How to add JSON-LD in Next.js

1. 01

   Generate route-specific data

   Build the object from the same data used by the visible page.

2. 02

   Use absolute canonical identifiers

   Create stable @id and URL values.

3. 03

   Serialize into an application/ld+json script

   Use JSON.stringify and framework-safe output handling.

4. 04

   Review static and dynamic routes

   Test server-rendered, statically generated, and client-updated pages.

5. 05

   Validate after deployment

   Confirm the final HTML, caching, and canonical host.

Validate the final production output in layers: JSON syntax, Schema.org vocabulary, current feature-specific requirements, visible content, and crawl access.

• Define the purpose and expected result of json-ld in next.js.
• Capture the current state using visible entities, page purpose, JSON-LD graphs, identifiers, relationships, required properties, and consumer-specific eligibility.
• Identify the source template, component, plugin, content owner, and release path that controls the output.
• Prepare a test case, approval path, backup or rollback method, and post-release verification plan.

• Parse the deployed json-ld, validate the graph, compare it with visible content, and test any target consumer requirements.
• Check representative page types and edge cases instead of confirming only the example used during implementation.
• Confirm the change did not create publishing properties that are unsupported, hidden, stale, or inconsistent with visible content.
• Record the implementation date, owner, release reference, evidence, and next review trigger.
