System Mode: This build skill follows the shared Skill Contract and State Model.
This skill creates Schema.org structured data markup in JSON-LD format to help search engines understand your content and enable rich results in SERPs.
System role: Build layer skill. It turns briefs and signals into assets that other skills can review, publish, and monitor.
When This Must Trigger
Use this when the conversation involves any of these situations — even if the user does not use SEO terminology:
Use this whenever the task needs a shippable asset or transformation that should feed directly into quality review, deployment, or monitoring.

- Creating How-To schema for step-by-step content
- Adding Product schema for e-commerce pages
- Implementing Article schema for blog posts

Create FAQ schema for these questions and answers: [Q&A list]
Specific Schema Types
Create Product schema for [product name] with [details]
Generate LocalBusiness schema for [business name and details]
Audit Existing Schema
Review and improve this schema markup: [existing schema]
Skill Contract
Expected output: a ready-to-use asset or implementation-ready transformation plus a short handoff summary ready for memory/content/.
- Reads: the brief, target keywords, entity inputs, quality constraints, and prior decisions from CLAUDE.md and the shared State Model when available.
- Writes: a user-facing content, metadata, or schema deliverable plus a reusable summary that can be stored under
memory/content/.
- Promotes: approved angles, messaging choices, missing evidence, and publish blockers to
CLAUDE.md, memory/decisions.md, and memory/open-loops.md.
- Next handoff: use the
Next Best Skill below when the asset is ready for review or deployment.
Data Sources
See CONNECTORS.md for tool category placeholders.
With ~~web crawler connected:
Automatically crawl and extract page content (visible text, headings, lists, tables), existing schema markup, page metadata, and structured content elements that map to schema properties.
With manual data only:
Ask the user to provide:
- Page URL or full HTML content
- Page type (article, product, FAQ, how-to, local business, etc.)
- Specific data needed for schema (prices, dates, author info, Q&A pairs, etc.)
- Current schema markup (if optimizing existing)
Proceed with the full workflow using provided data. Note in the output which data is from automated extraction vs. user-provided data.
Instructions
When a user requests schema markup:
-
Identify Content Type and Rich Result Opportunity
Reference the CORE-EEAT Benchmark item O05 (Schema Markup) for content-type to schema mapping:
### CORE-EEAT Schema Mapping (O05)
| Content Type | Required Schema | Conditional Schema |
|-------------|----------------|--------------------|
| Blog (guides) | Article, Breadcrumb | FAQ, HowTo |
| Blog (tools) | Article, Breadcrumb | FAQ, Review |
| Blog (insights) | Article, Breadcrumb | FAQ |
| Alternative | Comparison*, Breadcrumb, FAQ | AggregateRating |
| Best-of | ItemList, Breadcrumb, FAQ | AggregateRating per tool |
| Use-case | WebPage, Breadcrumb, FAQ | — |
| FAQ | FAQPage, Breadcrumb | — |
| Landing | SoftwareApplication, Breadcrumb, FAQ | WebPage |
| Testimonial | Review, Breadcrumb | FAQ, Person |
*Use the mapping above to ensure schema type matches content type (CORE-EEAT O05: Pass criteria).*
### Schema Analysis
**Content Type**: [blog/product/FAQ/how-to/local business/etc.]
**Page URL**: [URL]
**Eligible Rich Results**:
| Rich Result Type | Eligibility | Impact |
|------------------|-------------|--------|
| FAQ | ✅/❌ | High - Expands SERP presence |
| How-To | ✅/❌ | Medium - Shows steps in SERP |
| Product | ✅/❌ | High - Shows price, availability |
| Review | ✅/❌ | High - Shows star ratings |
| Article | ✅/❌ | Medium - Shows publish date, author |
| Breadcrumb | ✅/❌ | Medium - Shows navigation path |
| Video | ✅/❌ | High - Shows video thumbnail |
**Recommended Schema Types**:
1. [Primary schema type] - [reason]
2. [Secondary schema type] - [reason]
-
Generate Schema Markup
Based on the identified content type, generate the appropriate JSON-LD schema. Supported types: FAQPage, HowTo, Article/BlogPosting/NewsArticle, Product, LocalBusiness, Organization, BreadcrumbList, Event, Recipe, and combined multi-type schemas.
Reference: See references/schema-templates.md for complete, copy-ready JSON-LD templates for all schema types with required and optional properties.
For each schema generated, include:
- All required properties for the chosen type
- Rich result preview showing expected SERP appearance
- Notes on which properties are required vs. optional
When combining multiple schema types on one page, wrap them in a JSON array inside a single <script type="application/ld+json"> tag.
-
Provide Implementation and Validation
## Implementation Guide

**Option 1: In HTML <head>**
```html
<head>
<script type="application/ld+json">
[Your JSON-LD schema here]
</script>
</head>
Option 2: Before closing
<script type="application/ld+json">
[Your JSON-LD schema here]
</script>
</body>
Validation Steps
-
~~schema validator

"name": "How long does SEO take to work?",
"acceptedAnswer": {
"@type": "Answer",
"text": "SEO typically takes 3-6 months to show significant results, though this varies based on competition, domain authority, and effort invested. New websites may take 6-12 months, while established sites with existing authority can see improvements in 1-3 months for less competitive keywords."
}
},
{
"@type": "Question",
"name": "Is SEO better than paid advertising?",
"acceptedAnswer": {
"@type": "Answer",
"text": "SEO and paid advertising serve different purposes. SEO provides sustainable, long-term traffic without per-click costs but takes time to build. Paid advertising delivers immediate results but stops when you stop paying. Most successful businesses use both: paid ads for immediate leads and SEO for long-term growth."
}
}
]
}
Implementation: Wrap the above JSON-LD in <script type="application/ld+json">...</script> and place in <head> or before </body>. Test with ~~schema validator.

## Schema Type Quick Reference
| Content Type | Schema Type | Key Properties |
|--------------|-------------|----------------|
| Blog Post | BlogPosting/Article | headline, datePublished, author |
| Product | Product | name, price, availability |
| FAQ | FAQPage | Question, Answer |
| How-To | HowTo | step, totalTime |
| Local Business | LocalBusiness | address, geo, openingHours |
| Recipe | Recipe | ingredients, cookTime |
| Event | Event | startDate, location |
| Video | VideoObject | uploadDate, duration |
| Course | Course | provider, name |
| Review | Review | itemReviewed, ratingValue |
## Tips for Success
1. **Match visible content** - Schema must reflect what users see
2. **Don't spam** - Only add schema for relevant content
3. **Keep updated** - Update dates and prices when they change
4. **Test thoroughly** - Validate before deploying
5. **Monitor Search Console** - Watch for errors and warnings
## Schema Type Decision Tree
> **Reference**: See [references/schema-decision-tree.md](https://github.com/aaron-he-zhu/seo-geo-claude-skills/blob/main/build/schema-markup-generator/references/schema-decision-tree.md) for the full decision tree (content-to-schema mapping), industry-specific recommendations, implementation priority tiers (P0-P4), and validation quick reference.
### Save Results
After delivering content or optimization output to the user, ask:
> "Save these results for future sessions?"
If yes, write a dated summary to `memory/content/YYYY-MM-DD-<topic>.md` containing:
- One-line description of what was created
- Target keyword and content type
- Open loops or items needing review
- Source data references
**Gate check recommended**: Run content-quality-auditor before publishing (PostToolUse hook will remind automatically).
If any findings should influence ongoing strategy, recommend promoting key conclusions to `memory/hot-cache.md`.
