How does the Google Rich Results Tool evaluate nested JSON-LD `@graph` structures?

The Google Rich Results Tool parses the entire `@graph` array as an interconnected network of entities rather than isolated, standalone code blocks. It automatically resolves node references linked via `@id` attributes to validate whether required and recommended properties for supported rich result types are met.

Why does my nested JSON-LD pass validation in the tool but fail to trigger a rich result on Google Search?

Passing technical validation simply confirms that your JSON-LD syntax and property structure are correct, but it does not guarantee search feature placement. Google's display algorithms also enforce quality guidelines, content relevance checks, and minimum visibility rules before rendering rich snippets.

Is it better to use deeply inline-nested JSON-LD objects or flat nodes connected by `@id`?

Using a flattened `@graph` structure with entities connected via explicit `@id` URIs is generally preferred for performance and maintainability. The Google Rich Results Tool processes both approaches effectively, but `@id` referencing prevents duplicate code bloat and minimizes syntax errors in complex schemas.

How can I debug missing or unparsed nested entities in the Rich Results Tool output?

Inspect the "Detected items" section in the test results to verify if Google correctly identified each sub-entity within your graph. If a nested entity is missing, check for broken `@id` link targets, improper property nesting, or invalid `@context` declarations inside child objects.
