FAQ

Frequently Asked Questions

Everything you need to know about this tool.

What is a good keyword density for SEO?

Generally, 1–2% for primary keywords and 0.5–1% for secondary keywords is considered optimal. Densities above 3% may be flagged as keyword stuffing by search engines.

What are stop words?

Stop words are common words like "the", "is", "at", "which", and "on" that appear frequently but carry little semantic meaning. Filtering them helps focus on meaningful keywords.

What is an n-gram?

An n-gram is a contiguous sequence of n words. A 1-gram is a single word, a 2-gram is two consecutive words, and a 3-gram is three consecutive words. They help identify key phrases in content.

Can I analyze text in other languages?

Yes, the analyzer works with any text. However, the stop word list is English-specific. For other languages, disable stop word filtering for accurate results.
