Walled Garden
A walled garden is a closed ecosystem where a platform controls access to data, distribution, and measurement (common in advertising and analytics).
For marketing leaders, it affects attribution, MMM, and the ability to prove AI-driven lift. For AI solutions, it influences what data you can access and how you model outcomes.
Explanation
Walled gardens can limit cross-platform measurement and transparency, requiring incrementality approaches and careful first-party data strategies.
Marketing Relevance
For marketing leaders, it affects attribution, MMM, and the ability to prove AI-driven lift. For AI solutions, it influences what data you can access and how you model outcomes.
Example
A platform provides aggregated conversion reporting; you use incrementality tests to validate true lift instead of relying on reported attribution alone.
Common Pitfalls
Overtrusting platform-reported performance and ignoring causal measurement.
