Local Business JSON-LD is the machine-readable bridge between your physical service area and map pack results. Without GeoCoordinates, areaServed arrays, and consistent @id entity linking, you are relying on Google to guess your relevance. And Google guesses wrong in densely populated industrial corridors.
LocalBusiness Schema Components
Every location and service page must inject LocalBusiness or Service schema with: name, url, telephone, address (PostalAddress), geo (GeoCoordinates), areaServed, and parent Organization @id reference. This creates an unambiguous entity graph crawlers resolve to specific map queries.
{
"@type": "LocalBusiness",
"geo": {
"@type": "GeoCoordinates",
"latitude": -26.2678,
"longitude": 28.1225
},
"areaServed": ["Alrode", "Wadeville", "Germiston"]
}Advanced Schema SEO Patterns
- FAQPage schema on service pages with real procurement questions
- Service schema with priceRange and provider linkage
- BreadcrumbList for crawl path clarity
- Review schema only for verified, legally compliant testimonials
Implementation in Next.js
Use secureJsonLD() with HTML tag sanitization (substituting < with \u003c) in Server Components. Type schema objects with TypeScript for compile-time validation. Never inject schema client-side. It must be in initial HTML for crawler visibility.
