Schema Markup is structured data added to a webpage to help search engines understand its meaning, subject, content type, publisher, and relationships.
What is schema markup?
Quick definition: Schema Markup is code that uses Schema.org vocabulary to describe webpage content in a structured, machine-readable way.
Schema markup can describe organizations, people, articles, services, FAQs, products, events, reviews, breadcrumbs, glossary terms, and other entities. It is commonly implemented using JSON-LD.
For B2B websites, schema markup helps clarify what a page is about, who published it, what entities it discusses, and how it connects to related content.
Why schema markup matters
Schema markup matters because search engines and AI systems need structure. Visible page copy is written for humans. Schema gives machines an additional layer of explicit information.
Schema markup supports Search Engine Optimization, Answer Engine Optimization, Generative Engine Optimization, and Entity Optimization.
It can also make pages eligible for certain enhanced search features, depending on the schema type, content, and Google’s display decisions.
How schema markup works
Schema markup works by assigning recognized types and properties to the entities on a page. For example, a glossary page can use DefinedTerm schema, a collection page can use ItemList, and a question section can use FAQPage.
Useful schema types for B2B websites often include:
- Organization
- Person
- WebSite
- WebPage
- Article
- FAQPage
- BreadcrumbList
- Service
- DefinedTerm
- ItemList
Schema should be accurate, visible-content-aligned, and validated before publishing.

How MSMC approaches schema markup
MSMC uses schema markup as part of a broader SEO/AEO/GEO system. The markup should clarify content, reinforce entity signals, and support internal architecture. It should not be treated as a magic layer added after vague content is published.
