What Is the Keyword Density Checker?
Keyword density is the percentage of times a keyword appears in your text relative to the total word count. Overusing a keyword can trigger search engine spam filters, while underusing it may mean the page does not rank for that term at all. A density of 1-3% is generally considered optimal. This tool analyzes your text, strips common stop words, and ranks the remaining words by frequency so you can spot over-optimized terms instantly.
