About this tool
This page opens the keyword density checker as a keyword stuffing test — paste your copy, enter the target keyword and watch its count and density update live.
Keyword stuffing means repeating a phrase so often that the text stops sounding natural; search engines have treated it as spam for years. The checker shows your keyword's exact density and whether it appears within the first 100 words, and the phrase tables expose any other expression you have been overusing.
The widely quoted 0.5-2% range is a heuristic editors use, not an official ranking rule — if your density is far above it and the sentences feel repetitive, rewrite for readers. Everything is computed locally in your browser, so client pages stay private.
Example. The text cat cat dog shows cat twice at 66.67 percent of three words and dog once at 33.33 percent.
Limit. Phrase tables stop at three words and show at most 15 rows, and a one-word stop word such as the is dropped before the percentage is calculated.
