How to Find and Fix Keyword Cannibalization (The Right Way)
Keyword cannibalization is one of those SEO problems that sounds scary but is actually fixable once you have the right data.
The problem: you have two (or more) pages that Google treats as competing for the same query. Instead of one strong result, you get two weak ones.
Why it happens
Usually one of these:
- You wrote a blog post and a services page that both target "SEO audit"
- Your site grew organically and nobody was tracking what keywords each page owned
- A site migration created duplicate URL structures
How to diagnose it properly
The naive approach — searching Google for your keywords and seeing which page ranks — doesn't scale. With 500+ keywords, you need data.
Step 1: Export your Search Analytics data from GSC (Performance → Export → CSV).
Step 2: For each query, find which pages are getting impressions. If two pages show up for the same query in the top 10, you have a conflict.
Step 3: Measure impact. Not all cannibalization is worth fixing. A conflict where both pages get 2 clicks/month is not urgent. A conflict where a weak page is outranking a strong one for a 500-click/month query is a fire drill.
The fix
Three options, in order of preference:
Option A: Redirect. If one page is clearly stronger and the other adds no unique value, redirect the weaker one. Simple, permanent, Google-friendly.
Option B: Consolidate. If both pages have good content, merge them. Keep the stronger URL, redirect the weaker one, incorporate the best content from both.
Option C: Differentiate. If both pages serve genuinely different intents (one informational, one transactional), rewrite them to be clearly distinct. Make sure internal links reinforce which page targets which intent.
