Keyword usage analysis
Keyword Density Checker
Calculate target-keyword frequency, approximate density, prominence, and phrase distribution from pasted copy or the readable text of a public webpage.
Tool guide
What is the Keyword Density Checker?
The Keyword Density Checker counts how often selected words or phrases appear in pasted text or the readable copy of a public webpage. It reports frequency, approximate density, and distribution so editors can spot accidental repetition, missing terminology, or sections that overuse the same phrase.
Keyword density is not a ranking formula. Search engines evaluate meaning, quality, context, entities, links, and user intent rather than requiring one ideal percentage. Use this tool as an editorial diagnostic, not as a target to force every phrase into the copy.

Step-by-step
How to use the Keyword Density Checker
- 1Add the content source
Paste the page copy for the most controlled analysis, or enter a public URL.
- 2Enter target terms
Separate multiple words or phrases with commas or new lines.
- 3Run the count
The tool normalizes spacing and compares each target with the readable text.
- 4Edit naturally
Use the report to improve coverage and remove awkward repetition rather than chasing a percentage.
Interpretation
How to understand the results
- A zero count can reveal that the page never uses an important term, but synonyms may still cover the topic well.
- A high percentage can signal repetitive writing, especially for long exact-match phrases.
- Short pages naturally produce volatile percentages, so interpret density together with total word count.
Practical advice
SEO best practices
- Write a complete answer to the searcher’s need before optimizing phrase frequency.
- Use related terminology, examples, and entities instead of repeating one exact phrase.
- Check headings, introduction, body copy, image captions, and links for natural topic coverage.
- Do not count navigation and footer text as if it were the main article when reviewing editorial quality.
- Read the final copy aloud; unnatural repetition is often easier to hear than to measure.
Before you act
Limitations of this automated check
The URL mode extracts visible text from returned HTML and may include navigation, footer, cookie notices, or repeated templates. It does not evaluate semantic relevance, stemming, synonyms, or the quality of the answer. JavaScript-rendered text may be absent from the fetched source.
Common questions
Keyword Density Checker FAQs
What is the ideal keyword density?
There is no universal ideal percentage. The phrase should appear often enough to make the topic clear without making the writing repetitive.
Does the tool count close variations?
It primarily counts the exact terms or phrases you provide after normalizing case and spacing. Related words should be reviewed separately.
Can high density cause a penalty?
Unnatural keyword stuffing can reduce quality and may be interpreted as spam, but a percentage alone does not determine a penalty.
Why does URL mode show more words than my article?
Shared navigation, footer, banners, and other template text may be included in the page’s readable HTML.
