Keyword Density Checker
Check keyword density and distribution in your content
Paste text to see word and phrase counts update automatically. Density is the number of occurrences divided by the counted words, multiplied by 100, including for phrases. For example, red fox red fox has four counted words and two occurrences of red fox, giving 50%. This is a diagnostic measure, not an SEO score. Counting runs locally in your browser.

Common Mistakes to Avoid
- Treating density as a ranking score or a universal target
- Expecting synonyms or word forms to count as the same keyword
- Expecting the tool to locate keywords in headings or fetch a URL
- Comparing different text selections without considering their length
Troubleshooting
- Single-character words are excluded from the counted total
- Common English words are hidden from the single-word list but remain in the counted total
- The word rules are designed for English; accented and non-Latin text may be counted incorrectly
- Punctuation is removed, which can join words separated only by punctuation
- Use single spaces between target phrase words; matching ignores case but does not combine synonyms
