Do you have web pages you check routinely? Maybe a page that doesn't have an RSS feed that you would like to keep an eye on? PageTiki can help you by monitoring web pages and notifying you when they change.
By tracking the visual content of web pages, PageTiki is able to consistently detect important changes in a website. The change detection routines are smartand ignore insignificant changes such as timestamps, page counters and minor elements that don't comprise the main contentof the page. For complicated pages that have many dynamic elements, PageTiki will establish a threshold for routine changes and then alert you to significantchanges that are greater than average.
PageTiki is completely free. Signing up takes only 10 seconds and each account comes with a custom RSS feed that streams your web page changes. If you don't have an RSS reader, grab one, it'll really make this service pop!

A similar service is Page2RSS. Simply visit the site, add the URL of a website you want to keep an eye on, and Page 2 creates an RSS feed for the site which you can add to the feed reader of your choice. It couldn't be easier to use, and I can vouch for the fact that it works really well.
