Keyword Density Checker
Repeating a keyword too often can look like stuffing to both readers and search engines, while using it too rarely can weaken relevance. This tool counts word frequency in your text so you can see the actual balance.
How to Use This Tool
- Paste your article or page content.
- Adjust the stop-word list if needed — common words like "the" and "and" are excluded by default.
- Click Check Density to see the top 25 terms by frequency and their density percentage.
Why Use ToolVigo's Keyword Density Checker
- Excludes common stop words so real keywords stand out.
- Shows both raw count and density percentage.
- Works on any pasted text, no character limit beyond browser performance.
Limitations
Only counts single words, not multi-word phrases, and does not account for stemming (e.g. "run" and "running" are counted separately).
Privacy & Security
This tool runs entirely in your browser. Nothing you type is uploaded to ToolVigo's servers or stored anywhere.
Frequently Asked Questions
What keyword density is considered ideal?
There is no universally agreed target; modern SEO guidance generally favors writing naturally for readers over hitting a specific percentage.
Can high keyword density hurt my rankings?
Unnaturally repeating a phrase can look like keyword stuffing, which search engines may treat as a negative quality signal rather than a positive relevance signal.
