Schema Markup for South Florida Local Businesses

Schema markup is invisible to your customers and mandatory for AI. If your Miami dental practice, med spa, law firm, restaurant, or contractor site doesn't have it in 2026, you are effectively unlisted in ChatGPT, Google AI Overviews, and Gemini. Here's the complete implementation.

The 6 schema types every South Florida business needs

1. LocalBusiness (correct subtype)

{
  "@context": "https://schema.org",
  "@type": "Dentist",
  "name": "Coral Gables Smile Studio",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1234 Ponce de Leon Blvd",
    "addressLocality": "Coral Gables",
    "addressRegion": "FL",
    "postalCode": "33134",
    "addressCountry": "US"
  },
  "geo": { "@type": "GeoCoordinates", "latitude": 25.7217, "longitude": -80.2683 },
  "telephone": "+1-305-555-0100",
  "url": "https://example.com",
  "priceRange": "$",
  "openingHoursSpecification": [{
    "@type": "OpeningHoursSpecification",
    "dayOfWeek": ["Monday","Tuesday","Wednesday","Thursday","Friday"],
    "opens": "08:00", "closes": "17:00"
  }],
  "areaServed": ["Coral Gables","Brickell","Coconut Grove","Miami"]
}

2. FAQPage (20+ questions)

Wrap your homepage or service-page FAQ in FAQPage schema. Every question becomes AI-extractable.

3. AggregateRating (live reviews)

Pull ratingValue and reviewCount from your review platform. Never hardcode; AI engines detect stale data.

4. BreadcrumbList (site-wide)

Adds hierarchy so AI understands site structure. One-liner per page.

5. Service (per offering)

One Service block per core service (Invisalign, Veneers, LASIK, Personal Injury, etc.) with description and priceSpecification.

6. Organization + sameAs

Links your site to your GBP, Yelp, Healthgrades, Facebook, LinkedIn, and industry directories. Critical for AI graph consolidation.

The right subtype per South Florida industry

Dentist → Dentist
Plastic surgeon → MedicalClinic + additionalType "Physician"
Med spa → MedicalSpa (extends MedicalBusiness)
Law firm → Attorney (extends LegalService)
Restaurant → Restaurant (with servesCuisine)
Real estate → RealEstateAgent
HVAC / plumbing / roofing → HomeAndConstructionBusiness (with subtype)
Accountant → AccountingService

Common mistakes to avoid

Using generic LocalBusiness when a specific subtype exists.
Fake AggregateRating (Google now cross-checks with your GBP).
Copy-pasted competitor schema with old addresses.
FAQPage marking questions that don't visibly exist on the page.
Missing sameAs — the single biggest AEO gap in South Florida audits.

Implementing all six correctly typically takes 3–6 hours per site. If that's outside your team's skill set, Seal Global ships the full schema stack, LLMs.txt, and monthly validation for $750/month.

Frequently asked questions

Do South Florida small businesses really need schema markup?

Yes. Schema is now the primary way AI search engines classify and cite local businesses. 92% of ChatGPT citations and 78% of Google AI Overview inclusions come from pages with valid structured data.

What is the difference between LocalBusiness and Organization schema?

LocalBusiness is a subtype of Organization designed for physical-location businesses. Use LocalBusiness (or a subtype like Dentist / Restaurant) as the primary; add Organization only for sameAs and brand-level properties.

Which LocalBusiness subtype should a Miami dentist use?

Dentist (which extends MedicalBusiness). For cosmetic-heavy practices, add "additionalType": "https://schema.org/MedicalClinic". Do not use generic LocalBusiness — you lose specificity and citation weight.

Do I need schema on every page of my website?

No. Homepage: Organization + LocalBusiness. Location pages: LocalBusiness (per branch) + BreadcrumbList. Service pages: Service + FAQPage + BreadcrumbList. Blog: Article + BreadcrumbList. About: AboutPage.

How do I add schema without breaking my WordPress or Shopify site?

JSON-LD in the <head> or before </body> is safe on any platform. WordPress: Rank Math or Yoast handle basics but usually need custom LocalBusiness JSON-LD for South Florida businesses. Shopify: use a custom snippet in theme.liquid.

What is LLMs.txt and does South Florida need it?

LLMs.txt is a plain-text file at /llms.txt that summarizes your business for AI models. It became a de-facto standard in 2025. Every South Florida Seal Global client publishes one by week 1.

How do I validate my schema?

Google's Rich Results Test (search.google.com/test/rich-results) and Schema.org Validator (validator.schema.org). Both should pass with zero errors. Warnings are OK if intentional.

Can Seal Global implement schema on my Miami website?

Yes. Every Seal Global South Florida program includes full schema implementation (LocalBusiness + FAQPage + AggregateRating + BreadcrumbList + Service) plus LLMs.txt — from $750/month with no long-term contract.
