How do travel websites generally make profits?

Travel websites generally make profits by earning commissions and advertising revenue. 1. Earning transaction commission means that the user makes a reservation through the interface of the website, and the reserved website or hotel gives the website a part of commission. A common way is to throw the predetermined steps to a predetermined website (such as Booking.com). After the user makes a successful reservation, the reserved website will pay a part of the commission for the travel website. (< Another emerging way is to do it in travel websites. That is to say, when the user intends to make a reservation, he will not jump to the reservation website to the webpage, but stay at the travel website all the time, but the travel website will still hand over the user information and payment information to the reservation website for processing. Advertising revenue means ... as we all know. There are several methods: CPC(costperclick) refers to the cost that the merchant has to pay for each click. For example, I am Xiao Yi Hotel, and I put my hotel link or information (depending on the company) on the travel website, so every time a user clicks on my link or information, I have to pay a certain fee to the travel website. CPM(costperiimpression) refers to the cost of each visit. For example, if I have a Xiao Yi hotel page on the travel website, how much do I have to pay for each visit? Additional services, such as Businesssubscription. For example, I hope that Xiao Yi Hotel has not only very basic information, but also additional introductions or pictures on the travel website. In this case, I have to pay.
