Signal-first
We prioritize actionable signals: growth, movers, channel mix, and market pressure — not vanity dashboards.
The monthly index of the web's busiest domains.
Domsilo tracks 340 million domains and publishes a fresh traffic index every month — visit estimates, revenue signals, traffic sources, geography and technology stacks, all in one place.
We built Domsilo because reliable traffic data shouldn't require a sales call. The core index is free to explore, the methodology is documented, and every page tells you exactly which data month you're looking at.
Workflow-driven
From discovery to deep dive to monitoring, each page is shaped around fast research loops.
Verifiable data
Every number is attributable to its data month, and reports link straight to Whois and the Internet Archive.
