Weibo is the leading social media platform for people to create, share, and discover content online. Weibo combines an open, real-time form of self-expression with the platform's powerful social interaction, content integration, and distribution capabilities. Any user can create and post microblogs, and attach multimedia or long blog content. The relationships between users on Weibo may be asymmetrical; every user can follow any other user, comment on and retweet any Weibo. The simple, asymmetrical, and distributed nature of Weibo enabled the original Weibo to evolve into a stream of topics with rapid dissemination, multi-party participation, and real-time updates. Weibo helps its advertising and marketing customers promote brands, products, and services to users. Weibo offers a wide range of advertising and marketing solutions to customers of all sizes. The vast majority of the company's revenue comes from sales of advertising and marketing services, including social display ads and promotional marketing ads. Weibo is designed based on the “mobile first” concept, displays content in a simple form of information flow, and provides native advertising integrated with the information flow on our platform. In order to better support the mobile format, Weibo has developed and continues to refine its social interest map recommendation engine, so that customers can target individual marketing and target audiences based on users' demographic characteristics, social relationships, interests, and behavior, so that customers' marketing activities on the Weibo platform have higher accuracy, activity, and promotion efficiency.
