How to use keyword density analysis
Keyword density analysis helps you understand how your content is structured from a search engine's perspective. While modern SEO has moved beyond simple keyword counting, density analysis remains a useful diagnostic tool.
Avoid Keyword Stuffing
If your primary keyword appears at more than 3% density, search engines may flag it as keyword stuffing. This can lead to ranking penalties. Use this tool to ensure your keyword usage feels natural and varies with synonyms and related terms.
Discover Content Themes
The 2-gram and 3-gram analysis reveals the key topics and themes in your content. Compare this against your target keywords to ensure your content actually focuses on the right topics. Often, content drifts from its intended focus.
Competitor Content Analysis
Run this analysis on competitor pages that rank well for your target keywords. Understanding their keyword usage patterns helps you create content that covers the same topics more thoroughly while maintaining natural language.
Content Gaps
If an important keyword doesn't appear in your density results, your content may not adequately cover that topic. Add relevant sections or paragraphs that naturally incorporate missing keywords and related concepts.
Keyword density — common questions
What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears on a page relative to the total word count. For example, if a 1,000-word article mentions 'SEO tools' 15 times, the keyword density is 1.5%. It helps identify over-optimization (keyword stuffing) and under-optimization.
What is the ideal keyword density?
There's no perfect number, but most SEO experts recommend 1-2% for primary keywords. More important than density is natural usage, semantic variations, and topical coverage. Over 3% may signal keyword stuffing to search engines.
What are n-grams?
N-grams are sequences of N words. 1-grams (unigrams) are single words, 2-grams (bigrams) are two-word phrases, and 3-grams (trigrams) are three-word phrases. Analyzing multi-word phrases helps identify your content's key topics and themes.
Can I analyze a competitor's page?
Yes. Enter any public URL to analyze its keyword density. This is useful for understanding what keywords competitors are targeting and how they structure their content.
