Check that your target keyword appears at 1–2% density — not over-stuffed, not absent
What is keyword density and why does it matter?
Keyword density is the percentage of times a keyword or phrase appears in your content relative to the total word count. For example, if "content marketing" appears 5 times in a 500-word article, its density is 1%.
There's a persistent myth about an "ideal" keyword density — a magic number that guarantees top rankings. In reality, search engines reward natural, readable content. Focus on writing for humans first; hitting an exact percentage rarely helps and often hurts.
Search engines detect keyword stuffing through sophisticated algorithms. Overusing a keyword makes content feel robotic and can trigger penalties. Use this tool to spot over-optimization before it becomes a problem.
