Pro Tips
- •Common stop words (like "the", "and", "is") are excluded from the single-word analysis, since they'd otherwise dominate every result without being meaningful
- •There's no single "correct" keyword density - modern SEO focuses more on natural, comprehensive coverage of a topic than hitting a specific percentage
- •A single keyword appearing at an unusually high density compared to everything else can be a sign of keyword stuffing, which search engines may penalize
- •Checking 2 and 3-word phrases can reveal repeated phrasing patterns that a single-word count alone would miss

Frequently Asked Questions
What's a good keyword density percentage?
There's no universally agreed-upon ideal percentage. Modern SEO best practice favors writing naturally and comprehensively about a topic over targeting a specific density number, which was a more common tactic in outdated SEO advice.
Why are words like "the" and "and" excluded?
These common stop words appear frequently in virtually all English text and don't carry meaningful topical information, so excluding them makes the remaining results much more useful for understanding what a piece of content is actually about.
Is my text sent to a server?
No. The entire analysis happens locally in your browser using JavaScript. Your text is never transmitted anywhere, including to this website's own servers.
Why check 2 and 3-word phrases in addition to single words?
Repeated phrases (like "best running shoes") can reveal keyword patterns that analyzing single words alone would miss, since the individual words might not repeat enough on their own to stand out.
Can high keyword density hurt my SEO?
Yes, potentially. Unnaturally repeating a keyword far more than natural writing would (sometimes called keyword stuffing) can be flagged by search engines as a manipulative practice and may hurt rather than help your rankings.
