# Retail media measurement: quantifying impact in the third wave of digital advertising

Retail media is the fastest-growing advertising channel, but measurement remains challenging due to walled gardens and attribution complexity.

## The retail media measurement challenge

Retail media networks operate as walled gardens with limited data sharing. Each retailer has different metrics, attribution windows, and reporting capabilities.

## Measurement approaches

1. Platform-reported metrics - Baseline, but limited to in-platform conversions
2. Marketing mix modeling - Include retail media spend in your MMM
3. Incrementality tests - Geo-tests or holdout experiments where possible
4. Halo effect analysis - Measure impact on non-retail channels

## Integrating retail media into MMM

Challenges:
- Data availability varies by retailer
- Need to separate retail media from trade spend
- Account for in-store vs. online sales

## Best practices

- Standardize metrics across retail media networks
- Build retailer-specific MMM modules
- Test incrementality where platforms allow
- Track halo effects on brand search and DTC sales
