AI Agentic Readiness
9 / 28
agentic checks passed 45% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
tetra.de is live and passes 9 of 28 agentic-readiness checks (45%). It runs on typo on Apache over HTTPS.
For AI agents, tetra.de's strongest signals are tidy, crawlable markup, fully indexable pages, a visually stable layout, and a clear canonical URL. Approximately 2243 DOM nodes - consider simplifying.
Its main gaps are few clear definitions, no self-contained answer passages, shallow schema coverage, and no speakable schema for voice agents. The weakest area is Structured data; addressing it first would raise this score the most.
