How multi‐channel marketing mix works

Marketing Mix Modeling

• the ability to link offline brand advertising to business outcomes and understand how on‐and offline marketing interact

• Steps:– Attribution– Optimization– Allocation

Page 4: Multichannel Marketing Mix - PMSA Mix Modeling • the ability to link offline brand advertising to business outcomes and understand how on‐ and offline marketing interact

Challenge of Multichannel Mix

• Spillovers across channels and carryover within channel complicate attribution

• Managerial actions upon which outcomes depend on are not randomly set– Outcome is not dependent on a experiment– Endogeneity

• Optimization – how do you handle uncertainty?

Dynamic Optimization

FromFischer, Wagner, and Albers, MSI Working Paper 13‐114 (2013)

Allocation Mechanisms

• Naïve Allocation: – equal distribution across all allocation units –specific marketing activity for specific product

• Percentage‐of‐sales rule:– Percentage of previous year’s sales for each product

• Attractiveness allocation heuristic• Numerical optimization

Page 7: Multichannel Marketing Mix - PMSA Mix Modeling • the ability to link offline brand advertising to business outcomes and understand how on‐ and offline marketing interact

Modeling Spillovers

• Simultaneous equation systems– Sales in each channel as a function of budget allocation across different marketing instruments

– Modeling direct effect and indirect effects– Multi‐period modeling with aggregate data– Complement with individual level analysis

• Challenges– Endogeneity– Having enough variation in data 

Page 8: Multichannel Marketing Mix - PMSA Mix Modeling • the ability to link offline brand advertising to business outcomes and understand how on‐ and offline marketing interact

Challenges in Modeling

• Iterative development in model– Initial to final involves adding, removing variables, interaction terms, functional forms

• New marketing instruments added – e.g. social media– Drastic changes in parameter estimates– Collinearity problems– Granularity of data

What’s the advantage?

• We can specify priors for estimates based on external information– Experiments– Prior studies– Managerial intuition

• Hierarchical Bayes– Higher level parameters as priors for lower level estimates

– National level estimates used as market level priors

Case Study 1 ‐ Retailer

• Sales through multiple channels• Click‐based attribution model for online sales• Display experiments – spillover to search• Tracking impressions social media, experiments• Integrate offline marketing spend• Develop multichannel marketing mix –Bayesian methods

Case Study 2 – Insurance Industry

• Measuring spillovers using aggregate data• Developing individual level path data – data warehousing capability

• Linking online multichannel spend along TV spend

• Modeling using hidden Markov models• Dynamic optimization methods for allocation
