FAQ, HowTo, Article, and Product schema are the most effective structured data types for improving AI visibility.
Structured data acts as a layer of clarity for search engines and AI systems. FAQ schema helps define direct answers, while HowTo supports step-based content. Article schema reinforces topical relevance, and Product schema adds context for commercial queries. When used consistently, structured data improves how content is interpreted, indexed, and ultimately selected for AI-generated responses.
