Keyword Density Checker

Analyze keyword density and frequency in your content. Optimize SEO by finding over-optimized and under-used keywords.

About this calculator

Find over-optimised and under-used keywords. Paste your page copy and a target term and get the count, density and a ranked list of the words and phrases that dominate the text.

Use it to balance a page: the main keyword should appear naturally, supported by related terms.

How to use it

  1. Paste the page content.
  2. Enter your target keyword.
  3. Press Analyze Density.

Formula

Keyword density = occurrences of the keyword ÷ total words × 100. For a phrase, each occurrence of the full phrase counts once. There is no official 'ideal' density: search engines read meaning, not percentages. A natural range is about 0.5% to 2%, and anything higher usually reads as stuffing.
