Keyword Density Checker

See which words dominate your copy — frequency and density for on-page SEO.

How this works

The tool tokenizes your text into words, optionally drops ~100 common stop words (the, and, of…), then counts what remains and expresses each word’s share as a percentage.

The top-20 table reveals at a glance whether your target keyword appears naturally — or whether you’re stuffing it.

Frequently Asked Questions

What density should I aim for?

Roughly 1–2% for your primary keyword. Write for humans first; the number just sanity-checks you.

What are stop words?

Ultra-common words (the, and, is) that carry no topical meaning — ignoring them surfaces the words that actually matter.

Does it check phrases too?

This version analyzes single words, which covers the core on-page check most SEOs run.

How to use the Keyword Density Checker

  1. Paste your article text into the box.
  2. Click Analyze — toggle stop words if you like.
  3. Review the table and rebalance any overused keyword.
