PPC Protect doesn’t limit the number of domains you can use in your account - you can use an unlimited number of domains as long as their AdWords ads are managed by your MCC/AdWords account.
To protect another domain, make sure you are managing an AdWords account that uses this domain and then set “Fraud Protection” to “On” within the accounts section of the PPC Protect dashboard. It’s that simple!
If you don't see the account you wish to protect in the list, please click on "Update Adwords Account Data" in the Accounts tab:
Note: By protecting new domains your total AdWords spend may require you to be on a higher tier PPC Protect plan (if your total spend reaches your current threshold). Don’t worry though, we’ll email you with plenty of notice if this happens.
