Frequently asked questions

What keyword density is best for SEO?

There is no ideal percentage. Use density as a signal for natural language, topical coverage and accidental repetition.

Does this calculate TF-IDF?

No. This tool counts phrase frequency and density in one document. TF-IDF needs a comparison corpus.

Is my text uploaded?

No. The analysis runs locally in your browser.
