Keyword density is the percentage of times a target keyword appears within a piece of content relative to the total word count, once used as a primary on-page optimization metric in early SEO practice.
Modern search engines rely far more heavily on semantic understanding and topical relevance than on rigid keyword density formulas, meaning artificially repeating a keyword to hit a specific percentage generally provides little benefit and can actively harm readability.
Rather than targeting a specific keyword density figure, content should use a target keyword and its natural variations wherever it genuinely fits the writing, prioritizing clarity and comprehensiveness over mechanical repetition.
