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

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

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

Output

• SCHEMA-REPORT.md

  — detection and validation results

• generated-schema.json

  — ready-to-use JSON-LD snippets

Validation Results

Recommendations

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

Ahrefs Traffic Prioritization

If Ahrefs available: Use ToolSearch with query "+ahrefs" to check availability.

• If Ahrefs MCP tools are returned: fetch

  site-explorer-top-pages

  for the domain to identify highest-traffic pages.
• Add

  ### Schema Priority by Traffic

  section showing which pages receive the most organic traffic and their current schema status — prioritize schema implementation on these pages first.
• Pages with high traffic but missing schema are the highest-impact opportunities.
• If Ahrefs MCP is not available: proceed with static schema analysis only, noting that traffic-based prioritization is unavailable.

Schema Priority by Traffic (when Ahrefs available)

Prioritization logic: pages with >1,000 monthly visits and missing schema are Critical priority. Pages with >500 visits and incomplete schema are High priority.
