Report #103056

[architecture] My SPA renders fine in the browser, but AI and search crawlers miss the content.

Serve essential content, metadata, \`\`, canonical links, and structured data as static HTML or server-side rendered markup. If you must hydrate client-side, use prerendering or dynamic rendering for known crawlers, and verify by fetching your page with a crawler user-agent to ensure the critical facts appear in the first response body.

Journey Context:
While Googlebot can execute JavaScript, it does so in a delayed, resource-constrained rendering queue; most specialized AI crawlers are even less likely to run your bundle. The safe default is 'HTML first.' Google explicitly recommends server-side or pre-rendering because it is faster for users and crawlers and not all bots can run JavaScript. Pitfalls include hash-fragment routing \(Googlebot can't reliably resolve \`\#/paths\`\), soft 404s in SPAs, and lazy-loaded content that never appears in the rendered HTML. The verification step matters: curl with a crawler UA and look at the body, don't just trust the browser.
