What is Keyword Density Checker?
Keyword density measures how often a word or phrase appears compared with the rest of the text. It is a diagnostic signal for repetition and topical coverage, not a ranking score by itself.
Useful analysis also looks at where terms appear. Titles, headings, descriptions, and links often carry more context than raw body counts. There is no universal ideal percentage.
