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.
## When to Use This Skill
- Adding FAQ schema for expanded SERP presence
- Creating How-To schema for step-by-step content
- Adding Product schema for e-commerce pages
- Implementing Article schema for blog posts
- Adding Local Business schema for location pages
- Creating Review/Rating schema
- Implementing Organization schema for brand presence

## What This Skill Does
1. **Schema Type Selection**: Recommends appropriate schema types
2. **JSON-LD Generation**: Creates valid structured data markup
3. **Property Mapping**: Maps your content to schema properties
4. **Validation Guidance**: Ensures schema meets requirements
5. **Nested Schema**: Handles complex, multi-type schemas
6. **Rich Result Eligibility**: Identifies which rich results you can target
## How to Use
### Generate Schema for Content
```
Generate schema markup for this [content type]: [content/URL]
```
```
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]
```
## Data Sources
> See [CONNECTORS.md](../../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:
1. Page URL or full HTML content
2. Page type (article, product, FAQ, how-to, local business, etc.)
3. Specific data needed for schema (prices, dates, author info, Q&A pairs, etc.)
4. 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:
1. **Identify Content Type and Rich Result Opportunity**
Reference the [CORE-EEAT Benchmark](../../references/core-eeat-benchmark.md) item **O05 (Schema Markup)** for content-type to schema mapping:
```markdown
### 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).*
```
```markdown
### 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]
```
2. **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](./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 `
```
**Option 2: Before closing **
```html
```
### Validation Steps
1. **~~schema validator**
- Test your live URL or paste code
- Check for errors and warnings
2. **Schema.org Validator**
- URL: https://validator.schema.org/
- Validates against Schema.org spec
3. **~~search console**
- Monitor rich results in ~~search console
- Check Enhancements reports for issues
### Validation Checklist
- [ ] JSON syntax is valid (no trailing commas)
- [ ] All required properties present
- [ ] URLs are absolute, not relative
- [ ] Dates are in ISO 8601 format
- [ ] Content matches visible page content
- [ ] No policy violations
```
## Validation Checkpoints
### Input Validation

- [ ] Schema type appropriate for content (Article for blog, Product for e-commerce, etc.)
- [ ] All required data available (author, dates, prices, etc. depending on schema type)
- [ ] Content eligibility for rich results confirmed
### Output Validation

- [ ] All required properties present for chosen schema type
- [ ] URLs are absolute, not relative
- [ ] Dates in ISO 8601 format (YYYY-MM-DDTHH:MM:SS+00:00)

## Example
**User**: "Generate FAQ schema for a page about SEO with 3 questions"
**Output**:
```markdown
## FAQ Schema for SEO Page
### Schema Markup

{
"@context": "https://schema.org",
"@type": "FAQPage",

}

"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."
