What Is Marketing Mix Optimization?
This article explores challenges in marketing mix optimization, including ad platform bias and the challenges for each of the most advanced approaches: attribution, incrementality testing, and marketing mix modelling (MMM).

Ad platform bias
Measurement сhallenge
1. Attribution
-
Traditional tools are retrospective, meaning they only assign value to touchpoints after a conversion has occurred. This method falls short for products or services with long consideration phases, as many interactions may be overlooked due to brief attribution windows or cookie deletions. For instance, consider the impact of Safari’s Intelligent Tracking Prevention (ITP).
-
The attempt to piece together complex customer journeys which is impossible.
-
Restrictions such as GDPR, privacy laws, and cookie limitations complicate tracking efforts. Further details are available here.

-
Attribution models often rely on speculative logic, assigning predefined values to certain touchpoints based on assumptions rather than empirical evidence. This makes the process more akin to guesswork than scientific reasoning.
-
The focus on click-based interactions means that channels primarily visual in nature, like video and social media, are undervalued. Despite their significant influence on consumer behavior, these channels are often overlooked because traditional attribution models do not account for non-click interactions.
2. Incrementality testing

- The test-and-learn method is time-consuming and demands considerable effort.
- Newly launched campaigns are hard to evaluate quickly due to the time required for testing.
- It doesn't allow for a holistic marketing mix evaluation for precise media budget planning for a quarter or year, as MMM does.
- Deciding what to test requires formulating specific hypotheses.
- To conduct tests in-house you would need a dedicated team.
- To get buy-in for the experiments you have to explain to your team the test design, audience division, and significance of results etc.
3. MMM (Marketing Mix Modeling)
- Understanding its complexity: The leap into modern MMM requires belief in its effectiveness due to its sophisticated, machine learning-driven methodology. It promises a cookieless and optimal marketing mix, however, the technology is complex, making it challenging for those without a data science background to fully understand how it works.
- Cost: Be prepared for substantial investment, as MMM solutions can cost up to $100,000 per year.
- It’s not for every company: MMM is particularly beneficial for companies with significant digital advertising expenditures, typically more than $1 million per month.
Summary
- Attribution modelling is evolving from its traditional, backwards-looking approach, thanks to AI-driven enhancements by companies like SegmentStream, offering improved accuracy for tracking customer journeys in a cookieless world.
- Incrementality Testing appeals to those who favour a test-and-learn methodology. While it provides valuable insights into the incremental impact of specific marketing actions, it's important to recognize its limitations: the tests require significant time to conduct and fail to offer immediate insights, making it a less agile approach.
- Marketing Mix Modeling (MMM) is undergoing a renaissance, thanks to machine learning technologies from innovators like SegmentStream, Pecan, and Nexoya. Designed for large-scale advertisers with monthly digital ad spends above $1 million, MMM delivers detailed insights into the marketing mix, though it comes at a higher cost.
