Keyword density refers to how often a target keyword appears on a page compared to the total word count, expressed as a percentage. While it was once a major ranking factor, modern search engines focus more on context, intent, and content quality than on strict percentages.
There is no fixed “ideal” keyword density today. However, a natural range of approximately 0.5% to 2% is generally safe and effective for most pages.
Modern SEO evaluates relevance using multiple signals:

Place the main keyword in:
Use variations and related terms instead of repeating the exact phrase.
Write for humans first, search engines second.

Anything beyond that should be justified by context, not optimization goals.
Do not optimize for a number. Optimize for clarity, usefulness, and intent. If the keyword fits naturally, your density is already correct.
