Structured data is machine-readable markup added to web pages that describes what a page is, who created it, what it contains and how it relates to other entities — without requiring AI systems to interpret prose.
Why it matters
Structured data does not directly cause AI citations. But it gives systems unambiguous signals about page meaning, authorship, dates and entity relationships — reducing interpretive load and increasing the probability of correct attribution.
For Google AI Overviews and AI Mode specifically, Google states that no special schema.org markup is required to appear. Structured data should not be treated as an AI shortcut. Its role is more fundamental: it makes pages self-describing so that systems can answer who published this, when and on what topic — without parsing prose.
Minimum viable schema for AI Search readiness
Organization
Where
Homepage + About page
Key fields
name, url, logo, sameAs, contactPoint
WebPage / Article
Where
Every content page
Key fields
author, datePublished, dateModified, publisher
Person
Where
Author bio pages
Key fields
name, jobTitle, worksFor, sameAs — links back to articles
FAQPage
Where
Service pages + long-form articles
Key fields
Question + acceptedAnswer pairs
BreadcrumbList
Where
Sitewide
Key fields
itemListElement with position, name, item
LocalBusiness / ProfessionalService
Where
Service businesses
Key fields
address, areaServed, serviceType
The self-describing page test
Can a system answer "who published this, when, and on what topic" by reading only your structured data — without parsing the visible page content? If not, your schema is incomplete. The goal is not to accumulate schema types but to make every important page self-describing.
Common structured data failures
- ✗
Missing author attribution on Article schema
- ✗
Organization schema without sameAs links to verified profiles
- ✗
FAQPage schema on pages where FAQ content is hidden in JavaScript accordions
- ✗
Structured data that does not match the visible page content
- ✗
Person schema without links back to published content
- ✗
No BreadcrumbList — missing site hierarchy signal
