What Is Structured Data and Why Does Your Website Need It?
Structured data (JSON-LD) helps Google and AI systems understand what your website is about. Here's what it is, what it does, and how to add it without a developer.
What Structured Data Actually Is
Structured data is a standardised way of providing explicit information about your webpage to search engines and AI systems — information that isn't visible to visitors but is read by machines. The most common format is JSON-LD (JavaScript Object Notation for Linked Data), a small block of code added to your page's HTML that describes its content in a structured way.
Think of it as a label on a box. The box (your webpage) might contain useful things, but without a label, a machine has to open it and guess what's inside. Structured data is the label.
What Structured Data Enables
Google Rich Results
Pages with structured data become eligible for rich results in Google Search — star ratings, FAQ dropdowns, product information, event dates, and more appearing directly in the search result. These results have significantly higher click-through rates than standard blue links.
AI System Citations
ChatGPT, Perplexity, and Google's AI Overviews all use structured data signals to identify and categorise content. Pages with Organisation, Service, Product, or FAQ schema are more reliably cited by AI systems than pages without it — because the AI can read the label rather than having to guess.
Knowledge Panel Information
When someone searches your business name, the information panel on the right side of Google's results draws heavily from structured data. Business name, logo, website, social profiles, and description all flow from Organisation schema when implemented correctly.
The Most Valuable Schema Types for Small Businesses
- Organization — your business name, URL, logo, contact info, social profiles. Should be on every page.
- LocalBusiness — for businesses with a physical location: address, opening hours, geo coordinates.
- Service — describes your service offerings, pricing, and target audience.
- FAQ — marks up question and answer content for both rich results and AI citation.
- BreadcrumbList — helps search engines understand your site structure.
How to Add JSON-LD Without a Developer
JSON-LD is added inside a <script type="application/ld+json"> tag in your page's HTML. Most CMS platforms (WordPress, Squarespace, Wix) have plugins or settings that add basic schema automatically. For custom-built sites, it's a one-time task for a developer.
Google's Rich Results Test (search.google.com/test/rich-results) lets you check any URL to see what structured data it currently has and whether it's valid. Running a free website audit will also surface missing schema as part of the AI visibility and SEO sections.
