Organizing content into topic-based silos works better when each silo's pages collectively cover the full related vocabulary of that broader subject area.
Map Related Terms to the Silo as a Whole
Rather than researching related terms page by page, consider the full set of related vocabulary a silo's core topic should cover across all its pages.
Avoid Duplicating the Same Related Terms Across Every Page
Distributing different related subtopics across different pages within the silo produces more comprehensive, less repetitive overall coverage.
Use Related Terms to Spot Missing Pages
A related concept with no dedicated page anywhere in the silo often points to a genuine content gap worth filling.
