📈 Keyword Density: Complete Guide for SEO

Keyword density is the percentage of times a keyword appears on a page. Formula: (keyword count ÷ total words) × 100. Ideal density is 1-3% for primary keywords. Higher than 5% risks keyword stuffing penalties.

How Our Tool Works

We remove 150+ common stop words (the, and, of, to, etc.), convert to lowercase, count frequency, and display top keywords with density and visual progress bars.

Why does URL fetch fail?
