For example, if your keyword appears 5 times in 100 words, your keyword density is 5%. It's one of the foundational on-page SEO factors. In real world SEO. keyword density is not about stuffing keywords again and again. Instead, it helps you understand whether your content is naturally focused on a topic or not. Search engines are now smart, so they look at context, meaning, and user intent, not just keyword repetition.
Example: 500 words article with 10 keyword mentions = 2% Density
