Sistrix
Sistrix is a German SEO toolset built around the Sistrix Visibility Index — a ranking-visibility score tracked on a fixed schedule for roughly a million keywords per market, going back to 2008. It also bundles on-page auditing, backlink data, and content optimization tools.
Sistrix has run its own crawler against Google's search results since February 2008, tracking around a million keywords a market on a fixed weekly-to-daily schedule with an unchanged weighting formula — no third-party API sells that same multi-year ranking archive.
What you lose building it yourself
- ✕Competitor visibility trends — Search Console only covers sites you own
- ✕18 years of apples-to-apples ranking history
- ✕Crawl infrastructure built to run at that scale without getting blocked
BUILD YOUR OWN · NOT OFFERED
Matching Sistrix means crawling Google's results for roughly a million keywords per market on a recurring schedule, indefinitely, without getting rate-limited or blocked — plus holding the exact same weighting formula stable for 18 years so old and new data stay comparable. That's a standing crawl-infrastructure and data-integrity commitment, not a weekend project. Entries with a real DIY path get a stack and a prompt here instead; this one doesn't have one.

QUESTIONS
What is the Sistrix Visibility Index?
A single score per domain built from roughly a million tracked keywords, weighted by search volume and expected click-through rate, recalculated on a fixed schedule since 2008 — Sistrix's own metric, not an official Google number.
Does Sistrix's backlink data come from its own crawl?
Partly — Sistrix blends its own crawl with data from partners including Majestic, so the backlink index isn't purely first-party the way the Visibility Index is.
Is Sistrix only useful for German-market SEO?
No — it started in Germany in 2008 but now tracks over 50 countries; German-market coverage and history are simply its deepest, given where it launched.
