A web feed (or syndicated feed) is a way for publishers to provide their users with access to their regularly updated information. End users will utilise applications such as a news reader to subscribe to these feeds enabling them to keep up to date with the content of the sites. Some news readers themselves are online applications (such as Google Reader).
A number of different technologies are used by site owners to distribute these feeds – such as RSS and atom. Popular, modern news readers will be able to cope with most types of feed. One of big advantages to Internet marketers is that it will often encourage syndication of your content and the use of links to your articles on other sites as these feeds can be read easily by computers and plug ins to other websites. If you see a site with ‘Latest News From The BBC’ and some links to BBC news stories there is a good chance they have obtained this by reading a BBC news feed automatically.
