What is the 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.

How to Use the Keyword Density Checker

  1. 1 Paste your article or blog post into the text area labelled "Paste your article or blog post here to analyse keyword density…".
  2. 2 The keyword table populates immediately, sorted by frequency (highest first).
  3. 3 Use the Show top N dropdown — choose 10, 20, 30, or 50 — to control how many keywords appear.
  4. 4 Each row shows the keyword, its count, and its density as a percentage of total words.
  5. 5 Click Copy as TSV to paste the results into a spreadsheet for deeper analysis.
