Keyword Density Checker

Check the most common meaningful words in your draft and see their density as a percentage of total word count.

What is a good keyword density?

There is no preferred ranking percentage and no fixed density that guarantees visibility. Use the table as an editing diagnostic: it can reveal accidental repetition or show that a draft barely names its subject, but the useful result depends on the topic, format, and natural language of the page.

For interpretation examples, use our single canonical keyword density guide.

Frequency and density measure different things

Frequency is a raw count: if a word appears four times, its frequency is four. Density is a percentage: the checker divides that occurrence count by the total number of detected words and multiplies by 100. A word used 4 times in a 200-word draft therefore has a density of 2.00%.

The denominator includes every detected word. The ranked table omits a small built-in list of common English stop words, such as “the”, “and”, and “of”, and also omits tokens shorter than two characters. Those omitted words still contribute to the total word count, so the displayed percentages remain relative to the complete draft.

How to interpret the table

Start with the highest-frequency meaningful words. Ask whether they describe the page accurately, whether repeated wording sounds mechanical, and whether an important concept is missing. Compare passages in context instead of chasing a number. There is no ideal keyword percentage that applies to every query, language, or content type.

The checker counts normalized words separately. It does not automatically merge plurals, spelling variants, synonyms, or semantically related terms. If “calculator” and “calculation” both matter to your review, inspect both rows and read the sentences in which they occur.

How to use the checker

Paste the complete draft into the text area and review the word total before interpreting a percentage. Scan the top rows, locate conspicuous repetitions in the source, and rewrite only where clarity improves. Download the report when you need a snapshot for an editor, or clear the text to begin a new comparison.

Frequently asked questions

Does a percentage predict ranking? No. The calculation describes the current draft; it does not score relevance, authority, intent satisfaction, or search performance.

Should I count keyword variations? Review them, but remember that this tool lists each normalized word separately rather than grouping synonyms automatically.

Is the draft uploaded? No. Analysis and report generation run in your browser.
