Adding a hyper link for an RSS or Atom feed on your web page works, but that's not all you can do. By adding a link to the head section of the page you can allow your users an alternative method of picking up your feed.
To add an RSS feed use this.
<link rel="alternate" type="application/rss+xml" href="http://www.example.com/rssfeed.xml" />
To add an Atom feed use this.
<link rel="alternate" type="application/atom+xml" href="http://www.example.com/blog/wp-atom.php" />
These are both XHTML examples. To do this in HTML just remove the slash on the right hand side like this.
