Free Structured Data Audit for E-Commerce

In 2 minutes, find out exactly what’s missing from your product pages — JSON-LD, product identifiers, feeds, policies, and AI crawler access.

Structured data is the foundation of AI visibility. Without it, AI shopping agents can’t identify your products, compare prices, or recommend them to shoppers. MerchantStamp’s free audit checks every critical element and gives you a clear score with actionable fixes.
