Report #102493

[architecture] My SPA's critical content and meta tags are invisible to AI crawlers because they only see the app shell.

Server-render or statically generate the initial HTML so that content, \`\`, \`\`, canonical links, and JSON-LD are present without executing JavaScript. If you must use a SPA, rely on the History API for routing, return meaningful HTTP status codes, and add \`noindex\` for client-side 404s.

Journey Context:
Googlebot runs Chromium and can render JavaScript, but many AI crawlers and answer engines do not execute JS, and even Google queues rendering, which delays or degrades indexing. Teams often assume hydration is enough, but crawlers may stop at the initial HTML. SSR/SSG removes that risk and improves first paint for humans. For SPAs, avoid hash-fragment routing because Googlebot cannot reliably follow \`href="\#..."\` links; use real \`\` with the History API. Also inject JSON-LD server-side rather than client-side to guarantee it is in the crawled snapshot.
