# Keyword Cannibalization Checker: Common Mistakes and Best Practices

Most problems with keyword Cannibalization Checker aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Publishing near-duplicate posts targeting the same keyword because different team members didn't check what already existed.

Mistake 2: Assuming more pages on a topic always helps — beyond a point, splitting one strong topic across several thin pages actively hurts all of them.

Mistake 3: Fixing cannibalization by deleting a page outright instead of redirecting it, which throws away any backlinks and history it had accumulated.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Check Search Console's Performance report filtered by query — multiple URLs from your own site appearing for the same query is the clearest sign of cannibalization.
- Audit for cannibalization after any large content push — it's easy for a new post to unintentionally overlap with something written months earlier.

Worth reading alongside this: our guide to search intent, which covers the adjacent side of the same part of a technical SEO audit.

Keyword Cannibalization Checker catches most of this automatically, which is the easiest way to stop these mistakes from shipping in the first place.
