SEO Schema

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 May 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.

NO RICH RESULTS — KEEP FOR AI:

• FAQPage: Google retired FAQ rich results for ALL sites on May 7, 2026 (supersedes the Aug 2023 gov/health restriction). No SERP feature anymore — but flag existing FAQPage at Info (not Critical), since the markup still aids AI Mode / AI Overviews entity resolution. For genuine user Q&A pages, use QAPage.

DEPRECATED (never recommend):

Read references/deprecated-types-2024-2026.md before advising on deprecated rich result types or replacements.

• 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
