Direct answer
A Next.js SEO checklist should cover server-rendered content, unique metadata, canonical URLs, Open Graph, sitemap, robots, schema that matches visible content, internal links, and route QA.
The useful version of this topic is practical: it should help a buyer make a better website decision, not just define a term.
Practical framework
Use the framework below to turn the topic into a page, brief, audit, or approval checklist.
- Use route metadata or metadata helpers
- Create self-canonicals for priority routes
- Generate sitemap and robots routes
- Render important copy and links in HTML
- Use FAQ schema only with visible FAQs
- Run route and browser checks before launch
Method proof to prepare
When public client proof is not available, method proof can still make the decision inspectable without inventing outcomes, reviews, awards, or rankings.
- Metadata map
- Sitemap output
- Structured data inspection
- Rendered HTML spot check
- Playwright route checks
