MMM (Marketing Mix Modeling) uses regression analysis and time-series data to decompose revenue by marketing channel. You measure: 'how much revenue came from TV ads vs. search vs. social vs. email?' Then you optimize: 'if we shift $1M from TV to search, what's the expected revenue impact?' Mastery takes 8-12 weeks. Specialists earn 20-30% premium because they recover 5-15% of marketing budgets via reallocation. The skill sits at the intersection of statistics, marketing, and business strategy.

什麼是 MMM Marketing Mix Modeling

Marketing Mix Modeling (MMM) is a statistical technique for quantifying the contribution of each marketing channel (TV, search, social, email, etc.) to overall revenue, then optimizing budget allocation across channels. You collect historical weekly or daily data: spend by channel, revenue, external factors (seasonality, competitor activity). Then you build a regression model that estimates the causal impact of each channel on revenue. The output is a set of elasticities: 'a 10% increase in search spend causes a 8% increase in revenue' (elasticity = 0.8). Using elasticities, you simulate scenarios: 'if we cut TV by 10% and shift that budget to search, what happens to total revenue?' The channel with the highest elasticity gets the additional budget.

❓ 常見問題

How is MMM different from attribution modeling (Google Analytics)?
Attribution (last-click, first-click, etc.) assigns credit to the last/first touchpoint a customer interacted with. MMM looks at aggregate channel spend and revenue, ignoring individual customer journeys. MMM answers: 'if we spend $1M on search, what incremental revenue do we get?' Attribution answers: 'of our $10M revenue, what % came from search?' MMM is better for budget optimization; attribution is better for customer journey understanding.
What's adstock, and why do marketers care?
Adstock models the delayed and diminishing effect of ads. You see an ad on Monday, buy on Friday. That's lag. After seeing an ad 5 times, the next ad is less effective. That's saturation. Adstock functions model both, letting you estimate true channel impact after accounting for lags and diminishing returns.
How much historical data do I need to build an MMM model?
Typically 52-104 weeks (1-2 years) of weekly data across all channels and revenue. Less data = higher uncertainty. More data = better estimates. If you have less than 52 weeks, results will be unreliable. If you have 5+ years, you can detect seasonality and long-term trends.
Can I build an MMM model with observational data, or do I need experiments?
You can start with observational data (spend + revenue over time). However, without causal variation (e.g., a channel you intentionally cut in half), you can't firmly establish causality. A/B tests or geo-experiments (run different campaigns in different regions) strengthen causal claims.
How do I explain MMM results to non-technical stakeholders?
Translate to dollars: 'Each $1M spent on search generates $3M incremental revenue (3x ROI).' 'Shifting $1M from TV to search is estimated to increase total revenue by $500K.' Simple numbers + confidence intervals beat statistical output.
