What is Keyword Density Checker?
Keyword Density Checker is a free online SEO tool that analyzes keyword frequency, keyword density percentage, and phrase repetition in your content. Paste your text or upload a TXT, DOCX, or PDF file, then instantly see word and phrase statistics, 1 to 4-word phrase analysis, first/last occurrence positions, and a color-coded density overview (Excellent, Good, Under-Optimized, Over-Optimized).
Search for custom keywords to check their exact count, density, and position, or highlight every occurrence directly in your content. The tool also flags keyword stuffing, missing keywords, and distribution imbalance, and generates automatic SEO suggestions to help you optimize your writing. Export your findings as a CSV, TXT, or PDF report, or print it directly. All analysis happens locally in your browser — your content is never uploaded anywhere.
