Citelayer® adds the Schema markup that makes your content quotable. SEO-TITLE: Schema.org JSON-LD for AI Visibility — WordPress Structured Data Schema.org JSON-LD for AI Visibility Why This Matters When ChatGPT, Perplexity, or Google’s AI Overview answers a question, they don’t just read your text — they parse your structured data first. Schema.org markup tells them exactly who published your content, when it was last updated, and what topics it covers. Without structured data, your content is anonymous text competing with millions of other anonymous pages. Most WordPress sites either ship no JSON-LD at all or rely on basic SEO plugin schemas that lack the signals AI systems look for. Citelayer® generates comprehensive Schema markup designed specifically to make your content identifiable, attributable, and quotable. How It Works Citelayer® injects a Citelayer® generates three schema types, all wrapped together in a single @graph array: Organization Schema Represents your site as a recognized entity. This tells AI systems who is behind the content — critical for attribution and trust signals. { "@type": "Organization", "name": "Your Site Name", "url": "https://example.com", "description": "Your site tagline", "logo": { "@type": "ImageObject", "url": "https://example.com/wp-content/uploads/site-icon.png" }, "knowsAbout": ["WordPress", "SEO", "Content Strategy"], "expertise": ["Technical SEO", "Structured Data"], "sameAs": [ "https://twitter.com/yourhandle", "https://linkedin.com/company/yourcompany", "https://github.com/yourorg" ] } The logo pulls from your WordPress Site Icon (set under Settings → General or Appearance → Customize → Site Identity). The knowsAbout and expertise fields come from Citelayer®’s admin settings. Social profiles populate the sameAs array. WebSite Schema Describes your site as a searchable resource, including a SearchAction that AI systems and search engines use to understand your site’s search functionality. { "@type": "WebSite", "name": "Your Site Name", "url": "https://example.com", "potentialAction": { "@type": "SearchAction", "target": { "@type": "EntryPoint", "urlTemplate": "https://example.com/?s={search_term_string}" }, "query-input": "required name=search_term_string" } } Article / BlogPosting Schema Generated on individual posts and pages. Citelayer® uses BlogPosting for posts and Article for pages — matching what Google’s documentation recommends. { "@type": "BlogPosting", "headline": "Your Post Title", "url": "https://example.com/your-post/", "datePublished": "2025-01-15T10:30:00+00:00", "dateModified": "2025-02-01T14:22:00+00:00", "author": { "@type": "Person", "name": "Jane Author", "url": "https://example.com/author/jane/" }, "publisher": { "@type": "Organization", "name": "Your Site Name", "logo": { "@type": "ImageObject", "url": "https://example.com/wp-content/uploads/site-icon.png" } }, "description": "The post excerpt goes here...", "image": "https://example.com/wp-content/uploads/featured-image.jpg" } The description uses your post excerpt. The image pulls from the featured image. If either is missing, the field is omitted rather than filled with placeholder content. REST API Endpoints Citelayer® exposes three public REST endpoints so you can inspect, debug, or consume schema data programmatically: # Full schema graph (all types combined) GET /wp-json/citelayer/v1/schema # Organization schema only GET /wp-json/citelayer/v1/schema/organization # WebSite schema only GET /wp-json/citelayer/v1/schema/website All three endpoints are public — no authentication required (permission_callback: __return_true). They return JSON with a 200 status code under normal conditions. If Citelayer® detects a multi-family SEO plugin conflict, these endpoints return HTTP 503 Service Unavailable instead of schema data. This prevents serving potentially incorrect structured data when the SEO environment is unstable. Configuration Configure schema output from the Citelayer® settings page in your WordPress admin: Organization Fields knowsAbout — Enter topics as a comma-separated list. Example: WordPress, Technical SEO, Content Strategy, Schema.org expertise — Enter specializations as a comma-separated list. Example: Structured Data Implementation, AI Visibility Optimization Social Profiles Add your profile URLs to populate the sameAs array in the Organization schema: Twitter / X LinkedIn Facebook Instagram GitHub Leave any field empty to exclude it. Only profiles with URLs appear in the output. SEO Plugin Compatibility Mode If you run a compatible SEO plugin, choose how Citelayer® interacts with it: Enhance mode — Citelayer® adds its schema alongside your SEO plugin’s existing output. Use this when your SEO plugin already generates basic schema and you want Citelayer® to fill in the gaps (like knowsAbout, expertise, and richer Article markup). Replace mode — Citelayer® takes full control of JSON-LD output and disables your SEO plugin’s schema generation. Use this when you want one consistent source of structured data. Verification Three ways to confirm your schema is working: 1. View Page Source Open any page on your site, view the HTML source, and search for: You should see the comment followed immediately by a
