First, don’t overlook the obvious. The Hosting company might have a monthly report that can be emailed that includes the file data and time stamp information.
If by updated
you mean there would be different text in the downloaded page? All you have to do is download the page and compare it to a previous version of the page. Many freeware applications can compare files. Then just send an email if there are no differences. There is no requirement for this process to be executed on the web server machine or any specific computer for that matter. In fact several freeware FTP applications exist that will report the date/time stamp of the file so all you would have to do is use a FTP application to connect to the site and view the date/time stamp information for the file.
Now if you want to automate the process a simple PC application can perform that functionality.
So for example a simple java console application could be used to download the page and compare it with the previous version downloaded and if 30 days have expired and there are no differences then send the email. The same could be done in C/C++ or .NET, Delphi, VB, etc.
There may be freeware applications available you could use.
Depending on what OS the program needs to be run on the PC, it can be scheduled or configured as a daemon, or you could even run it manually if you wanted to.
