Google recommends JSON-LD as the easiest format to maintain. Place scripts in <head> or early <body> with valid JSON syntax.
Start with Organization and WebSite
Add Organization schema with name, url, and logo. WebSite schema with potentialAction enables sitelinks search box eligibility in Google.
Use FAQPage for real FAQs only
FAQ schema must reflect visible FAQ content on the page. Misleading FAQ markup can result in manual actions and rich result loss.
