The Schema Generator drafts JSON-LD from information you provide. It saves typing and syntax work, but the business owner still needs to check every fact before publishing. The generator cannot verify a phone number, service area, opening hours, or customer rating by itself.
Start with facts visible to visitors
Use the business name and address that appear on the page, the service area actually served, and profiles the business controls. Choose the most specific applicable business type when one fits. Google's LocalBusiness guide lists requirements and recommendations for its supported local features. The guidance is not a promise that markup will be displayed.
Do not add a rating or review just because the generator offers a field. Google restricts self-serving review snippets for businesses, and structured data must follow the relevant feature rules. Do not invent a street address for a service-area business or publish hours that staff cannot meet.
Validate the page, not just the pasted block
Copy the markup into the appropriate place on the website, publish the page, and inspect the resulting HTML. Avoid contradictory duplicate declarations from themes and plugins. Use a validator for syntax and Google's Rich Results Test for features Google currently supports. Then compare the markup with what the page visibly says.
Validation is one step. It does not prove Google indexed the page or that ChatGPT, Perplexity, or Gemini used the markup. Google's AI search guidance explicitly says no special schema is required for its AI features.
If you are unsure whether the existing page needs markup at all, start with a Free Report Preview or a narrow GEO Grader check. Fix incorrect visible business information before treating markup as the solution.
