Keyword Density Checker

Keyword density is the percentage of times a term appears relative to the total word count. This checker breaks your content into the most common single words and multi-word phrases (n-grams) so you can confirm your target terms are present without over-optimizing.

• Aim for natural usage — there's no magic percentage, but a single keyword above ~3–4% often reads as stuffed.
• Check phrases, not just words — "Chicago SEO" matters more than "Chicago" and "SEO" separately.
• Watch reading time — thin pages rarely outrank comprehensive ones in competitive Chicago niches.
