Structured data explained: how Google and AI understand your pages
Structured data is a machine-readable summary of a page. What it does for search and AI answers, which types matter for a business, and how to check yours.
The short answer
Structured data is a small block of facts, in a shared vocabulary, placed in a page so machines can read what the page is without guessing. A human sees an article with a title and a date. A machine, reading the structured data, sees: an Article, headline this, published then, updated then, by this Organization, answering these Questions, in this position in the site. Search engines use that for richer results and better understanding. AI assistants use it to know what they are reading before they summarise it.
It is one of the cheapest ways to make a website clearer to the systems that decide whether it is shown.
What it does
| For | Effect |
|---|---|
| Search results | Eligibility for richer displays: breadcrumbs, FAQ dropdowns, product details, organisation panels |
| Search understanding | Clear signals about what the page is, who published it and when it changed |
| AI assistants | A trustworthy summary of the page’s type, date and questions before the text is read; easier citation |
| Your own consistency | One generated description of each page, always in sync with the content |
The types that matter for a business website
- Organization. Who you are: name, legal name, address if relevant, logo, contact points, profiles. Once, site-wide.
- WebSite. The site itself, its name and address, and optionally how its search works.
- BreadcrumbList. Where this page sits in the site. Shows in results and helps machines understand structure.
- Article. For every knowledge or blog page: headline, description, dates published and modified, author and publisher as your Organization, the section it belongs to.
- FAQPage. The questions a page answers, with their answers. Only for questions actually visible on the page.
- Product for stores: name, description, price, availability, reviews if real. LocalBusiness for locations: opening hours, address, phone.
How this knowledge base does it
Every article here carries three blocks, generated automatically from the same source as the page: an Article block with title, description, dates and our Organization as publisher; a BreadcrumbList for its place in the site; and an FAQPage with the questions shown at the bottom of the article. Hub pages carry a CollectionPage block. Because it is generated, it cannot drift from the content, and a new article gets it without anyone remembering to add it.
What this means for you
Ask whoever runs your site which structured data types each page type carries and how they are generated. The right answer names Organization, Breadcrumb, Article or Product, and FAQ where relevant, all produced from the content rather than pasted in. If the answer is “none” or “a plugin, I think”, it is an afternoon of work with a lasting effect on how clearly your site is understood, by search engines and by the assistants your customers now ask first.
Frequently asked questions
Does structured data improve rankings?
Not directly as a ranking factor. It makes pages eligible for richer results, such as FAQ dropdowns and breadcrumbs, and it helps search engines and assistants understand and trust the page, which affects how and where it appears. Treat it as clarity, not as a boost.
How do I see whether my site has it?
View the page source and look for a script block of type application/ld+json, or use Google's Rich Results Test on a page address. Search Console also reports which structured data it found and any errors. If none of those shows anything, your site does not have it.
Can structured data be wrong?
Yes, and it is common: a date that never updates, a rating that does not exist on the page, an organisation name with a typo. Search engines cross-check it against the visible content. Keep it generated from the same source as the page, not typed by hand once and forgotten.
Is this the same as meta tags?
Related but different. Meta tags describe the page for browsers and social previews: title, description, image. Structured data describes the entities on the page in a shared vocabulary that machines can reason about: an article by an organisation with these questions answered. A good page has both, generated from the same content.
