What it means in practice
Look-to-book ratio measures how many searches it takes to produce a booking. A high look-to-book ratio means a lot of shopping for each sale, which is normal in travel because travellers compare extensively across OTAs and metasearch before committing. Tracking it shows how efficiently traffic from each channel converts.
For affiliate programs, look-to-book is a quality signal. A partner sending high-intent traffic produces a lower look-to-book ratio and more bookings per click, while a partner sending broad, untargeted traffic produces many looks and few books. It complements conversion tracking and helps an operator value partners on outcomes, not volume.
A travel brand running its own affiliate program uses look-to-book alongside booking-confirmation attribution to identify which partners and channels actually drive confirmed bookings rather than just searches.
How Track360 handles this
Track360 reports bookings and conversion quality per partner and channel, so an operator can compare look-to-book performance and reward the partners whose traffic converts to confirmed bookings.
Frequently Asked Questions
Common questions about look-to-book ratio, how it works in affiliate programs, and where it shows up across Track360's supported verticals.
Look-to-book ratio is the number of searches or shopping sessions divided by the bookings completed. It measures how efficiently travel traffic converts, with a high ratio meaning a lot of shopping for each sale and a low ratio meaning efficient conversion.
