— what it is

Keyword density — how often a term appears relative to the total word count — is one of the signals that tells search engines what a page is about. Too low and your page may not rank for the term; too high and it reads as keyword-stuffed. This tool analyses your text, surfaces the top keywords and n-gram phrases, shows density as a percentage and a visual bar, and gives you a specific recommendation for any target keyword you choose.

— frequently asked questions

What is a good keyword density?

Generally 0.5–2.5% for a primary keyword. Below 0.5% the page may not signal the topic clearly; above 2.5% risks over-optimisation.

Why are common words like "the" excluded?

Stop words are grammatical filler words that appear in every piece of text and carry no topical meaning. The tool filters them by default so results focus on meaningful keywords.

Can I analyse a live URL?

Yes — switch to Fetch URL mode. The tool retrieves the page via a CORS proxy and strips the HTML to analyse the text content.

What format is the CSV export?

keyword, count, density% — one row per keyword, sorted by count.

Is this free?

Yes — free with no sign-in.
