How keyword density is calculated

Keyword density is how often a word appears compared with the total number of words: occurrences ÷ total words × 100. If a word appears 12 times in an 800-word article, its density is 12 ÷ 800 × 100 = 1.5%. This tool counts single words (not phrases) after removing stop words such as “the” and “and”, and lists the most frequent ones with their counts, densities and a readability score.

Step by step

  • Add content: paste your text, or enter a URL and click Fetch Content to load a public page.
  • Set the options: language, minimum word length (raise it to ignore short words), the maximum number of keywords to show, and any custom stop words such as your brand name.
  • Analyze: review the top keywords, the recommendations and the readability score.
  • Compare: add several URLs and compare them to see how your page's wording differs from other pages on the same topic.
  • Export: copy the results as JSON or download a report.

How to interpret the numbers

There is no ideal keyword density, and search engines do not use a target percentage. Use the numbers as a sanity check instead:

  • If one word makes up several percent of a page, the text may read as repetitive. Vary the wording.
  • If the topic you are targeting does not appear among your top words, the page may not cover it clearly enough.
  • Compare with strong pages on the same topic to find related terms you have not used.
  • Write for readers first; a page that reads naturally almost always has a healthy distribution.

Limits

  • Fetching a URL reads the HTML the server sends; text added later by JavaScript is not included.
  • Only public http:// and https:// pages can be fetched, the text of menus and footers on the page is included in the count, while scripts and styles are ignored.
  • The analysis looks at single words, so phrases such as “meta description” are counted as two separate words.
  • Your saved preferences stay in your own browser's local storage.

What to do next

Once your wording is balanced, check the page's tags with the Meta Tags Extractor and write better titles and descriptions with the Meta Tag Generator. For a full page review use the SEO Analyzer.
