Calculate how often a keyword appears in your text as a percentage of total words.
How it works
Keyword density is the percentage of times a specific word or phrase appears in a piece of text relative to the total word count. For example, if a 500-word article mentions 'coffee' 10 times, the keyword density is 2%.
Paste your text and enter the keyword or phrase you want to measure. The tool counts exact occurrences (case-insensitive) and divides by the total word count, then displays the percentage.
SEO practitioners historically aimed for a density of 1-3% for target keywords. Today over-optimization (keyword stuffing) can trigger search engine penalties, so use this tool to confirm you are in a natural range rather than to hit an exact target. It is also useful for content auditing and ensuring a keyword is present at all.
Worked example
Check keyword density in a blog article draft
- Paste the full article text into the Text field.
- Enter 'organic coffee' as the keyword.
- Read the density percentage returned by the tool.
- If density is above 4%, revise to use synonyms or rephrase some instances.
A percentage showing, e.g., 1.8% -- within the natural range, no changes needed.
Common mistakes to avoid
- Targeting an exact density number and rewriting naturally good text to hit it -- readability matters more.
- Forgetting to check multi-word phrases separately from individual words -- 'coffee beans' density differs from 'coffee' density.
- Counting stop words in your own manual calculation -- the tool handles this correctly.
