Keyword density as a strict target (aim for exactly 2%, for instance) is largely outdated guidance; modern search engines use far more sophisticated natural language understanding that reads meaning and topical relevance rather than counting keyword repetitions, and chasing a specific density number can actively produce awkward, keyword-stuffed writing that reads poorly and can be flagged as manipulative. The more current best practice is writing naturally and comprehensively about a topic, using the target keyword and its natural variations, synonyms, and related terms where they genuinely fit, rather than tracking a density percentage at all. Keyword stuffing — the aggressive, unnatural overuse this outdated metric encouraged — is explicitly called out in Google's spam policies.
Example
A writer drops a rigid '2% keyword density' rule in favor of naturally covering a topic's related terms and subtopics, producing more readable content that still ranks for the primary keyword and a wider spread of related queries.
