A Vercel deployment QA pass should check preview URLs, environment variables, forms, analytics, metadata, sitemap, robots, redirects, images, mobile layouts, and production route health.
The useful version of this topic is practical: it should help a buyer make a better website decision, not just define a term.

- Preview URL checklist
- Environment variable list
- Form delivery test
- Route health report
- Post-deploy smoke test
