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.
