Frequently Asked Questions
What is the difference between a keyword and a key phrase?
A keyword is a single important word. A key phrase (or long-tail keyword) is a 2–4 word combination that carries specific meaning. Both are important for SEO and content analysis.
How are keywords scored?
Keywords are scored by frequency (how often they appear), position (words appearing earlier or in headings score higher), and contextual weight (words in noun phrases score higher than isolated words).
Is my text sent to a server?
No. All extraction runs in your browser using JavaScript NLP algorithms. Your text never leaves your device.
