What are RSS feeds?
Rich Site Summary (RSS, also known as Really Simple Syndication) is a method of publishing your site's updates. The benefit of an RRS feed is that is allows subscribed users to automatically receive any updates from your website.
RSS feeds can be created for your entire site, or for a specific section of your site. For instance, you can have a “Blog” feed that only publishes your latest blog post, and another “Products” feed that publishes your most recently added products.
