RSS autodiscovery
Updated: 05/21/2018 by Computer Hope
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 an RSS icon in the location bar, indicating that an 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 (hypertext markup language) of the website must provide the autodiscovery information in a link element in the head element. For example, the following HTML would permit RSS autodiscovery for the feed located at the rss.mywebsite.org/myfeed web page.
<html>
<head>
<title>Page Title</title>
<link rel="alternate" type="application/rss+xml" title="RSS" href="http://rss.mywebsite.org/myfeed">
</head>
<body>
<!-- web page contents -->
</body>
</html>
