Keyword Density Checker

Keyword density refers to how often your target keyword appears in a piece of content relative to the total word count, expressed as a percentage. Strike the right balance and search engines understand your page clearly. Go too high and you risk keyword stuffing penalties. Too low and the page may not rank for your intended term at all. The Keyword Density Checker gives you an instant, accurate breakdown of every keyword's frequency in any content you paste — so you can optimise confidently before hitting publish.

How It Works

Paste your article, blog post, or page content into the input field and click Analyse. The tool counts every word, calculates the frequency and density percentage of each term, and returns a sortable table ranked from highest to lowest occurrence. Use the results to confirm your primary keyword receives appropriate emphasis and identify any secondary terms that are over-represented.
