[architecture] My React/Vue/Angular SPA ranks on Google but ChatGPT and Claude see nothing

Server-render critical content into the initial HTML using SSR, SSG, or ISR, or prerender static snapshots for crawlers; never rely on client-side JavaScript for titles, body text, pricing, FAQs, or JSON-LD schema.

Journey Context:
Googlebot runs a headless Chromium engine and executes JavaScript, but OpenAI, Anthropic, Perplexity, and Meta crawlers fetch only the raw initial HTML. Vercel's analysis of over 500 million GPTBot requests found zero evidence of JavaScript execution. An SPA that returns an empty \`\` is effectively blank to every major AI crawler except Google. Prerender services are a lighter alternative to SSR but introduce snapshot-staleness maintenance. The durable fix is an SSR framework such as Next.js, Nuxt, or SvelteKit. The cheapest diagnostic is \`curl -s https://yoursite.com\` or disabling JavaScript in a browser.
