Media Mix Modeling: How to Measure the Effectiveness of Advertising in Python

Abstract: 

Media Mix Modeling, also called Marketing Mix Modeling (MMM), is a technique that helps advertisers to quantify the impact of several marketing investments on sales. If a company advertises in multiple media (TV, digital ads, magazines, etc.), how can we measure the effectiveness and make future budget allocation decisions? Traditionally, regression modeling has been used, but obtaining actionable insights with that approach has been challenging.

Recently, many researchers and data scientists have tackled this problem using Bayesian statistical approaches. For example, Google has published multiple papers. LightweightMMM is a python library for MMM considering Media Saturation and Ad-stock.

However, if you are not careful with the data preparation and modeling, you will often lead to incorrect results and interpretations in real business. Therefore, it is essential to understand how to avoid the pitfalls.

In this talk, I will show the key concepts of a Bayesian approach to MMM, its implementation using Python & R, and practical tips.
