    Keyword density guide

    Direct answer: Keyword density is the percentage of times a keyword appears compared with total word count. It is useful for auditing, but it should not replace helpful writing.

    Best practices

    Use keyword density to check balance, clarity, and topical focus.

    • Keep primary keyword usage natural.
    • Use synonyms and related phrases.
    • Prioritize intent and readability.
    • Avoid repeating the same exact phrase in every paragraph.

    SEO warning

    High keyword density can make content look spammy and hard to read.

    • Below 0.5% may be too weak for the main keyword.
    • Around 0.5%–2.5% is usually natural.
    • Above 3% deserves manual review.
    • Above 5% is often over-optimized.
