For some time I could not get the RSS Feed icon to appear in my browser, even though I had an RSS feed for my website. Sure you can have a link but it’s real cool when the browser will automatically detect your RSS Feed.
All you do is add
<link rel=”alternate” type=”application/rss+xml” title=”RSS” href=”Feed_URL”>
Put this in your HEAD tag and don’t forget to edit “Feed_URL” to your Feed URL. That’s it, real simple.
