What is it?
What is a keyword density checker?
A keyword density checker measures how often a word or phrase appears in a piece of content, expressed as a percentage of total words. Modern SEO doesn't reward keyword stuffing, but density still matters as a signal: too low and the page reads off-topic, too high and Google's helpful-content systems flag it as thin or spammy. Our free keyword density checker reports single-word, 2-word, and 3-word phrase frequencies from any URL or pasted text, flags terms that look over-optimized, and benchmarks your density against what AI-search engines (ChatGPT, Perplexity, Gemini) cite for the same topic.
How to use the keyword density checker
Paste a live URL or a block of draft text into the input. The tool strips boilerplate, counts every word and phrase, and returns a ranked density table: primary term, related terms, and long-tail variants with their exact counts and percentages. Use it to audit competitors (what are they over-weighting?), validate new drafts before publishing, or compare your density against the keyword set from our AI Keyword Tool. Pair with the Semantic Validator to confirm topical coverage beyond just exact-match frequency.

Audit competitor pages
Paste any competitor URL to reveal which keywords they're actually weighting. Use their density pattern as a comprehensiveness floor, not as a keyword-stuffing target.

FAQ
What's a good keyword density for SEO in 2026?
There is no official target. Most top-ranking pages land in the 0.5%–2% range for their primary keyword. Anything above 3% risks triggering Google's helpful-content or keyword-stuffing filters. Focus on natural phrasing and topical coverage (2/3-word phrases), not on hitting a specific percentage.
Is keyword density still a Google ranking factor?
Not directly — Google has explicitly said there's no optimal density number. But extreme densities still act as a negative signal. Too high = stuffing penalty; too low = topical mismatch. The checker is a diagnostic tool to keep your content in the safe, natural-reading zone.
Can I check density by URL as well as pasted text?
Yes. Paste a live URL and the tool fetches, strips navigation/boilerplate, and analyzes only the main content. Or drop in raw draft text to audit a blog post before you publish it.
Does it analyze 2-word and 3-word phrases, not just single keywords?
Yes — and this is where most free tools stop at single words. Our checker returns single-word, 2-word, and 3-word phrase frequencies, which is how humans actually search and how AI models extract topics.
How does keyword density affect AI search visibility?
LLMs like ChatGPT, Perplexity, and Gemini prefer clean, well-distributed, context-rich passages. Unnaturally repeated keywords trigger low-quality signals. Pages that cover a topic evenly — using varied 2/3-word phrases instead of a single stuffed term — are more likely to be cited. For ongoing citation tracking, pair with our AI Citation Tracker.
