Sistrix

Sistrix is an SEO platform for agencies and in-house teams, built in Germany since 2003 around its own Visibility Index for Google and Amazon rankings.

Sistrix is an SEO platform for teams whose traffic depends on ranking in Google. It starts from one number, the SISTRIX Visibility Index, which condenses a domain's ranking positions into a single curve, so a traffic drop can be traced back to the week it began and the keywords behind it. The same measure covers competing domains, so a site can be read against the ones taking its clicks. SISTRIX GmbH has built and run the toolbox from Germany since 2003 and owns it outright. Keyword Research supplies search volume, intent and related terms from the vendor's own keyword database, and ranking keywords are grouped automatically into topics. Domain Analysis and the backlink index cover referring domains, top linked pages and links a site has lost. The Optimizer is the project side: it crawls a site with JavaScript and mobile rendering, reports crawl and on-page errors, and monitors chosen keywords daily by country and language, recording SERP screenshots and AI Overview presence alongside. Content Assistant AI scores a draft against the current top results for its keyword, with Content Planner, Content Discovery and plagiarism checks beside it. Marketplace analysis adds Amazon product, brand, retailer and category research, and Prompt Monitoring tracks how AI assistants answer prompts about a brand, covering sentiment, the competitors recommended instead and the sources those answers draw on. Sistrix suits freelancers and consultants who want their own ranking data without an enterprise contract, in-house teams growing organic traffic, agencies reporting to clients under their own brand, and large enterprises that need roles, rights and an audit log. It fits teams comparing visibility across several countries and languages, and retailers watching Amazon listings beside Google rankings. It is bought as one account on a package that sets seats, projects, crawl volume and how far the data history reaches, billed monthly and cancelable monthly, with extra seats, projects, crawls and credits charged per unit. The two larger packages begin with a demo request rather than self-serve signup. Most of the work here is recurring: watching visibility after a Google update, auditing a backlink profile, checking a site for crawl errors before a release, and finding pages that compete with each other for the same query. Reports, dashboards, lists and alerts carry the answers to colleagues and clients, and white-label reporting takes the vendor's branding off the page for agency work. Google Search Console and Google Analytics connect on the higher packages, so ranking data sits beside a site's own click and session figures. The SISTRIX API moves keyword, link and domain data into a BI stack or a client dashboard for teams that would rather build their own view.
