There are 3 ways ClickGUARD can access a Google Ads account:
manager (MCC) access - preferred
direct access via your Google account
access via linked MCC account
All access types are valid and safe and they all ensure ClickGUARD can work with your Google Ads.
Manager (MCC) Access
When you add your Google Ads account to our manager (MCC) hierarchy, ClickGUARD can access your account to protect and optimise your campaigns.
This is the preferred way of integrating ClickGUARD as it allows our support team to assist you with setup and provide better insight into what's going on with your Google Ads account. Simply put, with your permission, our team is able to access your Google Ads UI and provide immediate support.
All changes to your campaigns made by ClickGUARD will appear in your Google Ads Change History as made by ClickGUARD user.
Direct (oAauth) Access
You can authorise ClickGUARD to access your Google account which you use to access one or more Google Ads accounts. This is widely known as Google oAuth.
While the process of linking your account is significantly faster in this case, when you don't add your Google Ads account to ClickGUARD's MCC hierarchy our team is unable to provide on-boarding assistance and immediate support, as we are unable to access your Google Ads UI.
All changes to your campaigns made by ClickGUARD will appear in your Google Ads Change History as made by the user you authorised.
There is a misconception that oAuth access is more secure. You can read more about that here.
Access via Linked MCC
You can link your manager (MCC) account with ClickGUARD either by adding it to ClickGUARD's MCC hierarchy or by authorising your Google account with access to the given manager account.
When you link a manager account with ClickGUARD, regardless of the access type you opted for, ClickGUARD can access all Google Ads accounts managed by your MCC account.
