Keyword Density Checker
Check keyword density and distribution in your content
The Keyword Density Checker counts how often a word or phrase appears in your text and reports the density as a percentage. Paste your content to see which terms dominate and where they sit, helping you write naturally while still covering your target keyword. Counting is done locally in your browser.

Tips for getting Keyword Density Checker right
- Run the check on your final draft rather than the first version
- Aim for roughly 1-2% density — much higher reads as stuffing to readers and engines alike
- Check your phrase as a whole word to avoid matches inside longer words
- Scan headings and the first paragraph separately — those placements carry the most weight

- Include keywords in the first 100 words and at least one heading

Common Mistakes to Avoid
- Targeting too high a keyword density (above 3%) which looks spammy
- Only checking single-word keywords and missing long-tail phrases
- Ignoring semantic keywords and related terms
- Not considering keyword placement (title, headings, body)
- Comparing density across different content lengths without context
Troubleshooting
- If density seems too high, replace some instances with synonyms
- For very long articles, focus on section-level density rather than overall
- If results look wrong, check for encoding issues in the input text
- Try pasting plain text without formatting for more accurate analysis
- Consider LSI keywords if primary keyword density is maxed out
