Check keyword frequency and density
Analyze how often a word or phrase appears in text and calculate simple keyword density.
Density = keyword occurrences / total words x 100. Do not optimize to a fixed density target; write naturally for the topic and user intent.
How to use the keyword density checker
Paste text and enter a word or phrase. The tool counts exact phrase occurrences and calculates a simple density against total word count.
Keyword density formula
Keyword density = Keyword occurrences / Total word count x 100.
Example: 10 mentions in a 1,000-word article
Ten exact mentions in 1,000 words produce a simple density of 1%. This does not mean 1% is an SEO target.

| Words | 5 mentions | 10 mentions | 20 mentions | 30 mentions |
|---|---|---|---|---|
| 500 | 1% | 2% | 4% | 6% |
| 1,000 | 0.5% | 1% | 2% | 3% |
| 2,000 | 0.25% | 0.5% | 1% | 1.5% |
How to use keyword density responsibly
There is no universal keyword density target. Use the tool to spot accidental repetition, then focus on topical completeness, natural language, entities and user intent instead of forcing a percentage.
