How to use this calculator

Frequently asked questions
What keyword density should I aim for?
There is no universal perfect density. Most SEO practitioners recommend 1–3% as a safe range. More important than density is natural usage, semantic variations, and placing the keyword in the title, headings, and first 100 words.
What is keyword stuffing?
Keyword stuffing is the practice of overloading a page with keywords to manipulate rankings. Google's algorithms detect and penalise this. A density above 5–6% with unnatural repetition is a strong warning sign.
Should I count keyword variations?
Use this tool for the exact keyword. For broader analysis, also check variations (plurals, synonyms) manually. Modern SEO focuses on semantic relevance — covering a topic thoroughly matters more than hitting an exact density number.

Why keyword density still matters (in context)
While Google no longer uses keyword density as a direct ranking signal, the frequency and placement of your target keyword still provides topical signals. The keyword should appear in the title tag, H1, first 150 words, at least one subheading, and the meta description — these placements matter more than overall density.
Beyond density: TF-IDF and semantic SEO
Modern on-page SEO uses TF-IDF (term frequency–inverse document frequency) to compare how often a term appears in your content vs how often it appears across the web. Tools like Surfer SEO and Clearscope use this. The key insight: include related terms and synonyms, not just the exact keyword, to signal topical depth to search engines.
