Quick answer
Structured data is markup, usually schema.org in JSON-LD, that tells machines what a page is about. For AI visibility, mark up your organisation, products, FAQs and articles accurately, keep markup consistent with visible content, and do not expect it to guarantee inclusion in AI answers.
Key takeaways
- Use schema.org JSON-LD and keep it faithful to what visitors can see.
- Prioritise Organization, Product or SoftwareApplication, FAQPage and Article.
- It helps machines understand pages. It does not guarantee a mention.
What should you mark up?
| Type | Use it for | Note |
|---|---|---|
| Organization | Your company: name, logo, contact | One clear entity site wide |
| SoftwareApplication or Product | What you sell | Describe real features only |
| FAQPage | Pages that answer real questions | Marked up questions must be visible on the page |
| Article | Guides and research | Include dates and author or publisher |
| BreadcrumbList | Site structure | Helps machines understand hierarchy |
What should you avoid?
- Markup that describes content not visible on the page.
- Inflated ratings or reviews that you cannot support.
- Copying markup from other sites without adapting it.
Google's guidance
What Google says, and what that means
Google states that you do not need to create new machine-readable files, AI text files or markup to appear in its AI features. Structured data is not a requirement for AI Overviews. It is still worth doing well, because it helps search engines understand what a page is about, it can make a page eligible for certain search result appearances, and other systems that read pages may use it too.
You don't need to create new machine readable files, AI text files, or markup to appear in these features.
The rule that matters most: match the visible page
Google's structured data documentation is consistent on one point. The markup must describe content that visitors can actually see on the page. Marked-up questions must appear in the page text. A rating must reflect real reviews. Markup that describes something the page does not show is at best ignored and at worst treated as misleading.
Types worth implementing, with the reason
| Type | Where to use it | What to include |
|---|---|---|
| Organization | Site-wide, usually on the homepage | Name, logo, URL, contact, official profile links (sameAs) |
| WebSite | Homepage | Name and URL |
| BreadcrumbList | Any page below the homepage | The path from home to the page |
| Article or TechArticle | Guides, blog posts and research | Headline, dates, author or publisher, description |
| FAQPage | Pages with real questions and answers | Only questions visible on the page |
| SoftwareApplication or Product | Product pages | Real features, category and offers, without invented ratings |
A note on FAQPage: Google has narrowed which sites receive FAQ rich results in ordinary search. The markup can still describe a page's content accurately for other systems, but do not add it in the expectation of a specific search appearance.
A testing routine
- 1Validate the markup with a structured data testing tool and fix errors before publishing.
- 2Compare the markup with the visible page and remove anything the visitor cannot see.
- 3Check that the organisation details match on every page and profile.
- 4Recheck after design changes, since templates can silently drop or duplicate markup.
Does structured data get me into AI Overviews?
It helps machines understand a page, but Google does not say it guarantees inclusion. Indexing, eligibility and helpful content matter first.
Which format should I use?
JSON-LD is the format most commonly recommended.
Will schema make AI assistants cite me?
There is no public evidence that schema alone changes whether an assistant names you. It helps machines understand the page, and clear visible text does more for quotability.
Should I use JSON-LD or microdata?
JSON-LD is the format most commonly recommended, because it sits apart from the visible HTML and is easier to maintain.
