How to read this metric
What it measures
Keyword Density is the percentage of times a keyword or phrase appears on a web page compared to the total number of words on that page. It is a classic metric used to evaluate how “focused” a piece of content is on a specific topic.
Why it matters
While search engines have become much more sophisticated (using NLP and semantic search), keyword density still provides a baseline check for relevance. Most importantly, it helps you avoid “keyword stuffing,” which can trigger spam filters and hurt your rankings.
How to optimize density
- Write for Humans First: Natural writing usually results in a healthy keyword density without extra effort.
- Use LSI Keywords: Instead of repeating the exact same keyword, use related terms and synonyms to build topical authority.
- Strategic Placement: Ensure your keyword appears in the H1, first paragraph, and at least one H2, rather than just increasing frequency in the body text.
- Monitor Competitors: Use tools to see the average density of the top-ranking pages for your target keyword and aim for a similar range.
