When the Keyword Cannibalization Checker seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Two pages rank alternately
Classic cannibalisation - pick the stronger page, differentiate or merge the other, then redirect.
The tool found no conflicts
Pass every URL you suspect; hidden duplicates can rank beyond the checked set.
Both pages target different intents
Then it is not cannibalisation - refine titles so each page signals its distinct intent.
Merging would lose a good page
Differentiate instead: sharpen each page unique angle, keywords and internal links.
Redirects tanked traffic
Consolidate to the page with links and rankings; keep valuable content from the loser during the merge.
New conflicts keep appearing
Publishing without checking existing coverage causes it - search your target keyword before writing.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Assuming every overlap is harmful
- Ignoring searcher intent differences
- Deleting pages without checking links
- Fixing one keyword while creating another
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Is keyword cannibalisation always bad?
No - intentional pages serving different intents can share a term; the problem is identical intent competing.
How do I fix it fast?
Merge or redirect weaker duplicates into the strongest page, and sharpen what remains.
Does consolidation cause temporary drops?
Sometimes - consolidation consolidates signals, and rankings usually settle stronger afterwards.
Is my data stored?
No - checks run in your browser with nothing saved.
