Three steps from source to structured data
Review the selected entity type, correct each field, and confirm claims against the page.
Inspect warnings, copy the compiled JSON-LD, then test the published URL with Google's Rich Results Test and Schema.org Validator.
Schema markup is a description, not a ranking trick
Use the most specific type supported by the visible page, connect entities with stable IDs and leave unknown facts out. Organization and WebSite can describe identity without granting a special rich result. Product prices, Event times and JobPosting dates must match what visitors can verify. Do not create a second entity when the site already emits equivalent markup. JSON syntax, Schema.org vocabulary and Google's feature eligibility are different checks.
JSON-LD generator questions
Does valid JSON-LD guarantee a Google rich result?
No. A page must satisfy Google's content and feature-specific policies; even qualifying markup does not guarantee special presentation.
Can the generator analyze a URL for free?
Yes, it can fetch one bounded public HTML page. Rules-based suggestions are available even when the free model allowance is unavailable; browser-only manual editing has no daily limit.
Will it invent ratings, prices, authors or business addresses?
No. The generator leaves unverified facts blank. Review any automated field before publishing.
Are FAQ and HowTo schema useful?
They are valid Schema.org vocabulary, but Google restricts FAQ rich results and no longer displays HowTo rich results. Use them only for matching visible content.
