A big challenge for Sina is monetizing the massive Weibo following. Sina has taken several steps in that direction, and is reportedly developing a "pay-for-forward" feature. The feature will enable users to pay to have a message forwarded by an account with a large following. Sina plans to keep 20% of the revenue generated from "pay-for-forward" fees.[16]

Local content

Internationalized services have a common layout which consists of sections like news, information, infotainment and email services with localized content.}

Localization involves political censorship. As with all internet content providers operating within mainland China, the web pages which are geared toward mainland China audiences have internet censors controlling the discussion for sensitive political content. In addition, the news from comes from local newspapers, which in the case of mainland China are themselves subject to censorship by the government. This censorship does not extend to pages and forums which are not intended for audiences within mainland China.

Online news provides a lot of feature news as the focus of the lead story or the main photo. On the other hand, its domestic political news is sourced from The People’s Daily or Xinhua News Agency. Compared to conventional medium for news distribution, is a platform for news articles from the traditional media. That means, according to its CEO, Wang Zhidong, would never hire journalists (Xin, 2000).

Network technology

According to the company's published information, Sina.comXpressTM and Sina.comPlusTM are's two main exclusive technologies, which bring ease-of-use benefits and enable the audience of Big 5 (traditional Chinese character), and GB (simplified Chinese characters) to view the webpages sourced from around the Chinese communities of the world.
