How to add RSS Autodiscovery to your site

I sometimes see web sites or blogs that have RSS feeds, but fail to include the one line of HTML that enables RSS autodiscovery. Even some well known blogs such as 37 Signals - Signal Vs Noise omit the feature. Jason Kottke's blog has autodiscovery support on the main page, but not on his entry pages.

Adding that one line of code to your template will make it easier for people to subscribe to your RSS feed. Here's how:

<link rel="alternate" type="application/rss+xml" 
  title="RSS Feed for petefreitag.com" 
  href="/rss/" />

The above link tag should be added inside the head tag of your HTML document.

You will of course need to change the value of the title and href attributes to fit your needs.

If your feed is an ATOM feed you will want to change the type to application/atom+xml.

If you have multiple feeds for the url you can just specify multiple link tags.

When you enable autodiscovery for your rss feed it allows browsers and aggregators to automatically detect the RSS feed when your browsing, and it makes it easy for the user to subscribe to it. Both FireFox, and Safari 2.0 support autodiscovery of RSS feeds out of the box, here's what it looks like when you find one:

That's awesome I wondered why mine wasn't working, thanks Pete!
The trailing slash is illegal according to the w3 validator.
Michael - The trailing slash on the link tag is required if your document type is XHTML, if your doctype is HTML 4.0 then you should not have the closing slash on the tag.
I do not see the RSS icon on Firefox, when I go here, for example: http://www.washingtonpost.com/wp-adv/rss/front.htm i.e., I don't see any autodiscovery for it. On your website, and on the WSJ feed website, I do see the auto-discovery icon on Firefox. I know how to subscribe when the icon is there but how does one subscribe when the icon is not present.
yeah, I use the same trick too :)
Great! Remarkable, I've implemented it and it works.
Is it working for Windows Live Spaces !
Thank you for the useful advice!
