Free Keyword Density Checker
Paste your content to see word and phrase frequency, density %, and over-optimization warnings. Free, no signup, runs in your browser.
| Keyword | Count | Density |
|---|
Rows over ~3–4% are flagged in red as possible over-optimization.
How to use the keyword density checker
- Paste your text — an article, a landing page, or a draft.
- Switch between 1, 2 and 3-word phrases to see your real topics and target phrases.
- Watch the flagged rows. If your main keyword is in the red zone, rewrite for the reader and ease off the repetition. Export the table as CSV if you want to track it.
What keyword density tells you
Keyword density shows which words and phrases dominate your content. It is most useful for two things: confirming that your intended topic and related terms actually appear, and catching accidental keyword stuffing — repeating a phrase so often it reads unnaturally and risks looking manipulative. Search engines reward content written for people, so treat density as a sanity check, not a target to hit.
Frequently asked questions
What is keyword density?
Keyword density is how often a word or phrase appears in your text as a percentage of the total word count. It is a quick way to see what a page is really "about" and to spot over-use of a term.
What is a good keyword density?
There is no exact target — write naturally for the reader. As a rough guide, a single keyword above about 3–4% can look like keyword stuffing. This tool flags terms in that range so you can ease off.
Does keyword density affect rankings?
Modern search engines understand topics, not raw counts, so there is no magic density number. Use this tool to avoid stuffing and to confirm your main topic and related terms are actually present — not to hit a percentage.
What are 2-word and 3-word phrases?
Also called bigrams and trigrams — multi-word phrases like "running shoes" or "best running shoes". They often reveal your real target keywords better than single words.
Is my text sent anywhere?
No. The analysis runs entirely in your browser — your text never leaves your device. The tool is free and needs no signup.
