Definition - What does Bookmark mean?
A bookmark is a Web browser feature used to save a URL address for future reference. Bookmarks save user and browser time, which is especially useful for Web pages with long URLs.
Techopedia explains Bookmark
A bookmark saves or marks a specific Web page - not just the site's homepage.
Most Web browsers provide a bookmarking feature. A Web bookmark is created by opening the desired Web page and accessing the browser's bookmark menu. Browsers usually provide folder options for related bookmarks. For example, frequently visited sites about stocks, mutual funds and financial advice may be placed in a bookmark menu subfolder for easy reference.
In addition, you can save your collection of bookmarks to 3rd party websites so you can access them from anywhere on the Web. They can then be shared, which in turn, provides a popularity rating.
