Keyword Density Analyzer
Analyze text for keyword frequency, density percentages, and n-gram occurrences to optimize content SEO.
What is the Keyword Density Analyzer?
Keyword density analysis calculates token frequency distributions and n-gram occurrences across written copy to evaluate search engine relevance. The lexical analyzer tokenizes text bodies, filters common stopwords, and calculates proportional density metrics across single words and multi-word keyphrases. This enables content strategists and SEO specialists to optimize editorial copy, avoid keyword stuffing penalties, and satisfy algorithmic search guidelines.
