This is quite useful. When the serps change you'll see that in the rss feed, I'm still not sure how it actually displays where the new page ranks, though. http://sitening.com/evilrss/ Here's an example feed for real estate http://sitening.com/evilrss/rss/?q=real+estate&num=10&btnsubmit=Submit The code is available as well, so you can place it on your site. I found this other cool site as well, http://page2rss.com/. It monitors a page for any changes; it's nicer than using something like page update watcher
