What keyword density measures
Keyword density is the percentage of words on a page that are a given keyword: (keyword occurrences / total words) × 100. A density checker counts single words and multi-word phrases (n-grams) so you can see which terms dominate your copy.
It's a useful diagnostic — it shows whether you've actually mentioned your topic or drifted off it — but modern search engines do not rank by hitting a magic density number. Chasing a target percentage is a dated tactic.
How to use it well
- Use it to confirm your primary topic appears naturally in the title, intro, headings and body.
- Look for related terms and synonyms, not just the exact keyword — search engines reward topical coverage over repetition.
- Compare against the intent: if you're targeting "running shoes" but "shoes" dominates and "running" barely appears, tighten the copy.
- Treat anything above ~2–3% for one phrase as a signal to rewrite for readability, not a hard rule.
Common mistakes
- Keyword stuffing to hit a percentage — this reads badly and can look manipulative.
- Optimizing for one exact phrase while ignoring the broader topic.
- Assuming a specific density (e.g. "1.5%") is required — there is no such threshold.
- Counting stop words ("the", "and") and drawing conclusions from the noise.
Bottom line: write naturally for the reader, then use density as a sanity check, not a target.

Frequently asked questions
What is a good keyword density?
There is no magic number, but roughly 1–2% for a primary keyword reads naturally. Anything much higher risks looking like keyword stuffing, which can hurt rankings. Write for people first.
