For SEO purposes, and RSS feed can do wonders for you. First off, you can create an RSS feed from your article, your profile links, etc, and place them into RSS directories in order to get them indexed into the search engines. Programs link RSS Bot will actually do all of the work for you. The problem is, you can not send an XML file to an RSS directory. So how would you do this.
There are a few ways around this. First off, you can create your own feed. Head on over to ice rocket, and create a new login. After you are set up, you just add a new channel and create links inside of that channel. Once you are done that that, hit the publish button, and you will have your own RSS feed.
If you have a huge list, this may take a long time. So the next way to use an XML and create an RSS feed is by updating it into your hosting account. This will create an RSS feed in your internet browser. So, you can submit that link into various RSS directories.
Either way works, but it just depends on how many URLs you have, and what the purpose is for the feed. If you would like to have your own domain in your feed, then you should just update your XML into your hosting. If you do not care, creating your own feed in RSS Rocket would just be as good. Good luck!
