“Keyword cannibalization sounds made up – is it actually a thing in SEO?”
Short Answer: It’s real – but not always harmful. Let’s unpack when keyword cannibalization matters, how to spot it, and how to fix it strategically.
🧐 What Is Keyword Cannibalization?
Keyword cannibalization happens when multiple pages on your website target and rank for the same (or very similar) keywords. These pages essentially compete with each other in the search engine results pages (SERPs).
🚨 When Keyword Cannibalization Is a Real Problem
When it genuinely causes SEO issues, it can lead to:
- 🔻 Diluted Authority: Instead of one strong page ranking highly, link equity and authority are spread thin across multiple weaker pages.
- 🤖 Confused Search Engines: Google may struggle to determine which page is most relevant for the query, causing:
- Ranking instability: Different pages may swap in and out of the SERPs unpredictably.
- Wrong page ranking: A lower-converting or less optimized page might rank over the one you actually want seen.
- 🔄 Wasted Crawl Budget: Google might keep crawling redundant pages instead of indexing newer or higher-value content.
- 🙄 Confused Users: Visitors might land on a less relevant page, resulting in higher bounce rates and poor UX.
- 📉 Lower Conversion Rates: If the page that ranks isn’t the one optimized for conversions, your ROI suffers.
✅ When Keyword Cannibalization Isn’t a Problem
Sometimes what looks like cannibalization is actually a sign of SEO health:
- 📚 Topical Authority: Covering a topic in-depth with multiple pages can help demonstrate expertise. Each page might rank for different long-tail keywords.
- 🔍 Different User Intent: Similar keywords don’t always mean the same search intent.
- Example:
- “Best hiking boots” = product comparison
- “How to clean hiking boots” = informational guide
- Example:
- 🌐 SERP Diversity: Google sometimes intentionally shows multiple results from the same site when it finds them helpful. That’s not cannibalization – it’s authority.
- 🔁 Natural Keyword Overlap: Some overlap is inevitable, especially with broad topics. It’s not necessarily bad.
- ⚠️ Misdiagnosed Issues: Thin content, weak internal linking, or overall ranking volatility may look like cannibalization, but have different root causes.

🛠 How to Identify Keyword Cannibalization
Use Google Search Console:
- Navigate to Performance → Queries
- Click on a suspected keyword → Then check the Pages tab
- If multiple URLs consistently rank for the same keyword, that’s a sign
Use SEO Tools:
- Platforms like Ahrefs, Semrush, Moz offer keyword cannibalization reports
- Track multiple URLs ranking for the same keyword over time
Check Site Search:
- Are users getting confused by similar internal pages? This can indicate overlap issues
🧩 How to Fix True Cannibalization
If you confirm actual cannibalization, here’s how to resolve it:
- 📝 Merge Content: Combine similar pages into one high-authority page, then use 301 redirects
- 🏷 Use Canonical Tags: If you have duplicate or very similar pages, add a
rel="canonical"tag to the less preferred version, pointing to the one you want Google to index and rank. This helps consolidate SEO signals like backlinks and prevents confusion about which page should appear in search results.
🔍 Example:
If you have/seo-guideand/seo-guide-2024with similar content, place this canonical tag in the<head>section of/seo-guide-2024:
html<link rel="canonical" href="https://www.example.com/seo-guide" />
This tells search engines that/seo-guideis the preferred (canonical) version to rank. - 🔗 Improve Internal Linking: Ensure all internal links point to your preferred page
- 🎯 Differentiate Content: Adjust the intent, target different long-tail keywords, or expand topics to make each page distinct
- 🚫 Noindex Low-Value Pages: If a page isn’t worth merging and doesn’t add value, add a noindex tag
- ➡️ Use 301 Redirects: When deprecating old content in favor of better versions
📌 Conclusion: Don’t Panic – Plan Strategically
Keyword cannibalization isn’t a fake concept, but it’s often misunderstood. Most websites have some level of keyword overlap – and that’s OK if:
- Each page targets a different intent
- Pages are high quality and unique
- Your internal linking makes priority pages clear
- Your site builds topical authority across related topics
