Keyword Density Checker
Analyze keyword frequency and density for SEO optimization
What Is Keyword Density?
Keyword density is the percentage of times a keyword appears on a page compared to the total number of words. It is calculated by dividing the number of keyword occurrences by the total word count and multiplying by 100. For example, if a keyword appears 5 times in a 500-word article, the keyword density is 1%.
Why N-Grams Matter for SEO
N-grams (multi-word phrases) are crucial for SEO because search engines understand context through phrase matching. Analyzing 2-word and 3-word phrases reveals long-tail keyword opportunities and helps ensure your content naturally includes relevant phrases that users search for.
Keyword Density Best Practices
Focus on writing naturally rather than hitting exact density numbers. Use your primary keyword in the title, first paragraph, headings, and conclusion. Include synonyms and related terms (LSI keywords) to help search engines understand your topic without keyword stuffing. Modern SEO values semantic relevance over exact keyword matching.
