What's structured data and why does it matter for Magento?
Structured data (JSON-LD) tells search engines what each page is, a Product, an Article, a FAQ, a BreadcrumbList. Google uses it to render rich results (star ratings, prices, availability, FAQ accordions) directly in search, which can double or triple click-through rate on the same ranking position.
Out of the box, Magento ships no structured data. Adding it correctly, Product on PDP, ItemList on category, FAQPage on FAQ pages, Organization site-wide, Person on author bios, is one of the highest-ROI SEO interventions you can make. We ship it via the Panth_StructuredData module on every project.
