About the Keyword Density Checker
Keyword density is the percentage of a page's total words that match a target keyword or phrase. It was a primary SEO ranking signal in the 2000s; today it's a sanity check against both under-optimization and keyword stuffing. This tool counts exact-match and multi-word phrase occurrences, reports density, and surfaces the top terms already present so you can see whether your content naturally reinforces your target topic.
Features
- Automatic top-10 keyword extraction
- Targeted keyword density calculation
- Multi-word phrase support with proper escaping
- Recommended-density guidance (1–3% sweet spot)

How it works
- Paste your article, landing page copy, or blog post.
- Optionally enter the keyword or phrase you're targeting.
- Review the density percentage and top-10 word frequencies.
- Adjust copy to land in the 1–3% range without stuffing.
Frequently asked questions
What's a healthy keyword density?
+
1–3% is the widely-cited range. Below 1% your keyword is under-represented; above 3% risks being flagged as keyword stuffing by Google.
Does Google still care about keyword density?
+
Not directly — but it correlates with topical relevance. Modern SEO is about topic authority via related entities, not exact-match repetition.
Can I check multi-word phrases?
+
Yes. Enter 'data engineering jobs' as a single target and we'll count full-phrase occurrences.
Does capitalization matter?
+
No. Matching is case-insensitive, so 'SEO' and 'seo' are counted together.
Are stop words excluded?
+
The top-10 list filters common stop words (the, a, is, etc.). Targeted keyword counts do not.
