Structured data for AI: LocalBusiness, Service and FAQ, with examples

Structured data is information that readers never see, written in a format machines understand (JSON-LD). It states without ambiguity: “this page is about this business, which offers this service, in this city, at this price”. Here are the three blocks a business needs, with examples ready to adapt.

What Google says about it

For its AI Overviews, Google states that no special markup is required: the usual best practices are enough (Google documentation). Structured data is therefore not a shortcut. It is still useful for search engines to identify your business correctly, and one rule always applies: it must match what is visible on the page.

The three useful blocks

Block	What it describes	Where to put it	Priority
LocalBusiness	The business: name, address, phone, area, opening hours	Home page and contact page	High
Service	A service: name, area served, indicative price	Each service page	High
FAQPage	The questions and answers visible on the page	Pages with an FAQ	Medium

Example 1: the business

{
  "@context": "https://schema.org",
  "@type": "Plumber",
  "name": "Plomberie Durand",
  "url": "https://plomberie-durand.fr",
  "telephone": "+33 3 20 12 34 56",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "12 rue Nationale",
    "postalCode": "59000",
    "addressLocality": "Lille",
    "addressCountry": "FR"
  },
  "areaServed": ["Lille", "Roubaix", "Tourcoing"],
  "openingHours": "Mo-Sa 08:00-19:00"
}

Example 2: a service

{
  "@context": "https://schema.org",
  "@type": "Service",
  "name": "Drain unblocking",
  "provider": { "@type": "Plumber", "name": "Plomberie Durand" },
  "areaServed": "Lille",
  "offers": { "@type": "Offer", "price": "89", "priceCurrency": "EUR" }
}

Example 3: the FAQ

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "How much does drain unblocking cost in Lille?",
      "acceptedAnswer": { "@type": "Answer", "text": "From €89 incl. VAT, free quote." }
    }
  ]
}

Write the structured data in the same language as the visible page: if your page is in French, so is its markup.

Common mistakes

Mistake	Consequence
A phone number different from the one displayed	Conflicting information, less trust
An FAQ marked up but missing from the page	Against Google’s rules
The same Service block copied onto every page	No page stands out
Prices that are never updated	Wrong answers repeated by the assistants

Recoia generates the Service block and the FAQ for each page to create, in the page brief of each opportunity, and compares your page with the ones AI assistants recommend (structured data included).
