About the Keyword Extractor
This keyword extractor identifies the terms a text is actually about, ranking by frequency and significance while filtering out stop words — so the output is meaningful terms rather than "the" and "and".
A keyword extractor answers what a document is about according to the document rather than its author. That distinction is useful: a page you believe is about "project management software" may, on the evidence of its own text, mostly be about "team collaboration".
Stop word filtering is what makes the output usable. The most frequent words in any English text are function words carrying no topical meaning, so removing them is the difference between a ranked list of real terms and a list headed by "the".
For SEO the practical value is checking alignment. If your target term does not appear among the extracted keywords, the page is probably not about it as far as a search engine is concerned. It is also a fast way to see what a competitor page emphasises. Everything runs in your browser.

Frequently asked questions
What does keyword extraction tell me?

Why filter out stop words?
The most frequent words in any English text are function words with no topical meaning. Removing them makes the list useful.
How does this help with SEO?
If your target phrase does not appear among the extracted keywords, the page probably is not about it as far as a search engine is concerned.
Does it find multi-word phrases?
Yes, alongside single terms, since topics are often expressed as phrases.
Is my text uploaded?
No. Extraction happens entirely in your browser.
