I am adding this article here so that I can have it for reference later. Writing and working on WordPress feeeds has been tough, so this is here for my reference so that I am able to make changes necessary and quickly find what I need later. I hope that it helps you as well.
This article covers each of the many ways to access your WordPress-generated feeds. Several different URL formats are available for the various types of WordPress feeds — posts, comments, and categories — for both permalink and default URL structures. For each example, replace “http://domain.tld/” with the URL of your blog. Note: even though your blog’s main feed is accessible through many different URLs, there are clear benefits to using a single, consistent feed URL throughout your site.
WordPress Post-Feed Formats for Permalinks
If you have permalinks enabled on your site, your main-content (posts) feed is accessible via the following URLs, depending on which feed format you would like to use:
http://domain.tld/feed/(RSS 2.0 format)http://domain.tld/feed/rss2/(RSS 2.0 format)http://domain.tld/feed/rss/(RSS 0.92 format)http://domain.tld/feed/rdf/(RDF/RSS 1.0 format)http://domain.tld/feed/atom/(Atom format)
WordPress Post-Feed Formats for Default URLs (non-permalink)
By default, your main-content (posts) feed is accessible via the following URLs, depending on desired format:
http://domain.tld/wp-rss2.php(RSS 2.0 format)http://domain.tld/wp-rss.php(RSS 0.92 format)http://domain.tld/wp-rdf.php(RDF/RSS 1.0 format)http://domain.tld/wp-atom.php(Atom format)
WordPress Post-Feed Formats via Query String (non-permalink)
Alternately, your main-content (posts) feed is also available at the following URLs, depending on desired format:
http://domain.tld/?feed=rss2(RSS 2.0 format)http://domain.tld/?feed=rss(RSS 0.92 format)http://domain.tld/?feed=rdf(RDF/RSS 1.0 format)http://domain.tld/?feed=atom(Atom format)
Display your Default Post-Feed URLs
To determine/display the default posts feed URL for your blog’s main content, place any or all of these template tags into a useful location in one of your theme files:
<?php bloginfo('rss2_url'); ?>(RSS 2.0 format)<?php bloginfo('rss_url'); ?>(RSS 0.92 format)<?php bloginfo('rdf_url'); ?>(RDF/RSS 1.0 format)<?php bloginfo('atom_url'); ?>(Atom format)
WordPress Main Comments Feed
Your blog’s main comments feed is available only in RSS 2.0 format, but there are several URL options from which to choose:
http://domain.tld/comments/feed/(Permalink format)http://domain.tld/wp-commentsrss2.php(Default format)http://domain.tld/?feed=commentsrss2(Query-string format)
Display your Main-Comments Feed URL
To display the default URL for your main comments feed, add this template tag to your theme file and load the page in your browser:
<?php bloginfo('comments_rss2_url'); ?>
Post-Specific Comment Feeds
By default, every post also delivers its own feed featuring all of its comments. To display feed URLs for individual, post-specific comment feeds, place this template tag anywhere in the main post loop or comment loop 1:
<?php comments_rss_link('Subscribe to comments on this post via RSS-2.0 feed'); ?>
Alternately, to display the comment feed URL for any specific post, simply append either of the following to the original post URL:
feed/(Permalink format)?feed=rss2(Default format)
Here is an example of each method for a generalized post URL:
http://domain.tld/individual-post/feed/(Permalink format)http://domain.tld/individual-post/?feed=rss2(Default format)
Update: When using default (non-permalink) URLs, the post-specific comment feeds are available via the following format:
http://domain.tld/?feed=rss2&p=123
..where “p=” references the post ID .
Category Feeds
To display individual category feed URLs, use either of the following formats 2:
http://domain.tld/category/categoryname/feed/(Permalink format)http://domain.tld/wp-rss2.php?cat=33(Default format)
