No. It is only a content audit signal. Useful content and search intent matter more than a fixed percentage — modern search engines evaluate topical relevance and user satisfaction far more than exact keyword ratios.
No. Paste the text you want to inspect. The tool does not crawl pages or fetch external sites, so it works entirely offline once loaded.
There's no fixed universal threshold, but repetition that reads unnaturally to a human — the same phrase every other sentence — is a reliable red flag regardless of the exact percentage shown.
Multi-word phrase repetition often reveals unnatural or keyword-stuffed writing patterns that single-word counts miss, since a phrase like "best budget laptop" repeating verbatim is a stronger stuffing signal than the word "laptop" alone appearing often.
No — some repetition is natural and even necessary for topical clarity. Use the results to spot excessive or awkward repetition, not to mechanically minimize every repeated word.
Yes. Stopwords (the, and, of, a) naturally dominate raw word counts in any language. Filtering them out surfaces the substantive, topic-relevant terms that actually matter for a content review.
The word- and phrase-counting logic works on any space-separated text, but the built-in stopword list is tuned for English, so non-English text may show common function words as high-frequency terms.
