Streaming TV: How many incremental travel bookings does it generate?
How many travel bookings does a streaming TV ad generate?

Criteo, the French commerce media platform, plans to offer advertising on connected TVs (CTV) in Germany in 2027 as well. Criteo enables brands and retailers to book ad placements using, among other things, shopping data, and to attribute subsequent purchases to ad exposures.
As an example of successful CTV advertising, Criteo cites a travel platform with a 61x return on ad spend (ROAS). In other words, €61 in revenue was attributed to the campaign for every euro spent on advertising. But how many of those trips would have been booked without the ad? Criteo does not disclose whether there was a control group that did not see CTV ads. I would check this with an incrementality test.
Across the wider e-commerce market, common estimates of analytics maturity suggest that well under 5% of companies regularly run genuine geo-holdout tests. Most still optimise using the platforms’ own click data.
The reason is clear: a geo holdout requires additional expertise in statistics and tools, and the holdout also means forgoing some short-term revenue for the advertiser. But the insights can be many times more valuable.
When an advertising platform or agency quotes a high ROAS (which is ultimately too narrow a measure), I always ask how much incremental revenue the campaign generated — and how it was measured.
