About This Tool

Keyword Density Checker

Analyse your content for keyword frequency and density to optimise it for SEO without over-stuffing keywords.

Why Use This Tool?

  • Check if your primary keyword appears at the right density (1–3%) for SEO

  • Analyse competitor content for keyword patterns before writing
  • Used by SEO professionals, content writers, and bloggers

Overview

Keyword density refers to how frequently a specific keyword or phrase appears in a piece of content relative to the total word count. It is expressed as a percentage and has been a fundamental concept in SEO since the early days of search engine optimisation. While modern search algorithms are far more sophisticated than simply counting keyword occurrences, ensuring your content has sufficient keyword presence — without overdoing it — remains important for ranking. Our Keyword Density Checker analyses any text you paste and gives you a complete frequency analysis of every word and phrase, sorted by occurrence count. It shows you the density percentage of each keyword, highlights potential keyword stuffing issues, and helps you identify both primary and secondary keywords present in your content. Use it before publishing any blog post, product description, or landing page to ensure your target keywords appear at the right frequency — typically 1–3% for primary keywords.
