What is an RSS feed?

RSS is a way for web site owners to let you know what new content they have available within their web sites.

Say you publish a new web page about a particular topic. You want others interested in that topic to know about it. By listing the page as an "item" in your RSS file, you can have the page appear in front of those who read information using RSS readers or "news aggregators"RSS also allows people to easily add links to your content within their own web pages. Bloggers are a huge core audience that especially does this.

Bloggers using popular blogging tools such as Radio UserLand, Moveable Type or Blogger Pro have these feeds automatically created for their web sites. That's why RSS search engines are almost like blogging search engines.Almost, but not quite. Any web site can distribute its content via RSS, so RSS search engines are more than just blog search engines. In addition, not all blog distribute their posts via RSS, so an RSS search engine may miss part of the blogosphere or universe of weblogs that exists.
