## Quick Answer

Check the canonical Netlify production domain for redirects, direct nested routes, real 404 responses, initial and rendered content, unique metadata, canonical URLs, robots.txt, sitemap.xml, response headers, structured data, and private-route boundaries. Review `_redirects` and `netlify.toml` when a rewrite or SPA fallback causes every path to return the same shell. Use prerendering only when the rendering requirement and current Netlify documentation justify it, then verify the output.

## AI Summary

This action page maps public Netlify evidence to routing, build output, framework adapters, redirects, headers, and rendering ownership. It does not assume that hosting on Netlify is itself an SEO advantage or disadvantage.

## Main Explanation

Follow the preferred-domain redirect and inspect both the netlify.app address and custom domain. Confirm only the intended host is canonical. Test apex, www, HTTP, HTTPS, trailing slash, nested routes, old URLs, and a missing URL. Netlify processes routing rules in order, so a broad rewrite can shadow later behavior or turn missing routes into misleading 200 responses.

Compare local build output with deployed initial HTML. Single-page applications can depend on JavaScript for meaningful content, while static generation, server rendering, or deliberate prerendering can expose it earlier. Choose the rendering strategy for the framework and audience, not from a blanket rule. Verify titles, descriptions, headings, links, and structured data on representative routes.

Inspect robots.txt, sitemap.xml, canonical values, `_redirects`, `netlify.toml`, and relevant response headers as one delivery system. Confirm generated files land in the published directory and are not replaced by a catch-all route. Save the deploy identifier with the audit so a result can be tied to the exact release.

Review public and private route boundaries before changing discovery controls. Useful acquisition, documentation, support, and policy routes may be indexable. Account, dashboard, billing, checkout, API, webhook, admin, preview, staging, and user-data routes should stay protected and absent from public sitemaps. robots.txt is not access control.

Map the highest-impact failure to the layer that owns it: route, layout, component, CMS record, metadata generator, sitemap builder, robots output, hosting rule, CDN, or domain configuration. Preserve unrelated behavior, define the acceptance test, implement the smallest correction, publish, and repeat the exact production request.

Use Search Console, crawler logs, analytics, and AI visibility observations for their separate questions. A clean technical check improves eligibility and diagnosis; it does not promise indexing, ranking, citation, referral traffic, or conversion. Keep dates and tested URLs with every later observation so changes can be interpreted honestly.

## Practical Steps

1. Scan the custom production domain.
2. Trace host and path redirects.
3. Test direct and missing routes.
4. Compare initial and rendered output.
5. Inspect robots, sitemap, canonical, and headers.
6. Locate owning Netlify or framework rules.
7. Deploy the smallest correction.
8. Rescan the exact deploy and domain.

## FAQ

### Does Netlify require prerendering for SEO?

Not always. Static or server-rendered output may already be sufficient; inspect the deployed HTML and crawler requirements before adding another layer.

### Can a SPA fallback hurt route diagnosis?

Yes. A broad rewrite can make nonexistent paths return the application shell with status 200, so test missing URLs explicitly.

### Should the netlify.app domain be indexed?

Prefer one controlled canonical domain and consistent redirects when the platform address is only an alternate deployment URL.
