Create Universal Metadata Columns for all my sites in tenant.sharepoint.com/sites/

[RioRene]

total newb question.. Using sharepoint online

I would like to create some universal metadata columns that will trickle down to all the sites I am creating under the the /sites/ collection.   Most of the departments in my company use a universal set of metadata columns, and i want to make sure that if someone does a search on one of these universal metadata columns across sites, that they get a good result (assuming they have permissions to search these sites of course)

My first thought was that i was going to have to create one "root" site and put all the sites underneath it as hubs or sites - but that does not sound right to me... because then every department would be /sites/rootsite/department . 

I have created metadata columns in https://tenant.sharepoint.com/ and they dont trickle down.

Any thoughts?
