Keyword Density Checker: limits and things worth knowing

• Keyword density has not been a meaningful ranking factor for many years. Search engines moved to semantic and entity-based analysis long ago, and there is no target percentage to hit.
• It remains useful in one direction: an unusually high density flags keyword stuffing, which is a spam signal. Anything above about 3% is worth looking at.
• Density is skewed by boilerplate. Navigation, footers and repeated calls to action inflate counts without reflecting the content.
• Covering related concepts matters far more than repeating one phrase.

Is it private and secure?

Your privacy is built in. Keyword Density Checker runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
