What is Keyword Cannibalization?
Keyword cannibalization occurs when multiple pages on a website compete for the same keywords or serve the same purpose, harming each other’s search engine rankings. This happens when several pages target the same or very similar search queries, making it difficult for search engines to determine which page is the most relevant result.
How It Works
Concept and Function:
Keyword cannibalization arises when a website has multiple pages optimized for the same or similar keywords. This can occur due to publishing similar content over time, creating new versions of pages without redirecting the old ones, or optimizing different pages for the same keyword.
When multiple pages target the same keyword, search engines struggle to identify which page is the most authoritative and relevant for the search query. This leads to internal competition among the pages, resulting in lower rankings and diluted authority signals such as backlinks and CTR.
Practical Use Cases:
For example, if a website has two articles, one titled “Does readability rank?” and another titled “Readability ranking factor,” both optimized for similar keywords, Google may find it hard to determine which article is more important. This can lead to both articles ranking lower than they would if only one was optimized for the keyword.
Another example is when a website has category pages (e.g., “laptops” and “gaming laptops”) that both target the same keyword, causing confusion for search engines about which page to rank higher.
Why It Matters
Importance in SEO:
Keyword cannibalization negatively impacts a website’s SEO performance by reducing search visibility and organic traffic. When multiple pages compete for the same keyword, it becomes challenging for search engines to rank any of the pages highly, leading to lower rankings and decreased organic traffic.
It also dilutes the authority signals such as backlinks, content quality, and user experience, which are crucial for ranking well in search results. Instead of having one highly authoritative page, the website ends up with several low-authority pages.
Impact on Website Performance and User Experience:
Keyword cannibalization can frustrate users by presenting them with similar information or duplicate content across multiple pages. This can lead to a poor user experience and lower engagement rates.
It also results in wasted resources, as time and effort spent on creating competing content could be better directed towards other SEO initiatives.
Best Practices
Identifying Keyword Cannibalization:
To recognize keyword cannibalization, perform a search for your site using the keyword you suspect might have multiple results (e.g., site:yourdomain.com "keyword"). Check which pages are ranking and their positions. If multiple pages are ranking low for the same keyword, it indicates cannibalization.
Auditing and Analyzing Content:
Conduct a comprehensive website audit to identify and address all cannibalizing pages. Use tools like Semrush or other SEO analytics platforms to track the performance of your pages and identify which ones are competing for the same keywords.
Solutions to Fix Keyword Cannibalization:
Consolidate Content:
Merge multiple pages into one comprehensive page. Choose the best-performing page and revamp it to include all relevant content. Use 301 redirects for the merged pages to maintain SEO value.
Canonicalization:
If you need to keep similar pages, use canonical tags to indicate the preferred page for search engines.
Optimize Links and Content:
Ensure that the most relevant page is well-linked internally and has optimized meta titles and descriptions. De-optimize other pages for the same keyword to avoid competition.
Improve Internal Linking:
Direct users and search engines to the preferred page by building internal links from cannibal pages to the primary page using relevant anchor text.
Prevention:
Regularly track and monitor keywords to avoid optimizing multiple pages for the same search query. Ensure that each page has a clear and unique purpose and targets different keywords or search intents.
By following these best practices, you can effectively identify, fix, and prevent keyword cannibalization, improving your website’s SEO performance and user experience.
