What this can and cannot tell you.
There is no ideal keyword-density target. Do not stuff words to meet a percentage. Tokenization treats punctuation as separators and does not segment languages without spaces accurately.
How it works.
Text is case-folded and tokenized into Unicode words/numbers. The phrase share is count ÷ available n-gram positions × 100, so percentages use a different denominator for each n. Output contains the top 200 phrases.
Look for awkward repetition in context. There is no ideal percentage to reach and no ranking score in this result. Read the page refresh guide for the next check.
