Schema markup for AI search: the structured data guide
Schema markup is structured data, usually in JSON-LD, that describes what a page contains, such as an organisation, article, product, FAQ or event. Google says no special schema is needed to appear in AI Overviews or AI Mode, but accurate structured data helps search engines and AI systems understand your content and entities. Focus on Organization, Article, Product or Service, FAQPage and BreadcrumbList, keep it matched to visible content, and validate it.
What is schema markup?
Schema markup is a shared vocabulary, defined at Schema.org, for describing things on the web: organisations, people, articles, products, services, events, reviews and more. Added to a page, usually as a JSON-LD script, it tells machines explicitly what the page is about instead of leaving them to infer it from the text.
Does schema help with AI search?
Google’s guidance on AI features and your website says there is no special markup required to appear in AI Overviews or AI Mode, and that structured data must match visible content. In practice, schema helps indirectly: it reduces ambiguity about who you are, what you offer and how pages relate, which supports the understanding AI answers depend on. It is a foundation, not a shortcut.
Which schema types matter most?
| Type | Use it for | Key properties |
|---|---|---|
| Organization or LocalBusiness | Your company on the homepage or About page | name, url, logo, sameAs, address, contactPoint |
| Article or BlogPosting | Guides and blog posts | headline, author, datePublished, dateModified |
| Service or Product | What you sell | name, description, offers, areaServed |
| FAQPage | Visible question-and-answer sections | mainEntity with Question and Answer |
| BreadcrumbList | Site structure | itemListElement |
| Person | Authors and experts | name, jobTitle, sameAs |
Why does Organization schema matter so much?
Organization schema with sameAs links to your LinkedIn page, review profiles, directories and social accounts tells systems that these all describe one company. That consistency helps AI tools describe your business accurately, which is the heart of entity SEO.
How do you implement schema properly?
- Audit what you have: Check existing markup with Google’s Rich Results Test and the Schema.org validator.
- Start with Organization: Add it once, site-wide or on the homepage, with sameAs links.
- Add page-level types: Article for posts, Service or Product for offers, FAQPage where questions are visible.
- Use JSON-LD: Google recommends JSON-LD because it is easy to add and maintain.
- Match visible content: Never mark up information users cannot see.
- Validate and monitor: Re-test after releases and watch Search Console enhancement reports.
What mistakes should you avoid?
- Marking up content that is not visible on the page
- Adding FAQ schema to every page regardless of content
- Using conflicting names, addresses or phone numbers across pages
- Leaving out dates and authors on articles
- Copying plugin defaults without checking what they output
- Treating schema as a replacement for good content
What does a good schema set-up include?
Pages with clean schema are also easier to quote, especially when combined with the answer-first structure in our AEO guide and the wider practices in generative engine optimization.
How do you add schema in your CMS?
Most content management systems have plugins or built-in options that output basic schema automatically. Check what they produce, fill in missing fields such as sameAs and author details, and add custom JSON-LD where templates fall short. For custom builds, generate schema from the same data that renders the page, so the two never drift apart. This blog, for example, generates Article, FAQPage and BreadcrumbList markup from each post’s content.
What does Organization schema look like?
A simple Organization block in JSON-LD includes the type, your official name, website URL, logo, a short description and a sameAs list of official profile URLs such as LinkedIn and review sites. LocalBusiness adds address, opening hours and geographic area served. Keep the name and description identical to what appears on your About page and profiles, so every source agrees.
How do you know schema is working?
- No errors or warnings in Google’s Rich Results Test
- Enhancement reports in Search Console show valid items
- Rich results, such as breadcrumbs, appear where eligible
- AI assistants describe your organisation consistently with your markup
Where should a small business start?
Start with three things: Organization or LocalBusiness markup on the homepage with accurate sameAs links, BreadcrumbList across the site, and Article markup with authors and dates on blog posts. These cover identity, structure and authorship, which matter most for how AI systems understand and trust your content. Add Service, Product and FAQPage markup next, page by page, only where the visible content supports it.

Frequently asked questions
Is there special schema for AI Overviews?
No. Google says no special markup is needed; standard structured data still helps understanding.
Which format should I use?
JSON-LD is recommended by Google and is easiest to maintain.
Does FAQ schema still help?
It helps machines understand real FAQ content, though rich result display depends on Google’s current rules.
How do I test my schema?
Use Google’s Rich Results Test and the Schema.org validator.
What is sameAs?
A property that links your organisation to its other official profiles, confirming they describe the same entity.
