RSS autodiscovery is the ability of a web browser to automatically detect a website's RSS syndication feed. If the browser detects the feed automatically, it displays a RSS icon in the location bar, indicating that a RSS feed is available for subscription. Most modern browsers support RSS autodiscovery, including the newest versions of Chrome, Firefox, Safari, and Internet Explorer.
For a browser to auto discover a website's RSS feed, the HTML of the website must provide the autodiscovery information in a link element within the scope of the head element. For example, the following HTML would permit RSS autodiscovery for the feed located at the rss.mywebsite.org/myfeed web page.
<link rel="alternate" type="application/rss+xml" title="RSS" href="http://rss.mywebsite.org/myfeed">
