Keyword Density Checker

Check keyword frequency, density percentage, repeated terms, and overuse warnings.

Keyword density is only one signal, but it is still useful for spotting underused terms, accidental stuffing, and missed topical focus.

Publishing note

Review before you publish or paste

The output is designed to save time, not to skip editorial judgment. Use the result as a polished starting point, then tune it to the exact page, audience, or platform.

Tool input

Generate locally

Nothing here calls a paid API, AI service, or third-party dependency. The output is created inside your local PHP and JavaScript stack.

1

Fill in the fields with the clearest version of your topic, keyword, or draft text.

2

Generate the result and compare the first output against the real page intent.

3

Refine the final version before you publish, share, or paste it into the CMS.

Output panel

Copy, review, refine

Use the result as a first draft, then polish it to match the exact promise and context of the real page, post, image, or campaign.

Submit the form to generate a result. JavaScript enhances the page, but the main processing also works through standard form posts.

Before you copy the final version

  • Read the draft aloud if the keyword feels repetitive.
  • Look at topical coverage, not only one phrase.
  • Use the warning as a prompt for review, not a hard rule.

FAQs

Frequently asked questions

Is there a perfect keyword density?

No fixed percentage works for every page. The goal is natural coverage without obvious repetition or stuffing.

Why are stop words excluded from repeated terms?

Common filler words create noise, so removing them makes the frequency list more useful for real optimisation decisions.
