What does "keyword cannibalization" refer to?

Keyword cannibalization occurs when multiple pages on your website target and rank for the same or very similar keywords. This confuses search engines, making it difficult for them to determine which page is most relevant to a user's query. As a result, your pages might compete against each other, diluting their authority and potentially lowering their rankings for those keywords. The correct option accurately describes this scenario. "Using too many keywords on a single page" refers to keyword stuffing, a different SEO issue. "Keywords that are too competitive to rank for" describes keyword difficulty, not cannibalization. "Removing keywords from old content" is a content optimization strategy, unrelated to this concept.
