What Is the Keyword Density Checker?
Keyword density measures how often a specific keyword appears relative to the total word count. This tool analyzes your content and shows which keywords dominate, helping you avoid both under-optimization and keyword stuffing.
Modern SEO focuses on natural language, but knowing your keyword distribution helps ensure you're covering your target topics adequately.
How It Works
Paste your content and optionally enter a target keyword. The tool calculates total words, unique words, and the frequency/density of each keyword. If you specify a target keyword, it highlights that keyword's density specifically.
Aim for 1-2% density for your primary keyword. Above 3% risks appearing spammy to search engines.

Frequently asked questions
What's the ideal keyword density?
1-2% for your primary keyword is generally safe. Focus more on covering the topic comprehensively with related terms rather than hitting an exact percentage.
Can keyword stuffing hurt my rankings?
Yes. Google's algorithms detect unnatural keyword repetition and may penalize pages that stuff keywords. Write naturally and use this tool to verify you haven't accidentally over-optimized.
