Keyword Density guide
Word frequency counts how often each word appears in a draft. Keyword density expresses that count as a share of the words analysed, so you can see at a glance which terms are carrying the piece and which are repeating without adding meaning. Very common words such as “the”, “and”, and “of” are left out of the table so the topic words are easier to read.
How the numbers are worked out
- Density is the number of occurrences divided by the number of words analysed, shown as a percentage.
- Capitalisation is ignored, so “Draft”, “draft”, and “DRAFT” all count towards the same word.
- Single-character tokens and common stop words are skipped. They are still included in the “Words” total shown above the table, which is why that total can sit slightly higher than the figure behind the percentages.
Worked examples
Analyze content content content and the report shows content three times at 100 percent, because it is the only word that survived analysis. Analyze Draft draft DRAFT writing and it reports draft three times at 75 percent and writing once at 25 percent, confirming that capitalisation does not split the count. A draft made only of the word “the” returns no significant keywords, because stop words are excluded by design.
How to use the report
- Check that your main terms appear often enough for a reader to notice them, without forcing them into every paragraph.
- Look for one word dominating the table. That usually signals repetition rather than emphasis.
- Compare two drafts to see whether editing actually reduced repetition.
- Use the numbers as a prompt to revise, not as a target to hit.
What density cannot tell you
Density measures repetition, not quality, intent, or accuracy. No search engine rewards a particular percentage, and a low-density draft is not automatically a better draft. A term can repeat often and still be irrelevant to the reader, and a passage can use varied vocabulary while saying very little. Keyword density also says nothing about whether your claims are sourced or accurate. Read the draft yourself before changing anything because of a percentage.
For total length instead, use the word counter or the reading time and text analyzer. You can also see every tool we have.

Common questions
What counts as a keyword here?
Words longer than one letter that are not on a built-in list of common words, which drops things like "the", "and", "of" and "with". Single letters are excluded too, since they would otherwise fill the top of the list and tell you nothing about what a piece is about.
What is keyword density?
How often a word appears as a share of the total. "Revision" appearing 10 times in 500 words is 2%. It measures repetition, which is not the same as strength — a word can be repeated without being important.
What density should I aim for?
For ordinary prose, above roughly 3% starts to read as repetitive to a human being. Search engines have published no target and have treated keyword stuffing as counterproductive for well over a decade. Write for the reader, then use this to catch one word that has got away from you.
Does it check spelling or grammar?
No. It counts words and frequencies and nothing else. It cannot tell you a word is misspelled, and it does not look at sentence structure or punctuation.
Is the text uploaded?
No. Analysis runs entirely in this tab and your text is not transmitted anywhere.
