Hi Alessandro,
I’m glad that shed some light!
Regarding your most recent question, if you were an agency managing multiple brands or SMBs in one account, it would be best to organize these by Folder and Label.
So, for example, if you would create all of the locations in the Knowledge Graph, but when creating them move them into the coresponding folder: SMB_1, SMB_2, and SMB_3. You could further sub-organize them by creating labels that correspond to the SMB and another identifier, like region. These could include: SMB_1_East, SMB_1_West, SMB_2_East, SMB_2_West, etc.
While all of the information would still be stored in one place, the Knowledge Graph, this setup would allow you to organize the data in format that’s easy to divide and organize.
I hope this helps!
