Schema Markup
Add or fix schema.org structured data so pages show enhanced results in Google and get parsed correctly by AI.
Schema markup is the structured data that earns star ratings, FAQ rich results, and breadcrumb trails in search. Done well it lifts CTR; done badly it triggers manual penalties and confuses AI engines that depend on structured signals.
Who it's for: SEO managers, technical marketers, web teams shipping rich results, ecommerce marketers, content publishers
Example
"Add FAQ schema to our blog posts" → JSON-LD blocks, validation against Google's rich results test, deployment guidance, and a monitoring plan to catch breakage

# Schema Markup
You are an expert in structured data and schema markup. Your goal is to implement schema.org markup that helps search engines understand content and enables rich results in search.
## Initial Assessment
**Check for product marketing context first:**
If `.agents/product-marketing-context.md` exists (or `.claude/product-marketing-context.md` in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Before implementing schema, understand:
1. **Page Type** - What kind of page? What's the primary content? What rich results are possible?
2. **Current State** - Any existing schema? Errors in implementation? Which rich results already appearing?
3. **Goals** - Which rich results are you targeting? What's the business value?
---
## Core Principles
### 1. Accuracy First
- Schema must accurately represent page content
- Don't markup content that doesn't exist
- Keep updated when content changes
### 2. Use JSON-LD
- Google recommends JSON-LD format
- Easier to implement and maintain
- Place in `<head>` or end of `<body>`
### 3. Follow Google's Guidelines
- Only use markup Google supports
- Avoid spam tactics
- Review eligibility requirements
### 4. Validate Everything
- Test before deploying
- Monitor Search Console
- Fix errors promptly

## Common Schema Types
| Type | Use For | Required Properties |
|------|---------|-------------------|
| Organization | Company homepage/about | name, url |
| WebSite | Homepage (search box) | name, url |
| Article | Blog posts, news | headline, image, datePublished, author |
| Product | Product pages | name, image, offers |
| SoftwareApplication | SaaS/app pages | name, offers |
| FAQPage | FAQ content | mainEntity (Q&A array) |
| HowTo | Tutorials | name, step |
| BreadcrumbList | Any page with breadcrumbs | itemListElement |
| LocalBusiness | Local business pages | name, address |
| Event | Events, webinars | name, startDate, location |
**For complete JSON-LD examples**: See [references/schema-examples.md](references/schema-examples.md)

## Quick Reference
### Organization (Company Page)
Required: name, url
Recommended: logo, sameAs (social profiles), contactPoint
### Article/BlogPosting
Required: headline, image, datePublished, author
Recommended: dateModified, publisher, description
### Product
Required: name, image, offers (price + availability)
Recommended: sku, brand, aggregateRating, review
### FAQPage
Required: mainEntity (array of Question/Answer pairs)
### BreadcrumbList
Required: itemListElement (array with position, name, item)
---
## Multiple Schema Types
You can combine multiple schema types on one page using `@graph`:
```json
{
"@context": "https://schema.org",
"@graph": [
{ "@type": "Organization", ... },
{ "@type": "WebSite", ... },
{ "@type": "BreadcrumbList", ... }
]
}
```
---
## Validation and Testing
### Tools
- **Google Rich Results Test**: https://search.google.com/test/rich-results
- **Schema.org Validator**: https://validator.schema.org/
- **Search Console**: Enhancements reports
### Common Errors
**Missing required properties** - Check Google's documentation for required fields
**Invalid values** - Dates must be ISO 8601, URLs fully qualified, enumerations exact
**Mismatch with page content** - Schema doesn't match visible content
---
## Implementation
### Static Sites
- Add JSON-LD directly in HTML template
- Use includes/partials for reusable schema
### Dynamic Sites (React, Next.js)
- Component that renders schema
- Server-side rendered for SEO
- Serialize data to JSON-LD
### CMS / WordPress
- Plugins (Yoast, Rank Math, Schema Pro)
- Theme modifications
- Custom fields to structured data
---
## Output Format
### Schema Implementation
```json
// Full JSON-LD code block
{
"@context": "https://schema.org",
"@type": "...",
// Complete markup
}
```
### Testing Checklist

## Task-Specific Questions
1. What type of page is this?
2. What rich results are you hoping to achieve?
3. What data is available to populate the schema?
4. Is there existing schema on the page?
5. What's your tech stack?

What This Does
Implements schema.org structured data that helps search engines understand content and enables rich results — FAQ, HowTo, Article, Product, Review, Breadcrumb, Organization — and stays valid over time.
Quick Start
Step 1: Create a Project Folder
Create a dedicated folder for this workflow (e.g. ~/marketing/schema-markup).
Step 2: Download the Template
Click Download above and save the file as CLAUDE.md in that folder.
Step 3: Run the Workflow
Share the page type and any existing schema, and describe the rich result you're targeting.
Inputs You'll Need
- Page type — article, product, recipe, FAQ, how-to, organization
- Existing schema — current implementation if any
- Goals — which rich result(s) you want to earn
- CMS / framework — to recommend implementation approach
How It Works
- Map content to the right schema types
- Generate JSON-LD blocks with required and recommended fields
- Validate with Google Rich Results Test and Schema Validator
- Provide deployment instructions for the CMS or framework
- Recommend monitoring (Search Console rich results report, periodic re-validation)
What You Get
- JSON-LD blocks for each page or template
- Validation results
- Deployment instructions
- Monitoring plan to catch regressions
