SISTRIX is a German SEO software suite famous for its Visibility Index — the benchmark metric for measuring how prominently a domain performs in organic search results.
Founded in Bonn in 2004, SISTRIX built its reputation on the Visibility Index, a single score that makes winners and losers in Google instantly visible and comparable over more than a decade of history. The SISTRIX Toolbox organizes its data into modules: SEO for visibility, keyword and competitor research; Links for backlink analysis; Optimizer for on-page audits; a Content Assistant for data-driven text optimization; and additional modules covering social media and Amazon visibility. Daily ranking data spans dozens of countries, with particularly deep coverage of European markets, where SISTRIX is the reference tool in most professional SEO teams.
The underlying Visibility Index data stretches back to 2008, giving SISTRIX one of the longest continuous records of Google ranking history available anywhere — invaluable for diagnosing traffic drops after core updates. Alongside the paid Toolbox, the company maintains popular free resources, including its Google Updates overview and the Ask SISTRIX knowledge base, which is why its data is so frequently cited in SEO case studies and industry reporting.
Plans are Start at €119/month, Plus at €239/month, Professional at €419/month and Premium at €799/month (plus tax), all cancellable monthly. A 14-day free trial account lets you test the Toolbox before subscribing.
