Topic cluster
A group of linked pages that cover one subject from many angles, around one main page.
In plain English
Clusters help readers and machines see how pages relate. Each supporting page answers one specific question and links back to the main page, which links out to all of them.
In practice
A main “Bathroom remodeling” page links to pages on costs, timelines, walk-in showers and permits, and each of those links back.
