🔍 Advanced Keyword Density Checker
When “Exclude Stop Words” is checked, both the total word count and the occurrences are calculated only from the filtered text (stop words removed).
This ensures the Keyword Table and N‑gram Table show identical percentages for the same word/phrase.

Boost Your SEO Accuracy
If you write content for your website or blog, you already know that keywords are the bridge between what people search for and the answers you provide. But how do you know if you’re using the right keywords too often—or not enough?
That’s exactly where a Keyword Density Tool comes in.
What is a Keyword Density Tool?
A Keyword Density Tool analyzes your text and tells you how many times a specific word or phrase appears compared to the total number of words. The result is shown as a percentage called
Keyword Density.
Formula
Density (%) = (Number of Times Keyword Appears ÷ Total Words) × 100
For SEO, most experts recommend a keyword density between 1% and 3% for primary keywords.
- Too low → You might miss ranking opportunities.
- Too high → Search engines may see it as keyword stuffing and penalize your page.
This tool provides accurate, real-time density calculations without AI-generated fake numbers. No API keys, no internet dependency—everything runs directly inside your browser.
