*This article was last updated on 18/10/2023

Effectively managing keywords is paramount to achieving online success. However, amidst the intricacies of keyword strategy lies a potential pitfall known as keyword cannibalization. Often overlooked or misunderstood, this phenomenon can seriously impact your SERP rankings.

Understanding the theory behind keyword cannibalization and its implications allows you to adopt effective strategies and tools. Through proactive keyword management, websites can regain authority, enhance user experience, and reclaim their ranking positions.

What is Keyword Cannibalization?

Keyword Cannibalization

Keyword cannibalization is a phenomenon that occurs when multiple pages within a website unintentionally target the same keyword or set of keywords. It is a situation where different pages compete against each other in SERP ranking rather than working together.

This unintentional overlap can lead to confusion for search engines, diluted ranking signals, and diminished organic traffic and visibility.

How Keyword Cannibalization Affects Your SEO

Keyword cannibalization confuses search engines and users alike. Search engines will find it challenging to determine the most relevant page to display in SERPs. After all, they will face multiple pages trying to describe the same or similar things.

The results of keyword cannibalization will vary, but none of the outcomes is good. Some examples include;

Dilution of Ranking Authority

Keyword cannibalization dilutes the ranking authority that could have been concentrated on a single page. Instead of consolidating ranking signals, multiple pages competing for the same keyword fragment the authority and weaken the overall SEO efforts.

Incorrectly Ranked Pages

When multiple pages target the same keyword, search engines may have difficulty determining the most relevant page to display in search results. This confusion can lead to lower rankings and reduced visibility. 

Decreased Click-Through Rates

Keyword cannibalization can negatively affect click-through rates. When multiple pages appear in search results for the same keyword, users may need guidance on which page to choose, leading to lower CTRs for each page.

Poor User Experience and Engagement

Keyword cannibalization can result in a poor user experience. Users may encounter duplicated or similar content across different pages, which can be frustrating and confusing. This can lead to decreased engagement, higher bounce rates, and lower conversions.

Causes of Keyword Cannibalization

Keyword cannibalization can occur due to various factors, from inadequate keyword planning to implementation. Understanding the causes of this phenomenon is crucial to effectively identifying and addressing keyword cannibalization within a website.

Some likely causes include;

Lack of a Proper Keyword Strategy

A significant cause of cannibalization is the absence of a well-defined keyword strategy. Without a clear plan, different pages within a website may unintentionally target the same keywords. 

This lack of coordination can lead to internal competition, as these pages compete for search engine rankings without contributing to the overall relevance and authority of the website. A comprehensive keyword strategy is essential to avoid keyword cannibalization.

Unoptimized Internal Linking

Another contributing factor to keyword cannibalization is unoptimized internal linking. Internal links serve as a navigational pathway for search engine crawlers, helping them understand the website’s structure and the relationships between its pages. 

When multiple pages have similar or identical anchor text pointing to them, it becomes challenging for search engines to determine the most relevant page. As a result, ranking signals and authority get diluted among competing pages.

Content Duplication

Content duplication, whether intentional or unintentional, can lead to keyword cannibalization. When multiple pages contain similar or identical content, search engines face difficulty determining which page should be ranked for a particular keyword. 

This can result in search engines choosing a page that could be better or more relevant. The result will be lower rankings and reduced organic visibility. Content duplication can occur due to poor content management practices, syndication, or even your system for content generation.

Inconsistent or Uncoordinated On-Page Optimization

Inconsistent or uncoordinated on-page optimization practices can contribute to keyword cannibalization. Each page on a website should be optimized for specific target keywords to signal its relevance to search engines. 

However, what happens if different pages within the website have inconsistent or conflicting on-page optimization elements? For example, title tags, meta descriptions, heading tags, and keyword usage.

Lack of Regular Content Audits and Updates

As websites evolve and grow, new content is added, and existing content may need to be updated or updated. Over time, this can create situations where multiple pages unintentionally target the same keywords or cover similar topics. 

Without periodic content audits to identify and address such instances, keyword cannibalization can persist, hindering the overall SEO performance of the website. New websites will have few issues, but what happens if you need to manage thousands of posts and pages?

How to Prevent and Resolve Keyword Cannibalization

Preventing and resolving keyword cannibalization is crucial to maintain a strong and cohesive SEO strategy. 

By implementing the following strategies and best practices, you can mitigate risk and optimize keyword management:

Conduct Comprehensive Keyword Research and Planning

Keyword research tools such as SEMrush, Ahrefs, and Moz Keyword Explorer are invaluable when identifying potential keyword issues. These tools allow you to analyze keyword search volume, competition, and trends, enabling you to make informed decisions.

