Summary
E1043: Walking through a brand new study from Ahrefs that tested one of the most repeated claims in SEO: "Add schema to get cited more by AI." The data does not support that claim.

The theory sounded logical: machines need machine-readable data, so schema must help AI systems cite your content. But when you isolate the variable and control for authority, content quality, and existing citation levels, the effect disappears. We also discuss: - Why 53% of AI-cited pages have schema (and why that doesn't prove causation) - How correlation misleads SEOs - Why technically sophisticated sites tend to have both schema and strong authority signals - A related experiment showing major AI systems ignore JSON-LD during live retrieval - What actually moves the needle for AI visibility If you're: - Paying an agency for schema to improve AI citations - Offering schema implementation as an AI visibility service - Trying to future-proof your SEO strategy for LLM search This episode is worth your time.
