name: seo-schema description: > Detect, validate, and generate Schema.org structured data. JSON-LD format preferred. Use when user says "schema", "structured data", "rich results", "JSON-LD", or "markup".

Schema Markup Analysis & Generation

Detection

1. •Scan page source for JSON-LD <script type="application/ld+json">
2. •Check for Microdata (itemscope, itemprop)
3. •Check for RDFa (typeof, property)
4. •Always recommend JSON-LD as primary format (Google's stated preference)

Validation

• •Check required properties per schema type
• •Validate against Google's supported rich result types
• •Test for common errors:
  • •Missing @context
  • •Invalid @type
  • •Wrong data types
  • •Placeholder text
  • •Relative URLs (should be absolute)
  • •Invalid date formats
• •Flag deprecated types (see below)

Schema Type Status (as of Feb 2026)

Read references/schema-types.md for the full list. Key rules:

ACTIVE — recommend freely:

Organization, LocalBusiness, SoftwareApplication, WebApplication, Product (with Certification markup as of April 2025), ProductGroup, Offer, Service, Article, BlogPosting, NewsArticle, Review, AggregateRating, BreadcrumbList, WebSite, WebPage, Person, ProfilePage, ContactPage, VideoObject, ImageObject, Event, JobPosting, Course, DiscussionForumPosting

VIDEO & SPECIALIZED — recommend freely:

BroadcastEvent, Clip, SeekToAction, SoftwareSourceCode

See schema/templates.json for ready-to-use JSON-LD templates for these types.

JSON-LD and JavaScript rendering: Per Google's December 2025 JS SEO guidance, structured data injected via JavaScript may face delayed processing. For time-sensitive markup (especially Product, Offer), include JSON-LD in the initial server-rendered HTML.

RESTRICTED — only for specific sites:

• •FAQ: ONLY for government and healthcare authority sites (restricted Aug 2023)

DEPRECATED — never recommend:

• •HowTo: Rich results removed September 2023
• •SpecialAnnouncement: Deprecated July 31, 2025
• •CourseInfo, EstimatedSalary, LearningVideo: Retired June 2025
• •ClaimReview: Retired from rich results June 2025
• •VehicleListing: Retired from rich results June 2025
• •Practice Problem: Retired from rich results late 2025
• •Dataset: Retired from rich results late 2025
• •Book Actions: Deprecated then reversed — still functional as of Feb 2026 (historical note)

Generation

When generating schema for a page:

1. •Identify page type from content analysis
2. •Select appropriate schema type(s)
3. •Generate valid JSON-LD with all required + recommended properties
4. •Include only truthful, verifiable data — use placeholders clearly marked for user to fill
5. •Validate output before presenting
