Company Profile Weibo is a leading social media platform for creating, sharing, and discovering content online. It combines public, real-time expression with powerful social interaction, content aggregation, and distribution capabilities. Users can create and post updates with multimedia or long-form content. Relationships on the platform are asymmetric, allowing any user to follow others, comment on, and repost any update. This simple, asymmetric, and distributed structure enables original posts to evolve into rapidly spreading, multi-party conversations in real-time.

The platform assists advertising and marketing clients in promoting their brands, products, and services. Weibo offers a wide range of advertising and marketing solutions to clients of all sizes. The majority of the company's revenue is generated from the sale of advertising and marketing services, which include social display ads and promoted marketing products. Designed with a mobile-first approach, Weibo presents content in a straightforward feed and integrates native advertising seamlessly. To better support mobile formats, the company has developed and continues to refine its social interest graph recommendation engine, enabling clients to conduct personalized marketing and target audiences based on user demographics, social connections, interests, and behavior, thereby increasing the precision, engagement, and efficiency of marketing campaigns on the platform.
