Before integrating Google Local Service Ads you will need to have a manager account, this is a Google feature that was previously known as My Client Center (MCC), and then link it to your client's GLSA account.
How to set up your Google Manager Account
The first step is to visit the manager accounts site, here. And then click on the "Create a manager account" button.
It will ask you to sign in to your Google account (if you're not signed in).
On the next screen, enter a display name and then select "Manage my accounts." Click "Submit" to confirm the changes.
You may need to click on "explore account" to proceed to the next screen.
Once the Google Ads dashboard loads, click on Accounts> Sub-account settings.
Then, click on the blue "+" button, and select "Link existing account."
Enter your clients' Google Local Service Ads account IDs (you can add multiple clients at once) and add the profile who will become the manager.
Click the Send Request link at the bottom to complete this step.
Open a new Incognito browser window and log in as the client on Google Ads. Go to the sidebar menu and select "Account Access".
Click the "Managers" tab, look under the Link request section to find the request, and click "Accept".
Your Manager's account is now properly linked and you may now proceed to the next step which is to connect Google Local Service Ads on AgencyAnalytics.
