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
- Paste the page content.
- Enter your target keyword.
- 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.
