Machine-readable brief

CEI Publish — make your catalog machine-readable

CEI Publish renders your verified catalog as a clean, structured surface that AI shopping assistants can read directly. It is the fourth step of the Commerce Eligibility Index: Diagnose (measure readiness), Activate (generate the fixes), Protect (prevent regression), and Publish (expose the verified catalog to the open web).

Why it matters

When ChatGPT, Claude, Gemini, and Perplexity can find, understand, trust, and recommend your products, you reach the fastest-growing, highest-intent channel in commerce.

Where it fits

The Commerce Eligibility Index scores readiness across five pillars — Foundation, Differentiation, Retrieval, Integrity, and Authority — and 16 underlying signals. Publish turns that verified result into a structured surface built for machines.
