Production URL
Identify the production deployment and custom domain. Keep preview and branch URLs out of canonicals, sitemaps and public internal links.

v0 and Vercel SEO: verify the production project, not the preview
v0 can publish projects to Vercel, but deployment success is not search validation. Confirm the canonical domain, framework output, route metadata, crawlable links, status codes and discovery files on the production deployment.
Platform fact, then production verification: v0 documents production publishing to Vercel, while Next.js documents metadata APIs and special metadata files. The exact checks still depend on the generated project and its production configuration.
Production-first diagnostic
Rendering path
Record whether each route is static, server-rendered or client-rendered. Compare the initial HTML response with the rendered DOM.
Next.js metadata
For Next.js projects, inspect route metadata objects or generateMetadata output, metadataBase and file conventions such as robots and sitemap.
Dynamic routes
Confirm route parameters build or resolve in production, return 200 only for real content, and produce distinct titles, descriptions and canonicals.
Links and navigation
Use ordinary anchors for important routes. Verify mobile navigation and generated cards do not rely only on JavaScript click handlers.
Index controls
Check robots.txt, meta/X-Robots-Tag, sitemap URLs and canonical consistency on the final host before requesting indexing.
Separate preview convenience from canonical production
Vercel preview URLs are useful for review, but public search signals should converge on the chosen production domain. Use redirects where appropriate, set absolute canonical and social URLs from the production base, and ensure the sitemap contains only canonical production URLs.
When a custom domain is attached, retest both the domain and the original vercel.app host. Do not assume the platform automatically expresses your preferred canonical in application metadata.
Use Next.js metadata deliberately
For Next.js App Router projects, static metadata and dynamic generateMetadata can create titles, descriptions, canonicals and social fields. File conventions can produce robots.txt and sitemap.xml. Confirm the resolved output for every template and dynamic route; a correct root layout does not guarantee unique child-route metadata.
Keep the document head valid and avoid competing tags from multiple components, scripts or integrations. Structured data should be valid JSON-LD and match the visible page.
Test routing and status behavior
Open deep routes directly, refresh them, and request nonexistent variants. Real pages should return their intended content and status; missing records should not return a generic 200 app shell. Link to indexable routes using real anchors and include only canonical, useful URLs in the sitemap.
Evidence to record before recommending a fix
| Layer | Record | Do not infer |
|---|---|---|
| HTTP | Final URL, redirects, status, headers and response type | That a 200 URL is indexed or useful |
| Source and render | Title, H1, text, links and canonical before/after rendering | That every crawler processes JavaScript alike |
| Discovery | Internal anchors, robots rules and canonical sitemap URLs | That sitemap submission guarantees indexing |
| Search | URL Inspection state, impressions, clicks and queries over time | That one technical change caused a ranking movement |
Questions founders and developers ask
Does publishing from v0 make a site SEO-ready?
It makes the project publicly deployable. Search readiness still depends on the generated framework, route output, content, metadata, links and index controls.
Should the vercel.app URL be indexed?
Usually a branded custom domain should be the canonical public host. Test redirects and canonical tags rather than assuming duplicate deployment URLs are consolidated automatically.
Does Next.js metadata guarantee indexing?
No. It helps provide machine-readable page information, but discovery, crawl access, canonicalization, content quality and search demand remain separate.
Can client components rank?
They can be rendered, but implementation details and other crawlers vary. Verify important content and links in the production response and rendered output.
Primary documentation reviewed
Use the manual source and indexability checklist, follow the cross-platform JavaScript SEO guide, diagnose cases where only the homepage is indexed, review how VibeToRank diagnoses AI-built sites, or compare the symptoms in why AI-built websites do not rank.
Need the deployed routes checked?
We inspect the production response, rendered output, routes, metadata, canonicals and discovery signals before recommending implementation.
