Once you register with this website, it provides email notifications of web page changes in registered email address. Notifications can be updated on a daily basis or weekly basis. But the interesting part is that you can also add update time to generate a fresh report for web page changes (if any).

You can monitor multiple numbers of pages from this website. However, if you exceed a set limit, you will receive notification from the website about your usage limit.


First two websites, Versionista and ChangeDetection, are the most efficient websites in this list.
