Syndication (RSS)

WordPress has pretty much every syndication option you would ever want for your web site. The RSS 1.0 (aka RDF), RSS 2.0 and ATOM specifications are supported by WordPress and just about any page on your blog has an associated feed that your readers can subscribe to including feeds to latest posts, for categories, comments, well, like we said earlier, for anything you want.

Examples of feed URLs in WordPress.

Posts from site:
http://example.com/feed/
the number of posts returned is set in Settings->Reading.

Comments entire site:
http://example.com/comments/feed/

Individual posts:
http://example.com/comments/feed/

Categories and Tags:
http://www.example.com/?cat=42&feed=rss2
or
http://www.example.com/?tag=tagname&feed=rss2
or
http://example.com/category/categoryname/feed
