  1. Paste the draft or page copy.
  2. Enter the keyword or phrase you want to check.
  3. Review occurrences, total words, and keyword density.
  4. Use the result as a sanity check, then edit for usefulness and readability.

Calculator use

Best for

  • Writing, editing, naming, or formatting content for a specific platform or constraint.
  • Text length, structure, or output checks before publishing or handing work off.

Before relying on it

Check first

  • Density is a rough editing check, not a ranking target. Helpful content matters more than forcing a percentage.
  • Counting drafts with hidden boilerplate, copied notes, or placeholder text still included.
  • Ignoring platform-specific limits, formatting, or truncation rules.

Under 0.5%: Light mention.

The topic may be present, but the phrase is not repeated often.

0.5% - 2%: Common editing range.

Often reads naturally when the phrase fits the page topic.

FAQ

Common questions

Is keyword density still important for SEO?

It is best treated as an editing check. Search engines care about useful, relevant content, not hitting a magic density number.

Does this count phrases?

Yes. Enter a single word or a multi-word phrase and the tool counts matching occurrences.

Should I increase density if it looks low?

Only if the page is missing useful coverage. Do not add repeated keywords just to raise the percentage.

Do text tools publish final copy?

No. Treat generated or checked text as a draft. Review tone, factual accuracy, claims, brand voice, platform fit, and any legal or policy requirements.

Why should platform limits be rechecked?

Platforms can change limits, truncation behavior, display formats, and policy rules, so verify important posts in the publishing interface.
