Keyword Cannibalization
Quick Definition
Keyword cannibalization occurs when multiple pages on the same website target the same keyword and compete against each other in search results. It dilutes ranking signals and confuses search engines about which page to rank.
Why It Matters
Keyword cannibalization is a silent traffic killer. When multiple pages compete for the same keyword, Google may rank neither page well. Many sites unknowingly lose rankings because of cannibalization issues that could be fixed by consolidating or differentiating content.
Real-World Example
A marketing blog has three separate posts: "SEO tips for beginners," "beginner SEO guide," and "SEO basics for new marketers." All three target essentially the same keyword and intent. Google rotates between them in search results, and none ranks higher than position 15. By merging all three into one comprehensive guide, the consolidated page could rank in the top 5.
Signal Connection
Relevance -- When multiple pages target the same keyword, you are splitting your relevance signals. Instead of one strong page with concentrated authority, you have multiple weak pages competing against each other and your competitors.
Pro Tip
Search "site:yourdomain.com keyword" in Google to check for cannibalization. If multiple pages from your site appear for the same query, you have cannibalization. In GSC, filter by query and check if multiple pages get impressions for it.
Common Mistake
Beginners think having more pages targeting the same keyword gives them more chances to rank. The opposite is true -- it splits your authority and confuses Google. One comprehensive page almost always outperforms three thin pages targeting the same topic.

Answer: C. Merge the posts into one comprehensive page and redirect the other
The best fix is to merge the competing posts into one comprehensive page and set up a 301 redirect from the removed URL to the consolidated one. This concentrates all ranking signals into a single, stronger page.
