Work starts the moment you drop a file
No daily limit, no sign-up, no watermark
Search engines do not publish a target percentage. Repetition can signal thin or spammy copy when it is unnatural. Use this tool to spot overuse and gaps, not to chase an obsolete SEO myth.
Words use Unicode letter and number rules, so non-Latin scripts are included. Stopwords filter common English function words when enabled. Bigrams are adjacent word pairs after the same tokenisation.
No TF-IDF, no SERP comparison, no n-grams beyond two words, and no language detection beyond the English stopword list.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
Title, description, optional Open Graph/Twitter tags — escaped HTML, no meta keywords.
Append utm_source, utm_medium, and campaign params with lowercase hints — existing query params preserved.
Approximate large-image and compact link cards plus copyable og/twitter meta — not a live platform fetch.
Build a urlset XML from a URL list with escaping, dedupe, and optional download — in your browser.
Compose robots.txt with Allow/Disallow lines, sitemap URL, and warnings for Disallow: /.
