What this tool does

Analyze word frequency in a block of text to spot accidental repetition, missing topic language and overused terms. The result is descriptive, not an SEO score.

Modern search optimization is not about forcing a keyword to reach a target percentage. Repetition can make writing awkward and may reduce usefulness. Use this analyzer as an editing lens: identify dominant vocabulary, then read the text naturally and decide whether repeated words are necessary or whether clearer alternatives would help.

Useful for

  • Review drafts for accidental overuse of the same words.
  • Compare the vocabulary of two versions of a page.
  • Find common terms in survey responses, notes or content outlines.

How to use it

  1. Paste the text you want to analyze.
  2. Choose one-word, two-word or three-word phrases.
  3. Review frequency counts and percentages.
  4. Edit the source text based on readability and meaning, not a fixed density target.

Practical tips

  • Exclude very common stop words when you want to focus on topic language.
  • A high percentage is not automatically bad if the word is genuinely necessary.
  • Do not add awkward synonyms just to manipulate the numbers.
  • Read the finished text aloud after editing to check natural flow.

Frequently asked questions

What keyword density should I target?

There is no universal percentage that guarantees rankings. Focus on complete, helpful coverage of the topic and natural language.

Does the tool send my draft to a server?

No. Analysis is performed in your browser.

Can I analyze phrases instead of single words?

Yes. The tool can count one-, two- or three-word sequences to reveal repeated phrases.
