if your website has rss feeds, its a good idea to add RSS Autodiscovery to your site. if you want to confirm whether or not your site is set up to receive auto discovery by browsers to your site, one way to know its buy looking at the address bar. Firefox is a great browser for this. you can download firefox for free if you dont have it.

this is how it looks on my website which is already configured for RSS autodiscovery settings:

as you can see on the red arrow, i have a little icon on the address bar of my browser which tells the broswer that my web page has rss feeds (xml).

so how do you put it, ok, i will tell you, all you have to do is put this code in between the <head></head> tags:

<link rel="alternate" type="application/rss+xml" title="RSS Feeds By Wallpaperama" href="http://www.example.com" />

thats it

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