  • Conduct thorough keyword research to identify a wide range of relevant keywords for your website.
  • Create a keyword mapping strategy that assigns specific keywords to pages based on relevance and intent.
  • Use keyword research tools to analyze search volume, competition, and user intent to make informed keyword decisions.

Build Clear Content and Page Structures

  • Develop a well-organized content and page structure plan that ensures each page has a unique focus and target keyword(s).
  • Clearly define each page’s purpose and target keywords to avoid overlap and confusion.
  • Create a content hierarchy emphasizing the most critical and strategic pages, avoiding duplication or redundancy.

Optimize Your Internal Linking

  • Implement a coherent internal linking strategy that guides search engine crawlers and users to the most relevant pages.
  • Use descriptive anchor text that reflects the targeted keywords and the linked page’s content.
  • Avoid excessive internal links with the same anchor text pointing to different pages targeting the same keyword.

Conduct Regular Content Audits

SEO auditing tools like Screaming Frog and DeepCrawl can be utilized to crawl your website and identify instances of keyword cannibalization. These tools provide comprehensive reports on duplicate content, page titles, meta descriptions, and other on-page elements.

  • Conduct regular content audits to identify instances of keyword cannibalization and content duplication.
  • Consolidate or reoptimize overlapping content by merging pages, redirecting URLs, or updating content to ensure unique and valuable information.
  • Remove or update outdated or low-quality content that does not align with your keyword strategy.

Use Canonical Tags and 301 Redirects

Implementing canonical tags is a powerful technique for managing keyword cannibalization. Canonical tags indicate the preferred version of a page when duplicate or similar content exists across multiple pages. 

  • Implement canonical tags to indicate the preferred version of a page when duplicate or similar content exists across multiple pages.
  • Set up 301 redirects to consolidate the ranking authority of multiple pages targeting the same keyword into a single preferred page.

Monitor and Analyze Performance

Tracking keyword rankings and monitoring your website’s performance is crucial for detecting keyword cannibalization. Tools like Google Search Console, SEMrush, and Moz provide valuable insights into keyword rankings, organic traffic, and click-through rates. 

By monitoring keyword performance over time, you can identify fluctuations or declines that may indicate keyword cannibalization issues.

  • Regularly monitor your website’s organic rankings, traffic, and user engagement metrics to detect any signs of keyword cannibalization.
  • Utilize SEO analytics tools and platforms to track keyword performance, identify overlaps, and make data-driven decisions.

How NOT to Fix Keyword Cannibalization

While knowing how to address keyword cannibalization effectively is essential, it’s equally crucial to understand what not to do when attempting to fix this issue. Taking the wrong approach can exacerbate the problem or create new complications. 

Here are some common mistakes and ineffective approaches to avoid:

Ignoring the Issue

Neglecting to address keyword cannibalization is a grave mistake. Ignoring the problem won’t prevent it; it will only persist and continue to harm your website’s search engine rankings and visibility. Acknowledging the issue and taking proactive steps to resolve it is essential.

Deleting Pages

Deleting pages that are involved in keyword cannibalization is a straightforward solution. However, this approach can result in the loss of valuable content and disrupt the user experience. It’s important to carefully evaluate the pages in question and determine if there are alternative methods for resolution before resorting to deletion.

Randomly Changing Target Keywords

Changing target keywords arbitrarily requires proper analysis or strategy for an effective solution. Blindly changing keywords can lead to confusion, loss of rankings, and unintentional creation of new keyword cannibalization issues.

Neglecting User Intent

Overlooking user intent when addressing keyword cannibalization can lead to ineffective solutions. Simply merging pages without considering the user’s needs and expectations can result in a bad user experience and negatively impact organic rankings.

Overusing 301 Redirects

Overusing redirects can create a complex web of redirections, potentially impacting user experience, page load times, and search engine crawling efficiency. It’s crucial to use redirects judiciously and consider alternative solutions when appropriate.

Prevent Internal Competition for Better SEO

You can prevent and mitigate the risk of keyword cannibalization by implementing effective strategies and best practices. A comprehensive keyword research and planning process, coupled with clear content and page structure, can help allocate keywords strategically and avoid overlap.

Avoiding common mistakes is equally important. Ignoring the issue, deleting pages without consideration, randomly changing target keywords, and neglecting user intent are ineffective approaches that can worsen the problem.

As the digital landscape evolves, keyword cannibalization will remain a challenge. However, armed with knowledge, tools, and best practices, you can navigate this obstacle and optimize your website’s search engine visibility.
