The navigation model defines how pages are exposed and related for discovery.
It determines whether structure is explicit, implicit, or emergent.
This decision affects how users traverse content and how maintainers reason about completeness and coverage.
Navigation choices tend to harden early and resist change.
Decision Space
Navigation models commonly range between fixed, authored hierarchies and dynamic, system-generated paths.
Many sites combine both, but the dominant model shapes behavior.
The tradeoff is not between simplicity and complexity, but between predictability and adaptability.
Authored Navigation
In an authored model, navigation is explicitly defined.
Links, menus, and hierarchies are constructed by maintainers rather than inferred by the system.
- Clear, intentional structure
- Predictable discovery paths
- Manual effort required as content grows
Gaps and omissions are visible.
Maintenance effort increases with both content volume and structural ambition.
Generated Navigation
In a generated model, navigation emerges from content attributes.
Categories, tags, and relationships produce paths automatically.
- Low marginal cost for new content
- Automatic coverage as volume increases
- Reduced editorial control
Structure can become opaque over time.
Redundancy and fragmentation accumulate without explicit intervention.
Persistent Tradeoffs
Authored navigation favors clarity and intention.
Generated navigation favors scalability and breadth.
The decision determines whether maintenance effort is concentrated in navigation or displaced into content discipline.
Reversal after growth is difficult.
