Architecture perspective on preventing cannibalization.
How cannibalization develops:
- Content expansion without structure - Topics added piecemeal
- Multiple authors, no coordination - Different people cover same topics
- Blog vs. resource separation - Same topic in different sections
- Historical accumulation - Old and new content overlap
The prevention framework:
Topic-based architecture:
/topic/ (pillar page - comprehensive)
├── /topic/aspect-1/ (detailed subtopic)
├── /topic/aspect-2/ (detailed subtopic)
└── /topic/aspect-3/ (detailed subtopic)
Clear hierarchy = no competition.
The pillar approach:
- One comprehensive page per major topic
- Supporting pages cover specific angles
- Clear internal linking structure
- No overlap in primary intent
For your current situation:
- Identify all topic areas with multiple pages
- Choose one pillar per topic
- Either redirect or differentiate other pages
- Build internal linking to support pillar
