Keyword Density Checker

Not a fixed one, no — Google stopped rewarding a specific percentage a long time ago, and modern ranking systems look at semantic relevance and how naturally a topic is covered, not word-frequency math. This tool's 'optimal' range is a sanity check against obviously thin or obviously stuffed content, not a target to hit exactly.

The same keyword count reads very differently depending on how much content surrounds it. Repeating a term 5 times in a 100-word page is a much higher density than repeating it 5 times in a 1,000-word page — so the optimal range tightens as content gets longer, which is why this tool adjusts its thresholds by content length rather than using one fixed number for every page.

It's a proxy for keyword stuffing — repeating a term far more than natural writing would, usually in an attempt to signal relevance to search engines. Modern algorithms are good at detecting this and it can work against you rather than for you. If a keyword shows as High, the fix is almost always to rewrite for variety (synonyms, related phrases) rather than removing the topic altogether.
