Want to follow a certain web page only and not the entire site update? FeedBeater will beat the feeds out of those web pages. It can also be used to syndicate content changes on websites that do not offer RSS updates.
How it works
FeedBeater is powered by Diffbot, a syndication engine which monitors any URL for changes in content, then classifies and decodes the document’s structure.
By identifying new content, filtering out unimportant content (comment counters, ads, etc etc), clean and intelligent RSS feeds can be built from any URL.
All you need to do is paste the URL you want to syndicate and it will update you whenever a change is made on that page. This is great if you want to keep track of websites that are under construction or get updates from auction pages.
Tip: You can use their script which will allow users to syndicate any page on your website. There is also a bookmarklet available which makes the creation of RSS feed for any URL just a click away.
