Media Tactic?

Original Publisher

The impact of a marketing tactic (eg: Facebook prospecting, retargeting, catalog, direct mail, national TV) is typically measured in terms of incremental sales driven by that tactic. Incremental sales driven by a media tactic are calculated using advanced marketing measurement techniques. There are three major types of advanced marketing measurement techniques.

  • Design of Experiments (DoE)
  • Marketing Mix Modeling (MMM)
  • Multi-Touch Attribution (MTA)

Once incremental sales are calculated for a tactic using one of the above techniques, the ROI for that tactic is calculated using the following formula.

What Is Incrementality Testing?

Media incrementality represents the true incremental contribution of a media channel, campaign, ad set, or tactic to business results.

For example, when a marketer runs an ad on Facebook, Facebook takes credit for 100% of the conversions that ad was in the path of (last-touch attribution). These results can be misleading because they include conversions that still would have happened without being exposed to the ad on Facebook. It is the additional (or incremental) conversions, beyond those that would have converted anyway, that represent the real contribution or impact of the ad. That’s incrementality – the conversions that were truly caused by the media in question. 

 

Why should brands measure incrementality?

Because they don’t have access to all the data outside their own environment, every digital ad platform uses the same flawed last-touch attribution method. Reports provided by ad platforms will never match up with site-side analytics reports or what’s observed in a brand’s sales data. Taking platform reporting at face value is a risky practice that can lead to bad decisions and lost revenue.   

Only incrementality can reveal which media investments contribute to business metrics and by how much. Measuring for incrementality identifies where to eliminate waste and surfaces opportunities to scale, expand and reallocate media spend for maximum growth.

As access to third-party data and user-level tracking end, the accuracy of platform reporting is eroding even further. Measurement that is independent of platform bias and future-proof against the whims of a constantly changing industry is critical for today’s marketers. Incrementality measurement can deliver where methods like last-touch and multi-touch attribution fail.

How Do You Calculate Incrementality?

Incrementality is most effectively measured through proven test and control experiment methodology. By withholding the ad or treatment being tested from a statistically significant segment of the intended audience (the control group) marketers can determine the percentage of the target audience that still converts when they are not exposed to the ad. Subtracting that percentage from total conversions by the exposed audience (the test group) results in the actual incremental contribution, or incrementality percentage, of the media in question. 

Incrementality measurement can vary in complexity from a simple holdout test as described above to multivariate experiments so elaborate they require the expertise of a trained data scientist. But, when carefully designed and cleanly executed, controlled experiments can utilize data from an unlimited number of sources to reveal the incremental impact of just about anything marketers want to test – on any outcome that can be measured. 

In general, the control group should represent a minimum of 10 percent of the total test and control reach. The test group will receive the ad; the control group will not receive the ad. There are multiple ways to build a control audience. Some examples are:

  • Present a placebo ad or basic brand “anchor” ad to an exact replica or mirror audience of the exposed audience
  • Suppress a subset of the target audience from the ad exposure
  • Programmatic executions have counterfactual bid loss data for the target audience that did not win the media auction

The Incrementality Calculation Formula

In order to calculate incrementality, you calculate the conversion difference between the test group and the control group.

(Test Conversion Rate – Control Conversion Rate) / (Test Conversion Rate) = Incrementality

Incrementality Test Calculation Example

Your test group saw 1.5% conversion whereas your control group saw a 0.5% conversion. The control data suggests that, without any media exposure, you would have seen a 0.5% conversion. Keep in mind that conversion could mean leads, sales, profit or whatever metric that is important to your business.

So (1.5% – 0.5%) / 1.5% = 66.7% incrementality in conversions

 

What Channels Make Sense for Incrementality Testing? 

Advertising that generates a lot of impressions but not immediate action like a click still has brand value that ultimately leads to conversions or sales. Channels such as online display, video/YouTube, Facebook, TV, and direct mail all provide impressions, but are not always measured at the click or direct response level. That’s where incrementality testing comes in.
