Here is a demo of a macro that watches a web page for a change. Once a page change is detected it will call the macro using the Web Server trigger.
This was created to work around a dynamic page that had no alerting functionality built in and I'm not about to spend all day going back to check the page constantly.
The current JavaScript stops checking for changes once the first change is detected. The JavaScript could easily be modified to continue monitoring but I wanted to keep everything simple and it matches my use case.
