3Identifies which Google Rich Result types the page is eligible for (FAQ dropdowns, star ratings, breadcrumbs, How-To, etc.).

→Start with the highest-impact schema types: Organization, BreadcrumbList, FAQPage, and Article.
→Ensure all required fields are present — e.g., Article needs headline, author, datePublished, and image.
→Use Google's Rich Results Test to validate your markup after implementation.
→Keep structured data in sync with visible page content — Google penalizes hidden or misleading schema.
