E-commerce. Mainly B2C(B stands for merchants and C stands for consumers), C2C and B2B, among which B2B mainly sells membership fees, C2C mainly collects transaction intermediary fees, and B2C can directly collect corresponding profits. 5. Search for bids. For example, Google and Baidu in China make money by selling keywords and location resources of search pages. 6. Mobile value-added services (SMS). Although this business is not popular in Europe and America, it is very developed in East Asia such as China, Japanese and Korean.

In addition, there are many ways to make money on the website, including paid games, online consultation and education, online community, making friends and so on. In fact, the ever-changing profit model of the Internet is developing in a three-dimensional and in-depth direction, and many new profit models are constantly emerging. For example, the charging model of the most popular blog site recently is under discussion.
