In the App Router, each priority route should have a clear page purpose, unique metadata, a self-canonical, sitemap inclusion where indexable, and structured data that matches visible content.
The useful version of this topic is practical: it should help a buyer make a better website decision, not just define a term.

Use the framework below to turn the topic into a page, brief, audit, or approval checklist.

- Keep canonical URLs stable
- Include only priority indexable pages in the sitemap
- Use robots rules consistently
- Render JSON-LD only for visible supported content
- Check generated routes after build
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.
