Report #1718

[architecture] My SPA renders fine in Googlebot; why are AI crawlers still missing my content?

Serve critical content, navigation, and metadata in the initial HTML response using server-side rendering \(SSR\) or static site generation \(SSG\). Do not rely on client-side hydration for headings, body copy, canonical links, or internal links. Reserve client-side rendering for authenticated or highly interactive surfaces.

Journey Context:
Googlebot does run JavaScript via its Web Rendering Service, but the render queue introduces delay and not all AI crawlers execute JS at all. Google Search Central still recommends SSR/pre-rendering because 'not all crawlers can execute JavaScript.' The typical mistake is assuming that because Googlebot can render React, every agent can. AI search crawlers often fetch raw HTML only; if your titles, links, and answers live in JS bundles, they are invisible. Tradeoff: SSR adds server/complexity cost but removes the render gap that makes content uncitable. Dynamic rendering is an acceptable temporary bridge, but Google treats it as a workaround, not a long-term architecture.
