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

  1. 1Paste your blog post, landing page copy, or any content into the text area above.
  2. 2The tool analyses your text in real time. Enable Filter stop words to exclude common words like "the" and "and" from the results.
  3. 3Switch between 1-word, 2-word, and 3-word tabs to see single keywords, bigrams, and trigrams ranked by frequency.
  4. 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

Blog Post Optimisation

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.

Landing Page Copy

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.

Competitor Content Analysis

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.

Content Audit

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).

Frequently Asked Questions

Keyword density is the percentage of times a keyword appears in your content relative to the total word count. A density of 1–3% is generally considered optimal for SEO.
Most SEO experts recommend 1–3% for your primary keyword. Above 3–4% may be considered keyword stuffing. Focus on natural, readable content rather than hitting a specific number.
Stop words are common words like "the", "a", "is", "in" that carry little meaning and are excluded from keyword analysis. Filtering them gives a cleaner view of your meaningful keywords.
These are bigrams and trigrams — sequences of 2 or 3 consecutive words. Analysing them helps you find keyword phrases (e.g. "digital marketing") rather than just individual words.
