Frequently Asked Questions

What is an ideal keyword density percentage for SEO articles?
Most SEO experts recommend maintaining a primary keyword density between 1.0% and 2.0%. Anything exceeding 3.0% risks appearing unnatural and triggering search engine keyword stuffing filters.
What are 2-word and 3-word phrases in keyword density analysis?
These are n-gram phrases (combinations of two or three consecutive words) that represent natural search queries (e.g., "free pdf compressor" or "online image editor") rather than isolated individual words.
Does this tool upload my unpublished article drafts to a cloud server?
No. All text parsing and frequency counting execute locally on your computer inside your web browser sandbox. Your unpublished drafts remain 100% private and confidential.
Can I analyze content in languages other than English?
Yes. The frequency parser supports unicode characters and can analyze texts in Spanish, French, German, Hindi, and other languages.
Is there a word count limit on how much text I can paste?
You can paste long-form content containing tens of thousands of words with zero lag, completely free without account registration.
