# Structured Data / Schema Markup

Machine-readable code using schema.org vocabulary that helps search engines and AI understand your content.

## Definition

Structured data (schema markup) is JSON-LD code using the schema.org vocabulary that helps search engines and AI systems understand the meaning and relationships within your content. It''s the bridge between what humans read on your page and what machines can interpret.

For example, you might write "John Smith is the CEO of Acme Corp" on your About page. Without schema markup, Google knows those are words on a page. With schema markup, Google knows John Smith is a Person, his role is CEO, and the organization is Acme Corp. This precision matters for rich results, knowledge panels, and AI citation.

Common schema types for B2B companies include Organization, FAQ, Article, Service, Review, and HowTo. For a glossary like this, DefinedTerm schema tells AI systems these are authoritative definitions.

Structured data pairs naturally with [GEO](/glossary/geo-generative-engine-optimization) and [AEO](/glossary/aeo-answer-engine-optimization) strategies. It''s also complementary to [llms.txt](/glossary/llmstxt) — schema markup makes individual pages machine-readable, while llms.txt makes your entire site structure machine-navigable.

## Why It Matters for Middle Market Companies

Structured data is the bridge between your human-readable content and machine understanding. It''s one of the most underused but high-impact SEO and AI strategies for mid-size companies.

Here''s what it gets you: rich search results (stars, FAQs, pricing info right in Google), better Google Knowledge Panel representation, improved eligibility for featured snippets, and — increasingly — better AI citation of your content.

Most mid-size company websites have little to no schema markup. That means you''re leaving performance on the table with every page you publish. Adding structured data to your existing content can improve click-through rates 20-30% without changing a word of copy.

We implement structured data as part of every website and content project in our [AI enablement services](/services/ai-enablement). [Book a strategy session](/book-audit) to see what''s missing from your current setup.
