Benefits

The most obvious advantage of social bookmarkers is that these let users post bookmarks online, and hence provide a venue for storing links that is independent of the web browser and computer. Hence, even if a person is using a different computer, his/her bookmarks are always accessible over the Web. As for the social aspect meanwhile, as earlier discussed, social bookmarks let the people determine what is important, relevant, or at least interesting in the web. These are shared with contacts or even other members with like interests.

Compared to search engines, meanwhile, the advantage of social bookmarkers is in the human factor that users put into listing of bookmarks online. A search engine can only use algorithms to index websites, and search results are ranked based on relevance to the keyword queries. Social bookmarkers, on the other hand, let the users who understand the content and context of websites to classify and organize the content, and even add short commentaries on links and bookmarks. This makes it easier to look for information, particularly since the system can rank the resources based on how these are favored by other users (in the quantity of "votes" or "links").
