Finding RSS feeds for your Website can be tricky but I came across a fantastic tool at http://www.researchbuzz.org/tools/kebberfegg.pl that enables you to do a search for RSS feeds by keyword.

Try it out and you will see how powerful this is and a great timesaver. It pulls in feeds from a wide variety of sources.

If your building Adsense sites or any other sites where you require some fresh content, RSS feeds are a must.
