What is a Keyword Density Checker?

A keyword density checker is a free online tool that analyzes how often specific words or phrases appear in your content. It shows each keyword's count, frequency, and percentage of the total text so you can optimize your writing for search engines without keyword stuffing.

How to use it

Paste or type your content into the text area, set a minimum word length to filter out short filler words, choose how many top keywords to show, and click Analyze.

  • Review the total and unique word counts for an overview of your content size.
  • Check each keyword's count and density percentage in the results table.
  • Aim for a density of 1% to 3% for your main keywords.

Tips for better SEO

Use your primary keyword in the title, headings, and first paragraph, then repeat it naturally throughout the body. Use this tool to verify you are not overusing it.

  • Target a density of 1% to 3% for primary keywords.
  • Use related synonyms and long-tail variants for secondary keywords.
  • Keep the writing natural for readers first, search engines second.
