Everyone knows that a bookmark is a handy way to remember a favorite web page so you don't have to waste time searching for it again in the vastness of cyberspace. Social bookmarking takes this concept to the next level, enabling Internet users to share their bookmarks with each other in a collaborative fashion. Most often this involves social bookmarking websites where users can create accounts and add their favorite bookmarks, along with keyword tags that help to organize the data and make it easy for others to search.
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.

The big advantage of social bookmarking is that allows individuals to reap and store the fruit of their own research, while enriching the knowledge and experience of others through sharing of bookmarks. This turns the entire online community into a willing army of researchers, creating a semantic web in which the relationships between objects are machine readable. This is important because it helps computers to arrange, search for and present information more efficiently.
Because tag-based systems have no standard set of keywords they can be subject to errors or ambiguity. Mistagging due to spelling errors, the use of tags that have multiple meanings, and the lack of hierarchical relationships between tags are problems that must be addressed for the long-term success of social bookmarking as a way of organizing the Web.
Social bookmarking is also susceptible to corruption that may be introduced by users with an axe to grind, or a product to promote. Spammers sometimes try to bookmark a page many times, or tag it with popular but irrelevant tags, hoping to fool viewers and influence their search engine rankings.
