Understanding Keyword Density
How we calculate. Keyword density % = (occurrences ÷ total words) × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Keyword Density case uses keyword occurrences 18 and total words 1200. Enter the same figures below to reproduce the worked path.
What is Keyword Density?
A classic on-page SEO metric. Modern ranking systems care more about relevance and helpfulness than a fixed density target.
- Count whole-word matches for the phrase you defined
- Typical ranges often fall around 0.5–2% for primary terms—context matters
- Avoid stuffing that harms readability
The Formula
Worked Example
Common Use Cases
- Content drafts: check primary-term frequency
- Audits: spot stuffing or under-use
- Localization: compare density across languages carefully
Pro Tips
- Prefer semantic coverage over forcing repeats
- Count the exact phrase you care about
- Exclude nav/boilerplate when possible
Limitations: Keyword Density results are educational SEO planning aids—not guarantees of rankings or traffic. Search algorithms and attribution models vary.
FAQ
