Enter a keyword or phrase to calculate density.

Density runs in your browser. Nothing you paste is sent to our servers.

How it works

Paste text and enter a keyword or phrase. Live results show total words, how many times the keyword appears, and density as a percentage.

Formula: density = (occurrences ÷ total words) × 100, rounded to 2 decimal places. Matching is case-insensitive. Words use the same Unicode whitespace tokenization as the Word Counter (punctuation attached to a token stays with that word).

Multi-word phrases count non-overlapping consecutive word matches. Density still divides phrase hits by total words (a common SEO heuristic)—not by the number of phrase-length windows.

Empty text shows zeros. An empty keyword prompts you to enter one and does not crash. Use Example for a sample, or Clear to reset. Analysis runs entirely in your browser.

Examples

  • Text “hello world hello”, keyword “hello” → 2 occurrences, 3 words, 66.67% density
  • Text “SEO tools help SEO”, keyword “seo” → 2 occurrences (case-insensitive)
  • Text “keyword density matters for keyword density”, keyword “keyword density” → 2 phrase hits ÷ 6 words = 33.33%
  • Empty text → 0 words, 0 occurrences, 0% density

FAQ

Is my text uploaded to a server?

No. Keyword density runs entirely in your browser. Pasted content is not sent to Nova Engine.

Do I need an account?

No. All published tools work for guests without login.

How is density calculated?

Density = (keyword occurrences ÷ total words) × 100, rounded to 2 decimal places. For phrases, each non-overlapping match counts as one occurrence, still divided by total words.

Is this the same as an SEO-category keyword tool?

This is the Text Analysis tool at /text/keyword-density-checker. A separate SEO-category page may exist later; routes are not merged.

What about stop words or stemming?

This tool does not apply stop-word lists, stemming, or TF-IDF. It counts exact case-insensitive token matches only.
