Structured Data: The Hidden Code That Gets You Cited by AI
There’s invisible code you can add to your website that tells search engines and AI exactly what your business does, where you’re located, what services you offer, and what your customers say about you. It’s called structured data (or schema markup), and it’s one of the most underused tools in home service marketing.
What Is Structured Data?
Structured data is a standardized format (JSON-LD) that you embed in your website’s code. It doesn’t change how your site looks to visitors — but it dramatically changes how machines understand your business.
Think of it as a machine-readable business card. Instead of hoping Google figures out that you’re a plumber in Atlanta, you explicitly tell it.
The Schema Types That Matter for Home Services
LocalBusiness
The foundation. Tells AI: “This is a local business named [X] located at [Y] that serves [Z area].” Includes your name, address, phone, hours, and service area.
Service
Describes each specific service you offer. “This business provides tankless water heater installation as a plumbing service.” One Service schema per service page.
FAQPage
Marks up your FAQ content so AI can extract specific Q&A pairs. When someone asks ChatGPT “How much does a furnace replacement cost?” and your FAQ has the answer, you’re more likely to be cited.
Review / AggregateRating
Tells AI about your review score and volume. “This business has 4.8 stars from 247 reviews.” This can trigger star ratings in search results and strengthens AI trust signals.
Why AI Systems Love Structured Data
AI language models are trained to extract and cite information. Structured data makes extraction trivial — instead of parsing messy HTML and guessing, the AI gets clean, explicit facts. Businesses with structured data are estimated to be 3x more likely to be cited in AI-generated answers.
How to Implement It
Add JSON-LD scripts to your pages. Your developer (or platform) can do this in under an hour. The most impactful schemas for a home service business:
- LocalBusiness on your homepage — Name, address, phone, email, service area, hours
- Service on each service page — Service name, description, provider
- FAQPage on pages with FAQ sections — Question/answer pairs
You can validate your markup with Google’s Rich Results Test to make sure it’s implemented correctly.
