Frequently Asked Questions

What density is safe?

1–2% for primary terms reads natural; above ~4% risks stuffing flags. A 1000-word post holds its keyword 10–20 times.

Single vs phrase density?

Both matter: single-word rates catch repetition, phrase rates catch exact-match stuffing. Check the target phrase specifically.

Does density still rank?

Weakly alone — topical coverage and intent match dominate modern ranking. Use density as a stuffing guardrail, not a target.

Does density analysis upload?

No — analysis runs locally in your browser. Text never leaves your device.
