Structured Data (Schema.org): How to Help Google and AI Understand Your Website

Structured data is a “translation” of your website for search engines and AI tools. I explain which types a small business needs, how to add them and how to check they work.

A person looking at your website instantly understands that it's a café in the city centre with opening hours and a menu. Search engines and AI tools have to work that out from the text – and they don't always succeed. Structured data tells them directly, in a language they understand.

What is structured data

It's a short piece of code (usually in JSON-LD format) added to a page that visitors don't see. It describes facts: business name, address, phone, opening hours, prices, article author, questions and answers. It uses the shared Schema.org vocabulary supported by Google, Bing and other services.

Why it's worth it

• Google can show your page in a richer way – for example with a rating, price or date.
• The search engine better understands who you are, where you operate and what you offer.
• AI tools that draw on search results get clear, verifiable facts about your business.

Structured data doesn't guarantee higher rankings, but it removes ambiguity – and that often decides who a search engine or AI recommends.

Which types a small business needs

• LocalBusiness or Organization – name, address, phone, opening hours, logo, social media links. Ideally on the homepage.
• Service or Product – your services or products, for online stores with price and availability.
• FAQPage – frequently asked questions and answers. Useful for people and AI, even though Google now shows them in regular results only for selected websites.
• Article or BlogPosting – an article with author and date.
• BreadcrumbList – breadcrumb navigation showing where a page sits on the website.

How to add it

• WordPress: plugins such as Yoast SEO or Rank Math add the basic types automatically, others can be added in the settings.
• Shoptet and other e-commerce platforms usually generate basic product data themselves – check it.
• Custom websites: the JSON-LD code goes into the page head. On ambidesign.eu, the website generator creates it for every article and the homepage.

How to check it works

1. Google's Rich Results Test (search.google.com/test/rich-results) – shows which types it found and whether they contain errors.
2. The Schema.org validator (validator.schema.org) – checks the whole code.
3. Google Search Console – the Enhancements section shows errors and warnings for the whole website.

The most common mistakes

• data in the code doesn't match what's on the page (different hours, different price)
• reviews or ratings that aren't on the page at all
• the same code copied to every subpage
• outdated data after a change of address or phone number
