Keyword Cannibalization

What is Keyword Cannibalization?

Definition: Keyword cannibalization occurs when multiple pages of the same website compete against each other in search engine results due to targeting similar or identical keywords. This internal competition can dilute the website’s authority on the topic, potentially lowering the ranking of both pages and confusing search engines about which page to prioritize for a given query.

Types of Keyword Cannibalization

  1. Content-Level Cannibalization: Occurs when two or more content pieces (blog posts, articles, product pages) target the same keywords without a clear differentiation in intent or topic.
  2. Structural Cannibalization: Arises from site architecture issues, where URL structures or internal linking strategies cause search engines to struggle in distinguishing between pages of similar content or purpose.
  3. Semantic Cannibalization: Happens when pages target keywords that are semantically related too closely, leading to overlap in search engine rankings even if the topics might be slightly different.


  1. E-commerce Websites: An online store might have separate product pages for items that are very similar, with each page targeting the same search terms, leading to cannibalization.
  2. Blog Platforms: A blog that publishes multiple articles on similar topics without a clear strategy can end up having those articles compete against each other for rankings on the same keywords.
  3. Service Pages: A company offering services in closely related fields may create individual pages for each service that inadvertently compete for the same keywords.

Technical Details

  • Identifying Cannibalization: Use SEO tools to identify instances where multiple pages rank for the same keywords, especially if those rankings are low or fluctuating.
  • Solutions: Strategies to resolve keyword cannibalization include consolidating content (merging similar pages), differentiating content to target unique aspects of a keyword or topic, improving internal linking to designate one page as the authority, and using 301 redirects to consolidate page authority.
  • Prevention: A clear keyword strategy that assigns specific topics or queries to distinct pages can prevent cannibalization. Regular audits of site content and structure also help in identifying potential issues early.


Keyword cannibalization is a significant SEO issue that can undermine a website’s performance in search engine results. Identifying and addressing instances of cannibalization through strategic content consolidation, differentiation, and site architecture optimization are essential steps in maintaining and improving a site’s search engine visibility and user experience.
