See a site's main platform, ad pixels and Chrome-based traffic history while you browse. See a website's reach, traffic history and technology stack without leaving the page. NicheObserver adds a Domain reach score to your Chrome toolbar. Open the extension for its monthly history, main market and locally detected technologies. • Domain reach: a score from 0 to 100, aggregating observed origins, countries and devices. • Monthly history: explore up to 24 months and switch between Domain reach and Best origin reach. • Main market: see the country and confidence level when the data supports it. • Website technology: identify supported platforms and advertising pixels locally in your browser. • Full report: open the domain's NicheObserver report in one click. Reach uses Google's public Chrome UX Report data. It is a relative indicator, not a visit count. Coverage varies by website and month; an unobserved site does not mean a site without visitors. Automatic profiles start only after you enable them. Each lookup sends the website hostname to NicheObserver over HTTPS. Page paths, page content and locally detected technologies stay in Chrome. You can turn automatic profiles off at any time. No API key is required. You can optionally connect a free NicheObserver account from the extension. Website lookups remain separate from your account. Pin NicheObserver to keep its Reach badge visible as you browse.
