The question
When internal linking is the highest-leverage fix available.
You are deciding whether to invest in internal link structure.
Why it matters
Internal linking is cheap and high-leverage but easy to overlook in favour of new content.
How to decide
IfMoney pages are weakly linked or orphans exist
ThenYes - route authority and fold in orphans first.
IfClusters lack a clear hub-and-spoke structure
ThenYes - build the structure before more content.
IfLinking is already deliberate and complete
ThenNo - invest elsewhere.
