Bokee, Daqi, Qihoo, Puffs, Potatoes, Douban ... These descendants of Web2.0, the US dollar has also melted in, the team has also expanded, the beating has also experienced, the media has also reported, the listing has also been planned, and the limelight has also exhausted. Just in making money, it failed to bring more surprises to everyone. The rich who appear on the headlines every day are not really rich. The really rich sit in the office and strategize, never showing their faces. Similarly, websites that really make money will not come out regularly to tell everyone how much money they have made. They are too busy counting money to have time at all. From this point of view alone, we can know that the most profitable website is the most silent website-industry website. Of course, if we take a single comparison, the largest and most paid industry websites are definitely not as many as the most paid search website (Baidu) or even the most paid Web2.0 website, but overall, the industry websites are undoubtedly the most profitable types now. Compared with the descendants of Web2.0 such as bokee, Daqi, Qihoo and Tudou, industry websites can be called their uncles. These industry websites, which were born by the hottest e-commerce fire before the Internet winter, also suffered from frostbite in the Internet Ice Age. Unlike the portals at that time, these "big dinosaurs" fell to the ground and died one after another, but these industry websites survived like flexible "primates". Because of their silence, when it comes to B2B, people only know a monopoly Alibaba and its own news, but not many people know China Chemical Network, Global Textile Network, My Steel Network, Steel Home, First building materials network, China Clothing Network, China Packaging Network, Medicine Business Network, Sex Business Network, Global Hardware Network and Haihong Medicine Network ... They rarely appear in the media, and even many people have heard of them. Different from those websites that spend a lot of money, these websites started relatively poorly, and many of them went to today step by step with more than 100,000 yuan. Now these industry websites are doing well, especially in energy, construction and medical care, and the big ones can make nearly 100 million yuan a year. For example, China Chemical Network has opened its sub-stations to many countries, and also used its own advantages to set up an industry website alliance. Who can say that in the next few years, a giant will not emerge in the industry website? However, it is somewhat puzzling that although many industry websites have been profitable, B2B websites in the industry have not been favored by VC, which is worth studying and discussing (is it related to the narrow industry and small space?
