Fetch a URL, find meta gaps, rewrite title/description/OG suggestions, and preview an ImageResponse card.
Run this experiment yourself
Demos are not embedded on this site. Deploy a standalone copy on Vercel or run the experiment app locally.
Local development

Then open http://localhost:3010.
This is an experimental demo. Use it as a starting point for your own projects.
SEO Meta Auditor fetches a page (capped), extracts title/description/canonical/OG tags, computes local gaps, rewrites suggestions via generateObject, and exposes /api/og for an ImageResponse preview.
Features
- Meta extraction + local gaps – title/description/canonical/OG
- Rewritten suggestions – title / description / OG fields
- ImageResponse OG –
/api/og?title=&description=
Server Reference
POST /api/audit
{ "url": "https://vercel.com/docs" }| Status | Cause |
|---|---|
503 | No AI provider |
400 | Validation / upstream / empty input |
GET /api/og
Query: title, description. Returns a 1200×630 PNG via ImageResponse.
Implementation Details
Pure helpers in logic.ts
Caps, parsers, and clamps live in the experiment folder and are covered by logic.test.ts.
Route Handler
POST /api/audit validates input, applies fetch/parse limits where relevant, then returns JSON from generateObject.
Use Cases
- Learn composition patterns for this lab’s stack.
- Prototype before wiring production auth and quotas.
- Deploy the standalone app as a reference implementation.
Limitations
- Demo-scale caps on input size and output counts.
- No auth / rate limits on public deploys.
- Model quality depends on input clarity.
- Treat outputs as drafts, not production truth.
Use in your project
Copy the Route Handler and logic.ts helpers from apps/experiments/seo-meta-auditor/. Wire your own persistence and auth as needed.
