What does the validator show you?
It shows what it read as a thing and which fields it attached. For example, you can check whether a name belongs to a fictional product or to the shop that sells it. It recognizes Schema.org data in JSON-LD, RDFa and Microdata and can report syntax mistakes.
Can you use it without publishing the sample?
Use its direct markup input for a made-up example. The URL option fetches a page through the hosted service. Keep private data and unreleased pages out of both inputs. Save the edited example and the relevant result in your own project notes.
Why might a different test report a different result?
The validator focuses on Schema.org’s vocabulary. A search engine can have additional requirements for a particular enhanced result. If that is your goal, check the engine’s eligibility guidance after verifying the fields and the visible page agree.
Which thing owns the name in your example?
Sketch a fictional shop and one fictional product. Each has a different name. Draw where you expect each field to appear in the extracted result.
- Trace the two entitiesKeep the shop and product distinct in the sketch.
- Find the wrong attachmentPut the shop name under the product in a second example. Explain how a person would spot the problem in the field list.
- Keep the corrected exampleSave the intended mapping as the record of what you checked.
