Growth Marketing: Data-Driven Experimentation at Scale

Growth marketing combines marketing, product, and analytics to drive sustainable growth through continuous experimentation.

Core Growth Marketing Framework

AARRR Metrics:

• Acquisition: How do users find you?
• Activation: Do they have a great first experience?
• Retention: Do they come back?
• Revenue: Do they pay?
• Referral: Do they recommend you?

Growth Experimentation Process

1. Identify Bottlenecks: Analyze metrics to find growth constraints
2. Form Hypotheses: "If we change X, Y will improve by Z%"
3. Design Experiments: A/B tests, multivariate tests, cohort analysis
4. Run Tests: Collect statistically significant data
5. Implement Winners: Scale what works

Growth Marketing Tactics

Viral Loops: Encourage users to refer friends (Dropbox, Uber)

Onboarding Optimization: Reduce time-to-first-action

Pricing Experimentation: Test pricing, packaging, trial lengths

Channel Testing: Identify highest-ROI acquisition channels

Retention Playbooks: Reduce churn through engagement sequences

Key Metrics to Track

CAC (Customer Acquisition Cost): Total marketing spend / new customers

LTV (Lifetime Value): Revenue from customer - acquisition cost

CAC Payback Period: Months to recover acquisition cost

Viral Coefficient: # of new users each user brings (>1 = viral growth)

Engagement Rate: % users taking core action weekly/monthly
