Free Keyword Density Checker
Keyword stuffing penalties are real — but so is under-optimization. NToolHub's free Keyword Density Checker counts exact occurrences of your focus keyword and calculates its true density percentage, with clear verdicts for too-low, healthy and stuffing-risk levels. Content writers use it as the final polish pass on every article.
How to Use the Keyword Density Checker
- Enter your focus keyword — the term you want the page to rank for.
- Paste the article or page text and click Analyze.
- Check the density %: 0.5–2.5% is a healthy, natural range.
- If it’s too high, rewrite with synonyms; if too low, weave the keyword in naturally.
Features
Enter any focus keyword (multi-word phrases supported with exact phrase matching), paste your text, and get occurrence count, total words and density to two decimal places — plus smart verdicts calibrated to the widely recommended 0.5–2.5% range.
Benefits & Use Cases
The right density keeps pages topically focused without tripping spam filters. Checking before publishing catches both thin optimization (keyword never appears) and stuffing (reads like a robot wrote it) while editing is still cheap.
Tips
Aim for 0.5–2.5% density, place the keyword in the title, first paragraph and one subheading, then write naturally with synonyms and related terms — modern Google understands topical coverage, not just repetition.
Frequently Asked Questions
What is a good keyword density?
Most SEOs consider 0.5–2.5% healthy — enough to establish topical focus without looking stuffed. There's no official Google target; natural writing matters more.
Can keyword density get me penalized?
Extreme repetition (5%+) can trigger spam filters and always reads terribly to humans. Moderate, natural usage is completely safe.
Does the tool match multi-word phrases?
Yes — it counts exact phrase occurrences (word-boundary, case-insensitive), so 'keyword density checker' matches as one unit, not three separate words.
Should I count keywords in headings separately?
The tool analyzes full pasted text. For best results, paste the complete article including headings — that's what Google evaluates.
