Structured Data

Structured data describes page content in machine-readable formats (JSON-LD recommended by Google) using Schema.org vocabulary. On QR code landing pages, it enables rich results (product prices, recipes, breadcrumbs) and improves search engine understanding. Note that FAQ expansions were limited to authoritative government and health sites in August 2023 and then retired from Google Search on May 7, 2026 (status as of August 2026). QR code data itself is structured - vCard for contacts, iCalendar for events, GS1 Digital Link for products - enabling devices to launch appropriate apps after scanning.
