Hotwire found a way to replace banner ad revenue by allowing users to compare Hotwire's prices with other travel sites directly from Hotwire's search results. This increased the likelihood users would find Hotwire had the lowest prices. Hotwire was paid for each search initiated on other sites. It worked well because many users cross-shop, it was presented as a helpful feature rather than ads, and Hotwire's exclusive deals and low prices were highlighted. This led to a 2000% increase in revenue over 3 years without cannibalizing Hotwire's own sales.
