In-depth guide

Keyword density: a diagnostic, not a target

Keyword density is the percentage of a page's words made up by a given term or phrase. It is a useful editorial gauge for whether your copy actually covers its topic — but it is not a ranking lever to optimise. This tool counts term frequencies in your text locally and shows the distribution.

How density is calculated

The tool tokenises your text into words, filters out very short tokens and punctuation, and counts how often each term appears. Density for a term is its count divided by the total word count, expressed as a percentage. Ranking the results surfaces which terms dominate your copy and which intended topics are barely mentioned.

How to use this tool

  1. Paste the page copy or draft you want to analyse.
  2. Scan the top terms — do they match the topic you intended to cover?
  3. Look for gaps: important concepts that appear far less than you expected.

Read it as a signal, not a quota

Google does not reward a specific density figure, and chasing one leads to keyword stuffing — a tactic its spam policies explicitly penalise. Use the numbers the other way round: if your target topic barely registers, the page may be under-targeting it; if one phrase is repeated unnaturally often, that is a prompt to rewrite for readers, not search engines.

Privacy

Density metrics support human editing — they never replace it. Always read the copy back to a person before publishing.

Your text is analysed entirely in the browser and is never uploaded. Short tokens (typically under three characters) and punctuation are excluded so the counts reflect meaningful words.

When to use it vs alternatives

Use this tool for quick text transformation, inspection, decoding, testing, or generation without opening a heavier application. Use a project script or test suite when the same transformation must be repeated automatically.

Common pitfalls

  • Check whitespace, casing, escaping, and line endings before using the result in production.
  • Generated or transformed strings can be syntactically valid while still being semantically wrong for your system.
  • Avoid pasting secrets unless you are comfortable handling them in the current browser session.

Frequently asked questions

What words are ignored?

Very short tokens (typically under three characters) and punctuation are filtered out so the counts reflect meaningful words.

Should I optimise for a high density?

No. There is no magic density figure that improves rankings. Prioritise natural language and intent over repetition.

Can this detect keyword stuffing?

It flags terms that appear unusually often, which is a prompt to review — but the judgement of whether copy reads naturally is still yours.

How is density calculated?

It is a term's occurrence count divided by the total word count, shown as a percentage.

Does Google reward a specific density?

No. Google's spam policies explicitly target keyword stuffing, so chasing a density number is counterproductive.

What is the best way to use the results?

Read them as a coverage check: if your intended topic barely registers, the page may be under-targeting it; if one phrase dominates, rewrite for readers.
