The usual failure
A hub that is a dump of posts. Supporting pages do not point up. Internal links are 'related' widgets.
What to make true
A hub and supports that share links on purpose. Planned before publish. Authority is a structure, not a plugin.
Worked example
Keep it this plain. A team uses content cluster as if buying the software installed the meaning. It did not. A hub that is a dump of posts. Supporting pages do not point up. Internal links are 'related' widgets. The move is not a new integration. A hub and supports that share links on purpose. Planned before publish. Authority is a structure, not a plugin.
