What is Word Density?
The word density analyzer (keyword density checker) counts the frequency of every word and multi-word phrase in your text. It displays the top single words, 2-word bigrams, and 3-word trigrams ranked by occurrence count with density percentages. This is one of the most important SEO content analysis tools — keyword density directly affects how search engines understand your page's topic relevance.
Use it to verify your target keywords appear at the optimal frequency (1-3%), detect accidental keyword stuffing that could trigger search engine penalties, identify unintentional word repetition that makes text feel monotonous, analyze competitor content to understand their keyword strategy, and ensure even keyword distribution throughout your text rather than front-loading.
