About the Keyword Density Checker
The Keyword Density Checker analyses any block of text and reports total and unique word counts, reading time, and the most frequent single words, two-word and three-word phrases with their density percentage. It flags any term that crosses the over-optimisation threshold so your content reads naturally instead of tripping spam signals.
Frequently asked questions
There is no magic number, but staying under about 2–3% for any single term keeps content reading naturally. This tool flags anything above 4%, which is where text starts to look stuffed to both readers and search engines.
Not directly. Modern search engines understand topics, not raw repetition. Density is most useful as a warning system — to catch accidental over-use of a phrase — rather than a target to hit.
