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):

• 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

Validation Results

Recommendations

• Missing schema opportunities
• Validation fixes needed
• Generated code for implementation

Error Handling

Deprecated Schema.org rich result types (2024–2026)

Authoritative reference for every rich result Google retired during the 2024–2025 cleanup. Whenever a user asks for one of these, the seo-schema skill must explain that the type is deprecated and either redirect to an active alternative or note that no replacement exists.

Retired June 19, 2025

Announced at Simplifying our Search rich results (developers.google.com/search/blog).

Retired July 31, 2025

Earlier (pre-v2 baseline) retirements

These are listed for completeness so the LLM doesn't suggest them.
