About Keyword Extractor
Before you can optimize a page, you need to know what it's actually about in search terms — and reading a long article to pull out its key phrases by hand is slow and subjective. Keyword Extractor analyzes your text and surfaces the primary and secondary keywords it's built around, giving you a clear map of the topics the content emphasizes.
Paste any text and the tool parses it, weighs term significance, and ranks the main and supporting keywords in your browser. It is free, needs no login, and runs instantly. Use it to confirm a draft targets the right terms, to mine existing content for keyword ideas, or to understand the focus of a competitor's page.

FAQ

Enough to be representative — a full article or page gives more reliable results than a single sentence.
