What is Keyword Density?
Keyword density is the percentage of times a target keyword appears in your content compared to the total word count. It's calculated as: (keyword occurrences ÷ total words) × 100. It has long been used as a basic on-page SEO signal.
While modern SEO focuses more on topical relevance and natural language than raw keyword counts, monitoring density still helps you avoid keyword stuffing (which can trigger penalties) and ensure your target terms appear often enough for search engines to understand your topic.
How to Use This Tool
- 1Paste your blog post, landing page copy, or any content into the text area above.
- 2The tool analyses your text in real time. Enable Filter stop words to exclude common words like "the" and "and" from the results.
- 3Switch between 1-word, 2-word, and 3-word tabs to see single keywords, bigrams, and trigrams ranked by frequency.
- 4Look at the Density % column. Aim for 1–3% for your primary keyword. Anything shown in red (above 3%) may indicate over-optimisation.
Use Cases
Check that your target keyword appears naturally throughout your article at an appropriate density before publishing. Spot any accidental over-repetition that could look spammy.
Verify your landing page uses your primary and secondary keywords at the right frequency. Use the phrase tabs to discover natural keyword clusters in your copy.
Paste a competitor's page content to see which keywords they emphasise. Use their keyword mix to inform your own content strategy and topical coverage.
During an SEO audit, paste each page's body copy to check if pages are targeting the right keywords — and whether any are accidentally optimising for the same terms (keyword cannibalism).
