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)
  • Case-insensitive matching

How it works

  1. Paste your article, landing page copy, or blog post.
  2. Optionally enter the keyword or phrase you're targeting.
  3. Review the density percentage and top-10 word frequencies.
  4. 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.
