Connect multiple Google Business Profiles within a campaign
In order to connect multiple GBPs, go to the campaign's Integrations page on the left side menu, go to Local, and select Google Business Profile.
If you haven't yet connected a GBP to the campaign, you'll be presented with the first time setup options. Click "Connect New Account".
If you already have a GBP connected to the campaign, it'll show you the details of the page that is connected. Click "Switch Account" to proceed.
Either way, you'll then be able to either select the Google Business Profiles you'd like to connect from a list of Google accounts already connected to your AA account, or add a new one. In total, you can connect up to 50 GBP locations within one campaign!
Once you've selected the relevant pages for the campaign, hit the "Save" button.
