In the case of weblogs, current entries are always pushed back by new ones, which changes the position of all entries with each new entry. The permalink creates a fixed link to a weblog entry, regardless of which web page of the weblog this entry has been moved to by newer entries.
A permalink is a permanently present link that leads to an entry, even if it has been moved backwards through several web pages. Permalinks are marked as such with the name permalink or link, but they can also be related to the time, or marked by a hash (#).
If the web address of the permalink is called, the entire post with all comments appears. This way a specific post can be saved in the bookmarks. In contrast to a normal link that points to a web page, permalinks offer the advantage of linking posts within a web page, thus condensing the blogosphere.
