Cancelled bookings still count as sales in IAB Europe's travel ad draft
IAB Europe proposed draft rules for travel ad measurement, requiring networks like Booking.com and Expedia to count bookings at the time of booking, even if later cancelled. A traveller would be considered new to an advertiser after 3 years without a purchase. Feedback is open until October 23, 2026. The rules aim to standardize metrics for travel ads, including a 7-day attribution window for sponsored listings and a 30-day window for display ads.
