# How to implement JSON-LD structured data in Next.js App Router for multiple page types?

I'm building a business website in Next.js (App Router) and want to add JSON-LD structured data across different page types: Organization on all pages, Service on service pages, and BlogPosting on blog posts.

My current approach is a reusable base schema (Organization and WebSite) in the root layout, plus page-specific schema injected in each page component:

export default function Page() {\
const schema = {\
"@context": "https://schema.org",\
"@type": "Service",\
name: "SEO Services",\
provider: { "@id": "https://example.com/#organization" },\
};

return (\
<>\
<script\
type="application/ld+json"\
dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }}\
/>\
{/* page content */}\
</>\
);\
}

Questions:\
1. Is this the recommended way to inject JSON-LD in the App Router, or is there a cleaner pattern?\
2. How should I link page-level schema to the base Organization schema using @id so Google treats them as one entity?\
3. Is there any risk of duplicate or conflicting schema when both the layout and the page output JSON-LD?\
4. What is the best way to validate it at scale (Rich Results Test, Search Console, or automated checks in CI)?

Any examples or best practices would be appreciated.
