Keyword Cannibalization and Effective Strategies for Keywords Clustering Optimization

Keyword cannibalization occurs when an excessive number of pages on a website target the same or very similar keywords. Traditionally, it has been thought that this situation can lead to several pages competing against each other in search engine rankings, potentially diluting the effectiveness of your SEO efforts. However, the impact of possible keyword cannibalization is not clear and is constantly evolving:

However, it is a fact, that search engines do rank a specific Keywords to multiple pages from a single website. In some cases a single Keyword can be associated with thousands and often more pages in larger and high authority websites.

Ideally, a website should adopt a topic clustering strategy. Each subtopic should have a dedicated page that covers the specific aspect of the primary Keyword (e.g cleaning services), while a sub topic Keywords (Secondary Keywords) may be fro example "house cleaning services" . This structure not only helps avoid keyword cannibalization but also enhances the user experience by providing detailed, relevant information for different search intents.

Keywords Topic/Clustering Strategy

1. Context and Relevance: Modern search engines, particularly Google, are sophisticated in understanding context and relevance, allowing them to recognize different intents even when similar keywords are used across multiple pages.
2. Authority and Depth: Authoritative websites can benefit from targeting variations of a keyword across multiple pages, covering a topic comprehensively and enhancing overall site relevance.
3. High-Ranking Websites: Many high-ranking websites have multiple pages targeting the same or similar keywords, supported by distinct content differentiation.

John Mueller (Google): Mueller has indicated that while multiple pages targeting the same keyword isn't inherently bad, each page should offer unique value.

Optimizing a Whole Website for Many Keywords

When optimizing a large website, it's essential to adopt a strategic approach to keyword usage. Let's explore two scenarios:

1. Duplicate Keyword Usage: If a website with 1000 webpages has the keyword "cleaning services" appearing in the content and meta-tags of 300 pages, this can be problematic for SEO. This approach can dilute authority, confuse search engines, and waste resources.

2. Keyword Topic Clusters: Alternatively, using a keyword topic cluster strategy can be highly beneficial. This involves grouping related keywords around a central theme. For example, "cleaning services" can have related keywords such as:

   • Cleaning services nearby
   • House cleaning services
   • Home cleaning services nearby
   • Office cleaning services
   • Mold cleaning services
   • Restaurant cleaning services
   • Floor cleaning services
   • Carpet cleaning services
   • Bathroom cleaning services

Benefits of Keyword Topic Clusters

• Improved Relevance: Each page targets a specific subtopic, making it more relevant to specific queries.
• Enhanced Authority: Covering a wide range of related keywords establishes your site as an authority in the cleaning services niche.
• Better User Experience: Users find more precise information, leading to higher engagement and satisfaction.
• Efficient Crawl Budget: Search engines can more efficiently index your site, understanding the clear structure and hierarchy of content.

Examples of Effective Keyword Clustering

Scenario 1: Cleaning Services

• Main Keyword: Cleaning services
  
  • Subtopic 1: Cleaning services nearby
  • Subtopic 2: House cleaning services
  • Subtopic 3: Home cleaning services nearby
  • Subtopic 4: Office cleaning services
  • Subtopic 5: Mold cleaning services
  • Subtopic 6: Restaurant cleaning services
  • Subtopic 7: Floor cleaning services
  • Subtopic 8: Carpet cleaning services
  • Subtopic 9: Bathroom cleaning services

Each subtopic (Secondary Keyword) should ideally have a dedicated page that covers the specific aspect of cleaning services. This structure not only helps avoid keyword cannibalization but also enhances the user experience by providing detailed, relevant information for different search intents.
