7.3. Submitting Feeds
The next step is to submit your syndication feed to syndication aggregators and search engines. The RSS Compendium provides a great list of sites for submitting syndication feeds for inclusion at http://allrss.com/rsssubmission.html. The RSS Specifications site also has an extensive list of sites that maintain syndication feed databases at http://www.rss-specifications.com/rss-submission.htm.
It's a good idea to continue to submit your feeds as you add content items. If you are publishing multiple feeds, however, this can become an unpleasant chore, so you may want to use a tool that automates the process. RSS Submit is one such programit's available for download at http://www.dummysoftware.com/rsssubmit.html in an evaluation version or (with free updates) for $35.
The updates to RSS Submit add new syndication indexes as they come online, and make sure the submission pages for older feeds stay accurate.
