Keyword Density Checker

Analyze word, two-word and three-word phrase frequency directly in your browser.

Analyze word and phrase frequency

Paste text to inspect total words, unique words, reading time and common one-, two- and three-word phrases.

What keyword density means

In this tool, single-word density is simply the number of times a term appears divided by the total detected word count. It is a descriptive statistic—not a target score and not a promise of search performance.

How to use the analysis

  1. Paste the text you want to inspect.
  2. Choose whether common English stop words should be omitted from the single-word frequency table.
  3. Review recurring words and phrases for accidental repetition, topic consistency and editing opportunities.
  4. Rewrite for clarity when repetition sounds unnatural; do not force a percentage.

Phrase frequency can reveal content patterns

Two- and three-word phrases often reveal repeated product names, locations, claims or sentence patterns more clearly than individual words. That makes phrase frequency useful for quality control, editorial review and detecting boilerplate.

Why there is no “ideal density” score

Search relevance depends on far more than repeating a term. This tool avoids labeling a density percentage as “good” or “bad” because that would turn a neutral text statistic into a misleading optimization rule.

Is there an ideal SEO keyword density?
This tool does not claim an ideal percentage. Use frequency as an editing signal, not a ranking formula.
What are stop words?
They are very common words such as the, and, or, and to that can dominate frequency tables without describing the main topic.
Is my pasted text uploaded?
No. Analysis in this version runs locally in your browser.
