Frequently asked questions
What is a good keyword density for SEO?+
Aim for 1-2% on your primary keyword. Higher than 3% can read as keyword stuffing and hurt rankings.
Why filter stop words?+
Stop words like "the", "and", "of" dominate frequency tables but say nothing about topic relevance. Filtering them surfaces the keywords that matter.
What are bigrams and trigrams?+
Two-word and three-word phrases. They show how your real key phrases (not isolated words) appear across the content.
Is the tool free?+
Yes — free, no sign-up, runs entirely in your browser.
