Keyword Density Checker counts how often each word appears in pasted text, reporting frequency and share with openly documented token rules. The point of the page is to make the arithmetic inspectable: it states how text is split into tokens, then shows each term's count and its share of the total, so any figure can be reproduced with a search box and a calculator. That matters because density is easy to quote and hard to defend. It is a description of the text in front of you, not a score, not a target, and not a prediction about ranking. Tokenization is whitespace-based, so languages written without spaces are counted as single runs, and the page says so rather than pretending the number means something it does not. Nothing is uploaded, no page is fetched, and no traffic, volume or approval claim appears anywhere on it. It is most useful as a comparison tool: paste a draft, note the counts, revise, and paste it again to see what changed. Punctuation is stripped before counting and case is ignored, so the same term is not split into several rows by a capital letter or a trailing comma, and the counts across a paragraph remain comparable to the counts across a heading.
How to use Keyword Density Checker
- Paste the article text.
- Read the ranked density table.
- Copy the summary or clear to start over.
What you get
- A frequency table: how often each token appears and its share of the total.
- The tokenization rules that produced those counts, so a figure can be reproduced by hand.
- Density as count divided by total tokens - a description of the text, not a score.
When to use Keyword Density Checker
- Spot accidental keyword stuffing before publishing.
- Compare term emphasis across two drafts.
- Check a translated page, where one term may repeat more often than in the source language.
Frequently asked questions about Keyword Density Checker
Does Keyword Density Checker rank my page?
No. It counts words. There are no scores, traffic estimates, or ranking predictions anywhere in this tool.
How are words split?
Letter and digit runs separated by whitespace or punctuation. Arabic splits the same way as English.
Why is Chinese text one giant token?
Chinese, Japanese, and Thai do not use spaces, and this tool ships no dictionary segmenter. Such text counts as single runs.
Does it upload my article?
No. Counting runs locally in your browser; nothing is sent, stored, or logged.
