What Is Keyword Density?
Keyword density is the percentage of analyzed words represented by a particular keyword or phrase. It can be used as a basic content analysis metric when reviewing website copy.
Basic formula
Keyword density = keyword occurrences ÷ total words × 100
Why Check Keyword Density?
Review Content Balance
Identify whether a target term appears very frequently throughout a piece of content.
Edit Website Content
Use density as one of several signals when reviewing landing pages, articles and other website content.
Check Repetition
Find repeated use of a keyword or phrase that may make content sound unnatural.
Support SEO Editing
Combine keyword frequency analysis with search intent, content quality, relevance, readability and user experience.
Important SEO Note
There is no universal keyword-density percentage that guarantees search-engine rankings. Modern SEO focuses on useful, relevant, natural and high-quality content. Avoid artificially repeating keywords simply to reach a numerical target.

How It Works
The tool tokenizes the content into words, identifies the keyword or phrase as a sequence of words and counts exact matching sequences without treating capitalization as significant. It then calculates the percentage based on the total word count.
Automated keyword analysis is a simple measurement tool and does not evaluate search intent, content quality or search-engine algorithms.
