Keyword Cannibalization
Plain-language definitionA situation where multiple pages compete for the same search intent without offering distinct value. The result can be diluted relevance and unstable rankings.
Why it matters
Use the term to make a better decision.
In practice, keyword cannibalization matters when a team needs to connect a technical or creative choice to a visible change in clarity, performance, discovery, or conversion. The useful question is not whether the term sounds sophisticated. It is what decision it helps the team make.
