Keynes publishes case studies reporting measurable outcomes, for example:
- A case study describing a reported substantial increase in paid search growth attributed to CTV using a geo-based test across multiple DMAs, with programmatic audio layered in.
- A case study describing a reported several-fold increase in paid search conversions following extended CTV exposure.
Critical evaluation (methodology gaps):
- These metrics are vendor-published and may be directionally informative, but they typically lack full methodological disclosure (e.g., confidence intervals, seasonality controls, auction dynamics, creative effects, conversion deduplication across devices).
- Geo-holdout tests can be credible, but procurement teams should request:
- Pre-registration of test design
- Justification for test duration
- Details on how DMAs were matched
- Controls for spillover and organic demand
- Replication of results where possible
