How To Create Unique Feeds:
If you’re using WordPress (other platforms also offer the same functionality), there is really not a whole lot of work to be done.
You may already know (or not know) that you can serve up your categorized posts simply by clicking on that category, if you offer it out as a navigation point in your site. In the case of webmarketingtools.org, all posts linked to the “Internet Marketing Resources” category can be found by serving up the URL of, “http://www.webmarketingtools.org/category/internet-marketing-resources/“.
Ready to serve up the RSS feed for that particular category? Tack on the word, “feed” at the end of the URL. Our URL goes from:
http://www.webmarketingtools.org/category/internet-marketing-resources/
to
http://www.webmarketingtools.org/category/internet-marketing-resources/feed
Use this URL and submit it to a Feed Aggregator, like FeedBurner.
