Structured data for local businesses gives search engines explicit details about your hours, location, and services rather than leaving them to infer it.
Cover the Core Fields
Business name, address, phone number, hours, and category should all be marked up consistently with your actual live information.
Keep It in Sync With Your Profile
Structured data that contradicts your business profile listing creates confusion that search engines are likely to resolve in your disfavor.
Validate Regularly
Business hours and details change more often than most site owners remember to update in their schema markup, so check periodically.
Next step: Use the Get Source Code of Webpage to confirm your local schema markup matches what's actually displayed.
