I run several travel websites in Europe and I could not earn as much money with Expedia as with Booking.com. I assume that Booking.com has a very strong brand here and a lot of trust for European people. I can highly recommend the affiliate program of Booking.com as an alternative to Expedia. In their affiliate center, you can use many tools to create ads like deal finders, search boxes or own banners.
