A permalink (portmanteau of permanent link) is a URL that points to a specific web page, often a blog or forum entry which has passed from the front page to the archives, or the result of a search in a database. Because a permalink remains unchanged indefinitely, it is less susceptible to link rot. Most modern weblogging and content-syndication software systems support such links. Other types of websites use the term permanent links, but the term permalink is most common within the blogosphere.
