How does JSON-LD Schema affect citation rates in GEO optimization?

JSON-LD Schema is the 'machine-readable language' that helps generative AI interpret a page's meaning accurately and use it in answers. In 238lab's GEO expansion phase, one of the core tasks is 'JSON-LD Schema LLM optimization'.

Schema Types That Matter Most in GEO

• FAQ Schema: The question-answer structure makes content easy to cite directly in AI responses
• HowTo Schema: Structures step-by-step guides, making them a go-to source for 'how do I...?' answers
• Article / NewsArticle: Reinforces E-E-A-T signals through author, publish date, and topic information
• Product / Service: Structures product and service attributes, pricing, and reviews to serve as a source for AI comparison answers
• Organization / Person: Defines company and expert entities, becoming the key source for brand and person queries
• Review / AggregateRating: Lets AI use reviews and ratings as trust signals
• Breadcrumb / WebSite: Defines site structure and search functionality

Schema Design from an LLM Optimization Perspective

• We do not simply apply schema. We structure attributes in a way that makes them easy for AI to cite
• We explicitly connect relationships between entities (Organization-Person-Product)
• We match schema 100% with actual page content to prevent spam signals
• We always validate with Google Rich Result Test and Schema.org Validator

238lab's Scope of Work

• Diagnose currently applied schema and correct errors
• Design templates by page type
• Provide JSON-LD code samples and support implementation by your dev team
• Apply schema directly on standardized platform solutions, and write technical specifications for dev teams on custom-built sites
• Monitor whether Rich Results appear after implementation

Schema is not a one-time task. It must be managed continuously as services change and content is added. Schema maintenance is included by default in managed services and custom projects.
