SEO cannibalization: detect it before it costs you
Two pages targeting the same query neutralize each other. Quick detection methods and classic remedies.
In short:
- A query alternating between two URLs in Search Console is the classic symptom.
- Merging content solves the majority of detected cases.
- The most effective safeguard sits before publication, in the editorial roadmap.
Cannibalization is a silent problem: no error, no message, just rankings that plateau.
Recognize the symptoms
- Two URLs alternating on the same query
- An abnormally low CTR despite a good average position
- Impressions split between sibling pages
The remedies, by frequency
- Merge content and redirect
- Differentiate search intents
- Canonicalize when pages must coexist
Prevent rather than cure
Upstream control of the editorial roadmap costs one minute per topic. It avoids months of plateauing, and preserves crawl budget.
