Some blogs cover multiple categories, and your readers may only be interested in only a few of the categories, not all of them. You can offer your readers feeds that only cover specific categories. WordPress does offer this capability out of the box, but it’s not the default. Furthermore, you will want to burn all your category RSS feeds with Feedburner. Below I list the steps for adding category RSS to a WordPress blog using Feedburner:
1. Figure out your blog’s category feed. This is most likely the URL for your blog’s category page plus /feed.
2. Burn each category’s feed in Feedburner. If you have many categories, this can be time-consuming. Fortunately, this is a one-time exercise.
3. Add &feed=rss to your wp_list_cats call and save the file. You will see (RSS) appearing next to your category titles with links to each category’s RSS feed.
4. If you want to use the feed icon (or any other image) rather than the word ‘RSS’ to indicate your feed, you can modify the wp_list_categories function (usually found in \wordpress\wp-includes\category-template.php). In that function, set the default feed_image variable to the URL of your feed image. For example, in <a href=”http://www.1keydata.com/blog” mce_href=”http://www.1keydata.com/blog”>Technology Tips</a>, this is set to
‘feed_image’ => ‘http://www.1keydata.com/blog/imgs/feed-icon.png’
5. Set up redirects so that your default category feeds now point to your Feedburner feeds.
