What is the profit model of Hotel Reservation Website?

Let me tell you about their profit model. They have established a cooperative relationship with local hotels, only a multi-line cooperative relationship. Let me give you the simplest example: A B C D E F is a local hotel, and I put all their services on my website. As long as a user contacts me to stay in my partner hotel, no matter which one, I will earn the commission I got before the hotel negotiation, and the hotel will also pay the commission according to the service size. In the early stage, the profit model was like this. In the later stage, when my website already has traffic guarantee, that is to say, if you are from Nanchang, and you set up this website so that people who come to Nanchang to play, live and travel only recognize your website entrance, then your profit model is that the hotel is looking for you, hehe, they want to go and give you benefits. In addition, the distribution service advertising space of the website has also become one of the profit models in this period. Websites like this have diversified profit models, such as providing telephone recharge, refund, membership star system and so on.
