How is keyword density calculated?

Keyword density = (times keyword appears ÷ total word count) x 100.

Does high keyword density improve SEO?

Not necessarily, and can hurt — search engines penalize "keyword stuffing." Natural, readable content generally performs better.

What keyword density is reasonable?

There's no strict rule, but many SEO practitioners suggest a natural-sounding range rather than targeting a fixed percentage.

What Is the Keyword Density Calculator?

The Keyword Density Calculator counts how many times a keyword or phrase appears in a block of text and expresses it as a percentage of the total word count — a quick reference check when reviewing content for natural keyword usage.

Formula Used

Density (%) = (Keyword Occurrences ÷ Total Word Count) × 100

This counts whole-word, case-insensitive matches. There's no universally 'correct' keyword density — most modern SEO guidance favors natural, readable writing over hitting a specific percentage target.

How to Use This Calculator

Paste your article, blog post, or page text into the box.
Enter the keyword or short phrase you want to check.
Click Calculate to see the occurrence count and density percentage.

Worked Example

In a 500-word article where the phrase "online calculator" appears 6 times, the density is (6 ÷ 500) × 100 = 1.2%, a fairly natural, moderate usage rate.
