Is RSS only for frequently updated website or any site could use it? what benefits will it have for me if i make an rss for a site without much frequent updates?
It is for everyone. Very non frequent updated websites having a RSS feed will keep your readers updated about any changes in your website. Since you don't udpate the site every time within some frequency it is actually impossible to retain the viewership without a RSS feed.
rss is for everyone irrespective of whether it is an updated site or not. for updated sites... rss feeds will keep the reader informed abt the latest updates... add an rss feed to ur site is even very easy...
Most news sites (including virtually all blogs) will publish what is called an RSS feed which is regularly updated with the latest available headlines and/or articles. The RSS feed is not human readable. It is an XML format which is designed to be read by machines rather than humans. What you can benefits from it?Visitors might get to know your site's update by Rss,For some directories which even require your site has a Rss.
