Rule aeo-7af6bdc343894aec · schema_data · high confidence
Never deliver critical content or schema markup via client-side JavaScript, because none of the main AI crawlers render JavaScript.
Applies to: all
Why this matters
AI crawlers that don't execute JS see only the shell of SPAs; even crawlers that can render face rate limits, timeouts, and headless-browser differences producing incomplete renders.
Implementation
Type: system
Anti-pattern
A React SPA that ranks in Google via client-side injected content and schema while being invisible to AI retrieval.
