RSS (Really Simple Syndication) is a lightweight XML format designed for sharing headlines and other web content. RSS is a defined standard based on XML with the specific purpose of delivering updates to web-based content. Using this standard, webmasters provide headlines and fresh content in a succinct manner.
An advantage of RSS Feeds:
*RSS feeds provide an easy, almost automated way to update your site's content.
*It allows viewers the opportunity to decide what they want to read without forcing them to go anywhere, which they're likely to appreciate.
*It allows both human readers and search engine spiders to find content based on keywords without compromising the quality for either one.
* It's an excellent way to market any type of website, but especially blogs since these tend to be updated much more frequently and consequently have more subscribers.
* It's a great method for keeping people informed during a collaborative effort.
