Schema Markup Analysis & Generation

\n

When to Use

\n\n

Detection

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

Validation

\n\n

Schema Type Status (as of Feb 2026)

\n

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

\n

ACTIVE (recommend freely):

\n

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

\n

VIDEO & SPECIALIZED (recommend freely):

\n

BroadcastEvent, Clip, SeekToAction, SoftwareSourceCode

\n

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

\n
\n

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.

\n
\n

RESTRICTED (only for specific sites):

\n\n

DEPRECATED (never recommend):

\n\n

Generation

\n

When generating schema for a page:

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