Structured data (Schema.org, JSON-LD) is the syntactic contract between web publishers and the knowledge graphs that power modern search and large-language-model retrieval. As of April 2026, JSON-LD is present on 53.3% of websites globally (W3Techs). This working paper documents a severe adoption deficit in Indonesia: BPS e-commerce statistics record that only 1.36% of 4.40 million e-commerce operators use a website as their primary sales channel, and practitioner field inspection across Kabekraf-registered creative-economy MSMEs from 2020 to 2026 estimates detailed schema adoption beyond auto-generated Organization markup at approximately one in one thousand Indonesian MSME websites. Using case-study evidence from four author-operated domains, a manual audit of twelve Indonesian listed companies (PT Tbk), and an installation audit of six CMS and plugin combinations, the paper argues that the gap is not a literacy deficit among small business owners but a distribution failure with three reinforcing sources: CMS defaults that ship only basic Organization markup, authoritative documentation available almost exclusively in English, and a competence gap within the pool of certified digital-marketing trainers. The paper proposes a five-level Schema Adoption Ladder, observes that adoption depth correlates inversely with firm size in Indonesia (individual practitioners outperform listed firms), and argues that integrating structured data into Information Systems and Informatics curricula is the highest-leverage intervention available to Indonesian academia in the AI search era.
