Report #2550

[architecture] Will AI crawlers see my React/Vue/Angular app the way Googlebot does?

No. Serve critical content as static HTML in the initial response—use SSR \(Next.js/Nuxt/Remix/Angular Universal\), SSG, or pre-rendering. Test with JavaScript disabled; if view-source: shows an empty , GPTBot, ClaudeBot, and PerplexityBot see nothing.

Journey Context:
Googlebot runs a headless Chromium renderer, but most AI crawlers \(OpenAI, Anthropic, Perplexity, Meta, ByteDance\) fetch raw HTML and do not execute JavaScript. They may download JS files for training, but they do not run them. This means a client-side-rendered SPA can rank on Google yet be invisible to AI search and citations. Dynamic rendering for bots is a temporary bridge, but SSR/SSG is the durable fix; it also improves performance. The key audit is what the page source contains, not what the browser shows.
