/iblai-marketing-schema-markup
Implement schema.org markup that helps search engines understand content
and unlocks rich results.
Step 0: Context Check
Read .agents/product-marketing-context.md (or .claude/product-marketing-context.md
on older setups) first. Only ask for what isn't there.
Pin down before implementing:
- Page type — what kind of page? Primary content? Possible rich results?
- Current state — any existing schema? Errors? Which rich results already appear?
- Goals — which rich results are you targeting? What's the business value?
Core Principles
- Accuracy first. Schema must accurately represent page content. Don't markup content that doesn't exist. Keep updated when content changes.
- Use JSON-LD. Google recommends JSON-LD. Easier to implement and maintain. Place in
<head> or end of <body>.
- Follow Google's guidelines. Only use markup Google supports. Avoid spam tactics. Review eligibility requirements.
- Validate everything. Test before deploying. Monitor Search Console. Fix errors promptly.

"@graph": [

{ "@type": "WebSite", ... },
{ "@type": "BreadcrumbList", ... }
]
}
Validation and Testing
Tools
Common Errors
Missing required properties — check Google's docs 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 → structured data
Output Format
Schema Implementation
{
"@context": "https://schema.org",
"@type": "...",
}
