How do you let visitors know you have an RSS feed?


The easiest way is to create a link to your RSS feed and place it on your website. By clicking on it, visitors will be able to subscribe to updates through their RSS reader.
  <a href="URL**">Subscribe via RSS</a>

Another way is to add a following meta tag to the <head> section of the HTML-page:
<head>
  …
  <link rel="alternate" type="application/rss+xml" title="Feed Title*" href="URL**">
  …
</head>

* "Feed Title" - RSS feed title,
** "URL" - Destination feed URL.
When your site contains this meta tag, some browsers add a special icon, which is a link to your RSS feed, located in the right corner of the address bar.
