Google Analytics does not allow multiple ROI accounts to authenticate using the same Google-based email address. To fix this is simple: you have to create a new Google email address to house the permissions. The integration requires any Google-hosted email address.
For example, your company is ABC, inc. Your work email address of Joe.Smith@abc.com opens up within Gmail, because that’s where it is hosted. This email address would work fine. If that’s not the case, you can should create a new Gmail account to house the integration.
Best Practice: Always create a new Google email just for the ROI Google Analytics integration. We suggest [companyname]firstname.lastname@example.org. To stay with our example, this becomes: email@example.com, or -- if your work address is already hosted through Google – firstname.lastname@example.org.
We suggest putting the “1” there in case future analytics accounts are created. Each Gmail account is only associated with one ROI account and house one integration. If more of your ROI accounts need Google Analytics Integration, you can create email@example.com, etc. This helps for future troubleshooting, and allows for easier access if employees leave.
