Free Keyword Density Checker

Why Use Our Free Keyword Density Checker?

Keyword density is the percentage of times a specific keyword or phrase appears on a webpage compared to the total number of words. Maintaining the right balance is critical for SEO.

• Avoid Keyword Stuffing: Google heavily penalizes websites that spam keywords unnaturally. A good rule of thumb is to keep your primary keyword density between 1% and 3%. Our tool highlights high-density words in orange and red to warn you.
• Discover LSI Opportunities: By looking at the 2-word and 3-word phrase tables, you can ensure that you are using secondary (LSI) keywords effectively to provide context to search engines.
• Stop Words Filtered: The tool automatically ignores common English stop words (like "the", "and", "is", "a") so you only see the data that actually matters for your SEO.
• 100% Free & Real-Time: No server uploads. The analysis happens entirely offline inside your browser, guaranteeing your article's privacy and providing instant results.
