Check Keyword Density — FreeWhat is keyword density?
Keyword density is the percentage of times a word or phrase appears relative to total word count. If your 1,000-word article mentions "best running shoes" 25 times, that's 2.5% density — borderline. Our checker breaks down single words, two-word phrases, and three-word phrases separately, because stuffing usually hides in the phrases, not the single words.
The safe zones in 2026
Primary keyword: 1–2%. Secondary keywords: 0.5–1%. Anything consistently above 3% deserves a rewrite. But don't chase density as a ranking tactic — modern SEO rewards topical coverage (answering the query fully) far more than keyword repetition. Use this tool defensively: to detect accidents, not to engineer rankings.
How to fix stuffing without losing rankings
Replace repeats with pronouns and synonyms, merge repetitive sentences, and add related subtopics instead of repeating the head term. Then re-check with our readability checker — stuffed content almost always reads worse too.
