Headless Wix removes all schema markup limitations. You can implement any Schema.org type with any level of nesting, connect entities across pages, and build the kind of comprehensive structured data graph that gives you maximum visibility in rich results.
Building a Sitewide Schema Graph
Instead of isolated schema blocks on individual pages, build a connected graph where your Organization entity links to your WebSite, which links to WebPages, which link to Products, Articles, FAQPages and other content types. This graph tells Google exactly how every entity on your site relates to every other entity.

Dynamic Schema Generation from Wix API Data
Write schema generation functions that take Wix API response data and output valid JSON-LD. Create reusable functions for Product schema from eCommerce data, Article schema from blog data, LocalBusiness schema from Wix business info, and FAQ schema from CMS collections.
Schema Types Unique to Headless Implementation
