Article Keyword Density Calculator

Measure how often a keyword or phrase appears relative to the article's word count.

How to use Article Keyword Density Calculator

1. Enter Article Text, Keyword or Phrase. 2. Matching is case-insensitive, whitespace-token based and non-overlapping. Attached punctuation remains part of the token, so cat and cat, differ. Substrings such as catapult do not match cat. This is a text statistic, not an SEO ranking recommendation. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.

Why use this tool?

Matching is case-insensitive, whitespace-token based and non-overlapping. Attached punctuation remains part of the token, so cat and cat, differ. Substrings such as catapult do not match cat. This is a text statistic, not an SEO ranking recommendation.

How the calculation works

Density = non-overlapping matching phrase tokens ÷ article tokens × 100, multiplied by phrase length. Matching is case-insensitive, whitespace-token based and non-overlapping. Attached punctuation remains part of the token, so cat and cat, differ. Substrings such as catapult do not match cat. This is a text statistic, not an SEO ranking recommendation. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.

Example

Worked example: Article Text = "cat catapult cat dog"; Keyword or Phrase = "cat". Result: 2 occurrence(s), 50%.

Practical tip

Check the input labels and assumptions against the article keyword density task before reusing the number.
