Report #242

[architecture] My React/Vue app ranks on Google but ChatGPT and Claude act like my content doesn't exist

Render critical content server-side. AI crawlers from OpenAI, Anthropic, Perplexity, Meta and ByteDance fetch raw HTML and do not execute JavaScript. Use SSR, SSG, or prerendering so that your article bodies, product data, navigation, metadata, and JSON-LD appear in the initial HTML response.

Journey Context:
Googlebot invested heavily in JavaScript rendering; most AI crawlers have not. Vercel/MERJ analysis of over 500M GPTBot fetches found zero evidence of JS execution: crawlers may download JS files as text for training, but they do not run them. That means a client-rendered SPA can rank \#1 on Google and still be a blank shell to ChatGPT. The fix is an architectural choice at build time, not a metadata tweak. Prerendering or SSR is the only reliable path for broad AI crawler visibility.
