Keyword Density Checker

For a natural article, the primary keyword phrase typically lands somewhere between 0.5 percent and 2 percent of total word count without anyone trying to engineer it that way. Numbers well above 3 to 4 percent usually read awkwardly out loud and are a sign of repetitive phrasing rather than thoroughness.

Run the checker against synonyms, plural forms, and closely related terms in addition to the exact keyword. A page that only ever says the exact phrase and never a natural variant often reads as stiff to both readers and to language models that now inform ranking systems.

Keyword stuffing in alt text, hidden divs, or footer text to inflate density is still detectable and still risks a manual action, even though it no longer helps rankings the way it once did. If a phrase feels forced when read aloud, cut it rather than keeping it for density's sake.

The more useful reading of this number is inverted: if your intended keyword barely appears at all, say under 0.2 percent on a 1,500-word page, that's often a sign the content drifted away from the topic it was supposed to cover, not that you need to force the phrase back in artificially. Compare density across a handful of top-ranking competitor pages for the same query to see the rough range they landed in organically, then write toward that range rather than a fixed rule.

Keyword density only counts literal string matches and says nothing about whether you've covered the subtopics, related entities, or common follow-up questions a comprehensive page on the subject would include. Use it alongside, not instead of, an outline check against what top-ranking pages actually discuss, since a page can hit a perfect density number and still be thin on substance.
