Keyword Density Checker
Analyse keyword frequency and density in your content for SEO.
What is the Free Keyword Density Checker?
The free Keyword Density Checker scans any article or blog post you paste in and shows you every keyword alongside its occurrence count and percentage density — displayed in a sortable table you can copy as TSV. A top-N selector lets you show the 10, 20, 30, or 50 most-used keywords. SEO writers and content editors use it to balance keyword usage and avoid over-optimisation.
- → Audit an existing blog post for keyword over-use before publishing.
- → Verify that your target keyword appears at the right density (typically 1–3%).
- → Compare keyword distribution across multiple drafts of the same article.
- → Identify unintentional filler words that are eating into your keyword budget.
- → Optimise on-page SEO without expensive software subscriptions.
