Schema Markup for AI SEO: A Complete 2026 Guide

Schema markup is structured data that helps search engines and AI systems understand your content. In 2026, it's more important than ever for AI SEO.

What is Schema Markup?

Schema markup is code you add to your website that tells search engines what your content means. Instead of just seeing text, search engines understand:

• What type of content it is (article, product, business, etc.)
• Who created it
• When it was published
• What it's about
• Who it's for

Why Schema Markup Matters for AI SEO

AI systems like ChatGPT, Perplexity, and Google's AI Overviews use schema markup to:

• Understand what your business does
• Extract key information (name, address, phone)
• Verify your credibility and authority
• Find relevant content to cite

Without schema markup, AI systems have to guess what your content means. With it, you're telling them explicitly.
