As you create an rss feed to your website or web log you can essentially syndicate your website or web log, much like television shows syndicate their content.
The full meaning of rss feed stand for "rich site summary". Rss is a way to stream up to the minute news and updates on your blog around the world via the internet. Readers of rss streams, use a content reader program called a feed reader or aggregator.
the feed reader, or aggregator, checks websites where the user has subscribed to see if there is any new and updated information and if the site has been updated then the feed reader will copy that new information so that the reader can read it.
