Related Fact-Checks in AEO & GEO Myths
AI chatbots read your schema markup directly to decide what to cite.
Large language models do not parse raw HTML script tags or JSON-LD blocks at inference time when evaluating citation candidates. RAG extraction pipelines convert web pages into clean plain-text passages or markdown blocks before generating text embeddings.
BUSTUse schema markup anyway, since it's a hygiene factor for the rankings AI systems weight indirectly.
Although LLMs do not read JSON-LD code directly during live response generation, structured data remains a vital hygiene factor for modern search engine optimization. Schema markup provides explicit disambiguation for Knowledge Graphs, Organization entities, and Product attributes.
MYTHFAQ schema and FAQ rich results are a durable AEO tactic.
Google announced in May 2026 that it is officially dropping support for FAQ rich results across search results pages, following earlier restrictions that limited FAQ snippets strictly to authoritative government and health sites.
MYTHBuilding an llms.txt boosts AI inclusion.
Despite widespread enthusiasm across digital marketing circles, no major AI search engine or LLM provider has documented or announced the active ingestion of llms.txt files for ranking or citation indexing. Large-scale empirical audits demonstrate that the file format remains virtually unread by active web crawlers.
