What are the characteristics of the operation mode of Facebook advertising business?

I always thought that the only thing facebook did well was that it was global. This year, smartphones in India are driving traffic to fb. What is the next big market? Gee, there is no next big market. Social network, an unnecessary substitute product, is certainly short-lived, not to mention that fb has no big profit block except advertisements on social platforms. Tencent is much smarter in this respect, and it can survive for a while by relying on the world's largest game company. One is to answer from the user's point of view. The advertisement fb showed me was accurate and I was interested. Two hours ago, I searched a jeans brand on google. After a while, I opened fb. The fb account of this brand has been pushed on my home page. Facebook has formed a positive incentive for advertising content. Facebook's advertising pricing contains many factors, but it is very important to provide price concessions for high-quality advertisements (exquisite pictures, meticulous text and high user participation), which improves the user experience and urges advertisers to put in high-quality advertisements. Comparing the advertisements in Weibo and FB, we can find that the quality of advertisements in FB is generally much higher than that in Weibo. It's hard to imagine that I will see He Jie's fitness instructor on FB ... and watch it so many times. So I think the whole advertisement is more transparent and clear. At the same time, a clearer process makes advertising easier and lowers the threshold for advertisers to place advertisements. Compared with Coca-Cola, a company that advertises cars and mobile phones in a circle of friends, the threshold is much lower. Of course, this is determined by the nature of social media itself, and Weibo's norm is more suitable for FB. However, after using FB in Taiwan Province Province for several months, I personally always feel that in their online life circle, FB has both the functions of Weibo and friends circle, and users' choices are relatively fixed and unique. When using FB to contact friends, you can feel the dynamics of friends and accept all kinds of complicated news (friends circle can't accept so many advertisements).
