Keyword cannibalization happens when two or more pages on the same website target the same or very similar keyword, causing them to compete against each other in search results rather than reinforcing a single page’s ranking strength. Instead of one strong page climbing steadily up the results, a search engine may struggle to decide which of the competing pages is most relevant, and rankings for both can end up weaker and less stable as a result. Fixing it usually involves consolidating the competing pages into one authoritative piece or clearly differentiating each page’s target keyword and intent so they stop overlapping.
A blog that publishes five separate posts all targeting “best running shoes” is a classic case of keyword cannibalization, splitting its ranking potential across pages instead of concentrating it on one strong article.
An e-commerce site might unintentionally create this same problem by having both a category page and a blog post competing for the same term like “waterproof hiking boots.”
SEO audits often uncover this issue on older websites, where years of content added without a clear plan have left dozens of pages quietly competing against each other in search results.
