Analyze keyword density
What does a keyword density calculator do?
This calculator finds repeated word segments in articles, product pages and social copy, then shows each term’s share of the analyzable text. Use it to spot repetitive wording, add useful synonyms and check topical focus—not to replace content quality with a fixed percentage target.
Calculation and tokenization limits
Density = occurrences of one keyword ÷ total analyzed word segments × 100%. When stop words are excluded, common function words are removed from both the count and denominator. The tool uses the browser’s Unicode word segmentation. English is usually predictable, while Chinese segmentation can be approximate and vary by browser or dictionary, so use the result as an editing signal.
Content-improvement example
In an article with 100 analyzed words, “creator” appearing 8 times has an 8% density. If “free” repeats often while the main topic rarely appears, rewrite repeated sentences and add specific detail instead of forcing more keyword repetitions.
How to use
- Paste an article, product-page draft or social post into the text box.
- Optionally remove common stop words and choose how many top terms to show.
- Review occurrences and density, then copy the results while you edit.
Frequently asked questions
What keyword density should I target?
There is no universal safe percentage. Answer the reader’s question thoroughly first, then check for unnatural repetition; search systems do not guarantee rankings from a fixed density alone.
Why can Chinese results differ from another tool?
Chinese has no fixed space boundary, and segmentation depends on a dictionary and rules. This tool uses browser Unicode segmentation for a fast local check, not a linguistic tokenization service.
Does excluding stop words change the percentage?
Yes. Common function words are removed from the total, so the remaining keyword percentages are recalculated using the smaller analyzed-word count.
