Social bookmarking is a method for Internet users to share, organize, search, and manage bookmarks of web resources. Unlike file sharing, the resources themselves aren’t shared, merely bookmarks that reference them. In a social bookmarking system, users save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine. As these services have matured and grown more popular, they have added extra features such as ratings and comments on bookmarks, the ability to import and export bookmarks from browsers, emailing of bookmarks, web annotation, and groups or other social network features. The in-complete list below includes the most popular social bookmarking sites in Chinese language. QQ Bookmarks (QQ 书签): QQ Bookmarks keeps all your bookmarks on a central server so that you can access bookmarks from anywhere on the web. The site also has a screenshot tool that represents the page bookmarked and adds visual elements to user experience. You have to create a QQ account/number to get access to this service. Baidu SouCang (百度搜藏): Baidu Soucang is a social bookmark service provided by baidu corp. of china. It provides popup windows to add link to user’s list.

Drawer (抽屉): Drawer has the sleekest design of all the social bookmarking services. High quality web design with lots of white space and easy navigation makes users happy.

With social bookmarking, you can submit individual pages of your site or blog, thus if your blog/website has good content on it, chances are that several users will link to your content, thus getting you plenty of relevant links. It is one of the most important methods to getting traffic to your site. Additionally, a social bookmarking system can rank a resource based on how many times it has been bookmarked by users, which may be a more useful metric for end users than systems that rank resources based on the number of external links pointing to it.
