Cannibalisation checks help make content decisions clearer.
Quick answer
Keyword cannibalisation happens when multiple pages compete for the same or very similar search intent. You can spot it by reviewing ranking URLs, Google Search Console queries, content overlap, internal links and whether Google keeps switching which page it ranks.
Cannibalisation is really an intent problem.
Two pages using similar keywords is not always a problem. It becomes a problem when they are trying to satisfy the same search intent and Google cannot see which page is the strongest answer.
Signals to look for.
- Several URLs ranking for the same query
- Ranking URLs switching frequently
- Pages with very similar headings and copy
- Internal links split between competing URLs
- Several weak pages where one strong page would work better
How to decide what to do.
Once you find overlap, choose whether to keep the pages separate, improve one page, consolidate several pages, or reposition them around different intents.
This decision fits naturally into a wider content strategy or content audit.
A quick example.
A site might have separate pages for “technical SEO audit”, “SEO audit checklist” and “technical website audit” that all say similar things. If they are targeting the same audience and search intent, one stronger page may perform better than three weaker ones.
Practical checklist
- Export queries and landing pages from GSC
- Look for repeated URLs against the same query
- Compare intent and page purpose
- Review internal links and anchor text
- Choose improve, consolidate or reposition
- Redirect carefully if pages are removed
Common mistakes
- Assuming every shared keyword is cannibalisation
- Consolidating pages with different intent
- Ignoring internal links
- Deleting pages without redirects
- Not tracking impact afterwards

FAQ
Is keyword cannibalisation always bad?
No. It only matters when pages compete for the same intent in a way that weakens performance or confuses page purpose.
How do you fix cannibalisation?
Usually by improving one main page, consolidating overlap, changing internal links or repositioning pages around clearer intents.
