Introduction to Feeds
A feed is a function of special software that allows feedreaders to access a site, automatically looking for new content and then posting the information about new content and updates to another site. This provides a way for users to keep up with the latest and hottest information posted on different blogging sites.
There are several different kinds of feeds, read by different feedreaders. Some feeds include RSS (alternately defined as “Rich Site Summary” or “Really Simple Syndication”), Atom or RDF files.
WordPress Built-in Feeds
By default, WordPress comes with various feeds. They are generated by template tag for bloginfo() for each type of feed and are typically listed in the sidebar and/or footer of most WordPress Themes. They look like this:
Finding Your Feed URL
There are times when you want to tell someone your site’s feed address or URL, or you need it to submit it to search engines and directories, many of which now accept feed URL submissions. There are four possible URLs for each of your feeds. Any of these will work.
http://example.com/wp-rss.php http://example.com/wp-rss2.php http://example.com/wp-rdf.php http://example.com/wp-atom.php
Or you can access them like this:
http://example.com/?feed=rss http://example.com/?feed=rss2 http://example.com/?feed=rdf http://example.com/?feed=atom
If you are using custom permalinks, you should be able to reach them through this usage:
http://example.com/feed/ http://example.com/feed/rss/ http://example.com/feed/rss2/ http://example.com/feed/rdf/ http://example.com/feed/atom/
