Add changes to track and press Track changes to run the first check. The tool will scan your pages and pull raw data to compare with during the future checks.
The next time you run a check (on demand or scheduled), the tool will compare original and current data, find all webpage changes and send you alerts to email, Notification center or telegram.
Please note, that the Value column contains current data, and the deleted strings in the Changes column are red. So, you'll always be aware when someone deletes any data by mistake or on purpose.
