Which Schema.org types actually matter for a Magento store?

For a typical Magento store, six types drive most rich-result eligibility:

• Product, every PDP. Drives star ratings, price snippets, and Google Merchant Listings (free).
• BreadcrumbList, site-wide. Drives the breadcrumb trail in the SERP instead of the raw URL.
• Organization, once per site. Drives the knowledge panel + logo in branded SERPs.
• Article, blog and pillar pages. Drives Article rich result + Top Stories eligibility.
• FAQPage, FAQ-heavy CMS pages. The FAQ accordion in SERP is still supported for some queries (Google quietly demoted it for product/commercial intent in 2023).
• LocalBusiness, for stores with a physical address. Drives the local pack + Google Business Profile cross-checks.

The validator supports all six plus another nine (Person, Service, SoftwareApplication, Course, HowTo, Recipe, Event, Review, DefinedTerm) which Magento stores emit less often but still ship for certain use cases (Service-type pages on Magento + Hyvä service-business stores; Recipe-type for food brands; Course-type for academy/training sites; etc.).
