Schema Markup Analysis & Generation

Detection

Scan page source for JSON-LD <script type="application/ld+json">
Check for Microdata (itemscope, itemprop)
Check for RDFa (typeof, property)
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:

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