Keyword Density Checker
See the most frequent words and their density percentage in your content — optimize without stuffing.
Analyze your content's keyword density
The Keyword Density Checker scans your text and shows which words appear most often, with their exact count and density percentage. Paste an article, product description, or blog post and instantly see how your content is weighted — so you can optimize for your target terms without overdoing it. It runs entirely in your browser.
What is keyword density?
Keyword density is the percentage of times a word appears relative to the total word count. If a 1,000-word article uses "running shoes" 15 times, that phrase has a density of 1.5%. It is a quick way to gauge whether your content actually emphasizes the topics you want to rank for — or whether you have drifted off-topic or, worse, stuffed a keyword unnaturally.
How to use it
- Paste your content into the box.
- Optionally ignore common stop words to focus on meaningful terms.
- Review the top keywords, their counts, and density bars.
What density should you aim for?
| Density | Interpretation |
|---|---|
| Under 0.5% | The term may be underused for the topic |
| 0.5%–2.5% | A natural, healthy range for a main keyword |
| Over 3–4% | Risk of keyword stuffing — sounds unnatural |
Avoid keyword stuffing
There is no magic density number, and modern search engines are sophisticated about understanding meaning rather than counting words. Cramming a keyword in repeatedly ("keyword stuffing") reads badly and can hurt rankings. Use this tool to confirm your topic is well represented and to catch accidental over-repetition — then write naturally for your readers first.
Beyond single keywords
- Check related terms. Strong content uses synonyms and related concepts, not just one phrase.
- Spot filler. If meaningless words dominate, tighten your writing.
- Compare to competitors. Paste a top-ranking page to see how it is weighted.

Frequently asked questions
What is a good keyword density?
There is no exact target, but roughly 0.5%–2.5% for a main keyword reads naturally. Above 3–4% risks keyword stuffing.
What are stop words?
Common words like 'the', 'a', and 'and' that carry little meaning. You can ignore them to focus on significant terms.
Does keyword density still matter for SEO?
It is a useful sanity check, but write for readers first. Search engines understand meaning, not just word counts.
