ClickGUARD provides limited support for AdWords Express accounts.
AdWords Express accounts are completely managed by Google. They focus on ads and not ad campaigns so they don’t always feature the ability to block IP addresses like a regular AdWords account. This limits the account in terms of click fraud protection.
ClickGUARD will still work with all underlying campaigns created by AdWords.
What do I do to fully protect my account?
We suggest converting your account to a regular Google Ads account. Contact support in case you need assistance.
