metadataBase points nowhere—or points at preview
Relative social images and canonical URLs resolve incorrectly when metadataBase is absent or set to a vercel.app deployment instead of the production domain.
v0 defaults to Next.js App Router, so most safe SEO repairs should use native metadata exports—not a third-party head library. BulkAudits locates the affected layout or page, changes only the exact metadata node, builds the app, and verifies the rendered route.
Free URL audit. No code changes until you approve a pull request.

Current v0 architecture
v0 defaults to Next.js App Router and creates a working branch from main for each connected chat.
The Next.js App Router already provides static metadata, generateMetadata, file-based Open Graph images, robots, and sitemap conventions. v0’s Git workflow protects main and uses pull requests, which makes verified, reviewable SEO repairs a natural fit.

Server rendering helps discovery, but it does not make metadata correct, unique, or stable by itself.
Relative social images and canonical URLs resolve incorrectly when metadataBase is absent or set to a vercel.app deployment instead of the production domain.
Product, profile, or article routes can render unique content while inheriting the same parent title and description.
Next.js metadata is evaluated by route segment. A child object can replace inherited Open Graph fields and quietly remove the site image or description.
Generated assets may have the wrong path, dimensions, or deployment origin, leaving LinkedIn and WhatsApp with a blank or stale card.
What the pull request changes
No free-form model gets permission to wander through your repository.
Static routes get typed metadata exports. Dynamic routes get a scoped generator only when the required route data is already available safely.
robots, sitemap, and Open Graph assets are placed through native App Router conventions and checked in the production build.
The pull request is created only if the build passes, the finding disappears, and no previously healthy page regresses.
Repository handoff
v0 treats a connected GitHub repository as the source of truth and keeps main protected. BulkAudits adds its own fix branch and pull request to the same review workflow.
Regression detected
A v0 chat replaced metadataBase with a Vercel preview URL. Production-domain fix prepared.

The fix that stays fixed
BulkAudits remembers the exact finding and code node behind a merged repair. A fast static scan checks it after each push; a full audit confirms the live site on schedule.
v0 SEO questions
No. It makes content easier to render, but titles, descriptions, canonicals, social images, structured data, redirects, and sitemap entries can still be missing or wrong.
No. App Router projects use the native Next.js metadata system. Adding a client-side head library would be unnecessary and less reliable.
We can wire deterministic metadata generation when the route already exposes reliable product data. Generated marketing copy remains a review-required draft rather than an automatic merge-ready change.
No. It works through the connected GitHub repository. The fix appears as a normal pull request with a diff, preview, checks, and revert path.
