Keyword density is a crucial SEO metric indicating how often a keyword appears on a page relative to the total number of words. For example, if the keyword "keyword density" appears 10 times in a 500-word article, the density is 2%. Best practices recommend keeping keyword density between 1% and 2% to avoid keyword stuffing. Focus on readability, natural language, and topical relevance rather than repeating the same term excessively. This tool analyzes single words (unigrams) and multi-word phrases (bigrams, trigrams). It supports stopword filtering, stemming, diacritic normalization, and highlights target keywords in the text.
Recommendations
- • Consider writing at least 200 words for richer content.
- • Lexical density is low; consider using more content-specific terms.

How Keyword Density Works
Keyword density measures how frequently a keyword appears relative to the total word count. This tool computes single-word and multi-word phrase frequencies (n-grams), supports stopword filtering, optional stemming, and diacritic normalization.
Best Practices
- Keep primary keyword density around 1%–2% to avoid keyword stuffing.
- Focus on semantic relevance and readability rather than repetition.
- Use related phrases and variations naturally throughout the content.
Tips
- Enable “Treat input as HTML” when pasting web pages to strip tags.
- Use Custom Stopwords to ignore brand names or common terms specific to your content.
- Click any row to instantly highlight that keyword or phrase in the text.
