Keyword Density Checker

What is this tool?

A text-analysis tool for checking keyword usage. Paste in an article or page copy, and it counts word and phrase frequency, showing density percentages so you can spot over- or under-used terms.

When to use it

  • Checking whether a target keyword appears often enough in an article
  • Spotting accidental keyword stuffing before publishing
  • Seeing which phrases naturally repeat in a long piece of writing
  • Comparing keyword density against a target percentage for SEO
  • Auditing existing page copy for word-frequency patterns

How to use it

  1. 1Paste your text into the input box
  2. 2Review the single-word, 2-word and 3-word phrase frequency lists
  3. 3Check each term's density percentage against the text length
  4. 4Adjust your copy if a term is over-repeated
  5. 5Re-paste the edited text to confirm the new density

Frequently asked questions

What counts as "over-optimized" density?

There's no universal rule, but density climbing much past 2–3% for a single phrase is generally a sign of unnatural repetition.

Does it ignore common words like "the" and "and"?

The single-word list surfaces the most frequent terms as-is; scanning past common stopwords to the meaningful repeated terms is part of reading the results.

Can I analyze an entire article at once?

Yes — there's no practical length limit, though very long text takes a moment longer to process.

Is my text sent anywhere?

No — analysis runs entirely in your browser.
