The Business Owner's Plain-English Guide to JSON-LD Schema

We've covered what schema markup is and why it matters before. This post goes deeper on the specific format that matters most: JSON-LD. If you've ever seen the term in a developer's proposal or an SEO audit report and nodded politely while having no idea what it means — this is for you. Understanding it will also help you see why GEO (Generative Engine Optimization) relies so heavily on schema as its infrastructure layer.

Start With Why: What Problem Does Schema Solve?

Google and AI systems read your website the same way a very literal-minded person would — by processing the text on the page. If your homepage says "We help professional speakers build websites that convert," a human reader immediately understands the who, the what, and the why. A search engine or AI system is less certain. Schema markup removes that uncertainty. Instead of leaving Google to infer meaning, schema lets you declare it directly: "This page is about a business. The business is called Brian Kraker Inc. It provides web design services. It is located in Rancho Mission Viejo, CA."

What JSON-LD Actually Is

JSON-LD stands for JavaScript Object Notation for Linked Data. What it looks like in practice is a block of code that lives in the <head> of your web page — invisible to visitors, but fully readable by search engines and AI systems. It doesn't change how your page looks. It only changes how machines understand it.

The Schema Types That Matter Most for Small Businesses

LocalBusiness Schema

The foundational schema for any business with a physical location or service area. It declares your business name, address, phone number, hours, service area, and business type. Without this, Google is guessing at your business details from your page content. With it, you've told Google exactly what it needs to know.

Service Schema

Declares each service you offer as a distinct entity — with its own name, description, provider (you), and area served. This is how you tell Google and AI systems not just that you're a business, but specifically what that business does.

FAQPage Schema

Marks up a question-and-answer section on your page as a structured FAQ. Google uses this to generate FAQ-style rich results in search. AI systems use it to extract specific answers to common questions. We cover this in more depth in our next post on FAQ schema specifically.

Person Schema

For individuals — especially solopreneurs, consultants, speakers, and coaches — Person schema establishes you as a recognized entity with specific attributes: your name, your job title, your employer, your social media profiles, your areas of expertise. This is particularly important for building the kind of entity authority that earns AI citations, as we covered in our guide to how AI assistants decide which businesses to recommend.

Review and AggregateRating Schema

Marks up client testimonials and reviews as structured data, enabling star ratings to appear in search results. This is one of the most visually impactful schema types because it adds star ratings to your search listing — which research consistently shows increases click-through rates significantly.

Why JSON-LD (and Not the Other Schema Formats)

Schema markup can be delivered in three formats: JSON-LD, Microdata, and RDFa. Google recommends JSON-LD because it lives separately from your page's HTML in a self-contained block — meaning it can be updated without touching your page structure. On WordPress, we deliver schema via WPCode, which injects JSON-LD blocks cleanly without touching theme files.

Common Schema Mistakes We Fix in Audits

• Two plugins both outputting schema simultaneously — Yoast SEO generates schema by default; if you also have custom JSON-LD snippets, they conflict
• Schema referencing wrong business information — Outdated phone numbers, old addresses, or incorrect service descriptions
• Missing required fields — Many schema types have required fields that, if absent, cause Google's Rich Results Test to flag the entire block as invalid
• Schema not validated after changes — Updating a plugin or theme can break schema output without any visible change to the page

These are exactly the issues our WordPress SEO audit service identifies and fixes — including resolving the Yoast configuration conflicts covered in our post on whether your Yoast setup is actually correct.
