What this means in practice
Keyword cannibalization happens when multiple pages overlap so heavily in topic and intent that the site sends an unclear signal about which page should satisfy a query.
Implementation path
- Compare the intent and purpose of overlapping pages before merging anything.
- Consolidate truly redundant pages or differentiate them by audience, task, format, or stage of the journey.
- Use internal links and anchor text to reinforce the preferred relationship.
- Monitor query-to-page associations after changes rather than assuming two URLs competing for one phrase is always a problem.
What good looks like
A strong implementation makes the intended behavior obvious to a visitor, a crawler, and a machine reader. It has one clear purpose, uses consistent signals, and does not rely on hidden assumptions.
