Which types matter most
- Organization: legal and brand name, logo, website, and sameAs links to your official profiles. This is the backbone of a consistent brand identity.
- Product with Offer: name, brand, price, currency, availability. Add ratings only if they are real, on-page reviews.
- Article: headline, author, publish and update dates. Dates and authorship are trust signals.
- BreadcrumbList: where the page sits on the site.
- FAQPage: only for questions and answers that are visible on the page. Never mark up hidden text.
Example (Organization)
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Example Skincare",
"url": "https://www.example.com",
"logo": "https://www.example.com/logo.png",
"sameAs": [
"https://www.linkedin.com/company/example-skincare",
"https://www.instagram.com/exampleskincare"
]
}What schema does not do
No published controlled study shows that a particular schema type reliably increases AI citations, so treat claims of fixed percentage lifts with care. Schema cannot fix a page an engine cannot fetch, facts that contradict the rest of the web, or content that does not answer the question. Markup that disagrees with what the page shows can hurt trust.
How ClerAEO measures it
The free scan checks whether a site publishes structured data that engines can read, as part of its AI-readiness checks.
