Keyword cannibalization happens when multiple pages compete for the same search intent. This can confuse search engines and split your ranking strength.
How to spot it
Look for multiple URLs ranking for the same keyword or topic. If search performance is bouncing between pages, cannibalization may be part of the issue.
How to fix it
- Merge overlapping content when appropriate
- Clarify the purpose of each page
- Use internal links to point to the strongest page
