Keyword Density Checker

A keyword density checker analyzes a webpage and counts how often each word and phrase appears. It calculates the density percentage — the ratio of each keyword's frequency to the total word count — giving you a clear picture of what topics the page focuses on.

This is especially useful for on-page SEO audits. You can quickly spot over-optimized keywords (keyword stuffing), identify content gaps, or verify that your target keywords appear with the right frequency. The tool also breaks down results by single words, 2-word phrases, and 3-word phrases so you can analyze both individual terms and common expressions.

Keyword density is just one signal in a broader SEO strategy. Search engines like Google look at hundreds of factors when ranking pages, but ensuring your target keywords appear naturally and at a reasonable frequency is still a valuable on-page practice. A density that's too low may indicate the page isn't focused enough on the topic, while a density that's too high can look unnatural and may lead to keyword stuffing penalties.
