What Is Keyword Cannibalization?
Keyword cannibalization happens when two or more pages on the same website target the same keyword, causing them to compete against each other in search results instead of one page clearly winning.
By Daud Lawrence, Founder & Semantic SEO Lead
Two of your own pages, competing against each other for the same search — and both losing because of it. Rather than helping, this usually hurts both pages: Google has to guess which one is the better answer, frequently splits ranking signals between them, and often ends up ranking neither as well as a single, consolidated page would rank alone.
Why It’s More Common Than Most Site Owners Realize
Cannibalization tends to build up gradually rather than happen all at once — a blog post written eighteen months ago on a topic, followed by a newer, better page on the same subject added without anyone checking whether the old one still targets the same term. Neither page was written to compete with the other; it happens by accumulation, which is exactly why it’s easy to miss without deliberately checking for it.
How to Spot It in Search Console
Open the Performance report, filter by a specific query you care about, and look at which URLs from your own site are receiving impressions for it. If more than one of your own pages shows up for the same query, that’s cannibalization in progress — Google is genuinely unsure which page should be the answer, and is showing both inconsistently rather than committing to either.
Fixing It — Consolidate, Don’t Just Diversify
The instinct to “make the pages more different from each other” is usually the wrong fix, because it treats the symptom rather than the cause. The more reliable fix is consolidation: identify which page is stronger (more backlinks, better engagement, more complete content), merge the useful content from the weaker page into it, and 301 redirect the weaker page to the stronger one. This concentrates the ranking signal on a single page instead of splitting it.
Frequently Asked Questions
No — pages covering the same broad topic from genuinely different angles or search intents (a service page vs. an educational guide, for instance) aren’t cannibalizing each other if they’re not competing for the same specific query. The Search Console check above is what distinguishes genuine overlap from healthy topical breadth.
No — it happens just as often between a service page and a blog post, or between two service pages with overlapping descriptions, as it does between two articles.
Often a few weeks once Google has recrawled the redirect and consolidated signals onto the surviving page, though competitive terms can take longer to fully settle into a new position.
