Can someone clarify something for me.

I have approx 80 pages on my website. I have only created one rss feed page
Each of the pages have a link to the same rss page. The rss page has links to the primary pages of the website.

What i want to achieve is that if i update one of these primary pages then the visitor gets a notification. I am not sure that the setup i have at the moment does what i want. Can someone advise me what structure i need.
