What Is Keyword Cannibalization?

Keyword cannibalization occurs when multiple pages on your website target the same keyword or closely related search intent. This causes your content to compete against itself in Google’s search results.

Many website owners mistakenly think that targeting the same keyword across multiple articles helps increase their chances of ranking. In reality, it confuses search engines about which page to prioritize, often lowering the rank of all pages involved.

Example of Keyword Cannibalization

Imagine you publish these three blog posts:

• /seo-tools-2025
• /best-free-seo-tools
• /top-10-seo-tools

All three attempt to rank for the keyword “best SEO tools.” Google will struggle to identify the most relevant page, which can result in none of them ranking well. This is keyword cannibalization.

Why Keyword Cannibalization Is Bad for SEO

How to Identify Keyword Cannibalization

Manual Method (No Tools)

1. Create a Keyword-URL Mapping Sheet
   Use a spreadsheet to track each target keyword and the URL assigned to it.
2. Google Search Using Site Operator
   Type site:yourdomain.com "target keyword" into Google.
   For example:
   site:creativeagency24.com "ai tools for social media"
3. Analyze the Results
   If more than one URL appears for the same keyword, there may be keyword cannibalization.

Using Free Tools

Google Search Console (GSC)

• Navigate to Performance > Search Results > Queries
• Click on a specific keyword
• If multiple URLs are receiving impressions for that keyword, this is a sign of cannibalization

Google Analytics

• Review landing page traffic for the same query
• If different pages are attracting visitors via the same search term, investigate further

Using Paid SEO Tools

Semrush

• Navigate to Position Tracking
• Use the Cannibalization Report to find duplicated keyword targets

Ahrefs

• Use Site Explorer > Organic Keywords
• Filter by keyword and check if multiple URLs are ranking for the same term

How to Fix Keyword Cannibalization

There are several ways which you can adopt to fix this issue:

Step 1: Identify the Primary Page

Select the strongest performing page based on:

• Organic traffic
• Number of backlinks
• Content quality
• Alignment with search intent

Step 2: Resolve Conflicting Pages

Step 3: Optimize the Main Page

• Use semantic and related keywords
• Improve on-page SEO (clear H2s, bullet points, internal links)
• Add structured data (FAQ schema)
• Ensure fast loading time and mobile responsiveness

Step 4: Update Internal Linking

• Link all related pages to the main page using varied anchor text
• Avoid linking to outdated or redirected pages

Best Practices to Avoid Keyword Cannibalization

1. Create a Keyword Mapping Strategy

Before writing any new content, assign one main keyword to one specific URL. Use tools like Google Sheets or Notion to log your keyword-to-URL map.

2. Use Semantic Keywords and Variants

Instead of writing three blogs targeting “best SEO tools,” “top SEO tools,” and “free SEO tools,” combine them into one comprehensive guide and use related terms throughout the content.

3. Structure Content into Clusters

Use a content hub strategy where one pillar page links to multiple supporting pages that target subtopics. For example, a main page on SEO tools can link to supporting guides like AI SEO tools, local SEO tools, and technical SEO tools.

4. Perform Regular Content Audits

Use Google Search Console, Ahrefs, or Semrush monthly to monitor which pages are ranking for your top queries and adjust if overlaps occur.

Common Mistakes to Avoid

• Publishing similar blogs on the same topic without differentiating intent
• Ignoring internal linking opportunities
• Using duplicate meta titles or headings across pages
• Forgetting to check old content before creating new posts
