wp-structured-data

Use when emitting JSON-LD structured data (schema.org) from a WordPress theme or plugin — FAQPage, HowTo, ItemList, Recipe, Event, Product, Review — especially when the data lives in post meta / custom fields the SEO plugin can't see, OR when you must avoid duplicating the schema an SEO plugin (Rank Math, Yoast SEO, SEOPress) already outputs. Covers building the @graph in PHP, escaping with wp_json_encode, printing on wp_head, validating, and coexisting with SEO-plugin graphs. Triggers: \"add FAQ schema\", \"FAQPage JSON-LD\", \"add structured data\", \"schema.org markup WordPress\", \"rich results\", \"HowTo schema\", \"ItemList schema\", \"my FAQ rich result isn't showing\", \"duplicate Article schema\", \"Rank Math already outputs schema\", \"Yoast schema graph\", \"json-ld in head or footer\", \"wp_json_encode schema\", \"schema for custom fields\", \"breadcrumb schema duplicate\", \"validate structured data\". Not for: configuring an SEO plugin's built-in schema UI (use the plugin's own settings); meta tags / OpenGraph (that's SEO-plugin territory); on-page heading/markup SEO.
