Advantages of Booking.com’s affiliate program:

1) The commission rates are quite generous and if your readers book expensive accommodations, you will get good commissions.
2) It offers a wide variety of hotels and accommodations to promote.
3) There is a wide selection of customizable banners, links and widgets that you can add to your blog.
4) It is a well-known company, especially in Europe.
5) The affiliate interface is user friendly and easy to understand.
6) The website is available in many languages and you can link to the local version.

Cons of the Booking.com program:

1) Due to its flexible cancellation policy, potential guests may make many cancellations.
2) Some readers may not be familiar with Booking.com and may not trust the site.
3) There is a minimum payment limit of €100 and it may take some time to arrive. This means that cash flow is quite slow.
4) The cookie period is limited, so if the reader does not make a booking directly after clicking on your link, you will not receive the commission.
In conclusion, Booking is an excellent choice as a travel-focused affiliate program. It is free and easy to sign up, has no start-up fees or costs, and the system is extremely easy to use.
