Start with the rendered page
Page content, metadata, and URLs should describe the same page. In a Next.js app, that means checking the HTML a visitor or crawler receives, alongside the content shown after navigation.
A title alone cannot explain a page whose main content is missing or whose canonical URL points somewhere else.
Review the parts together
For an indexable page, check:
- The main heading and useful content are available in the rendered HTML.
- The title and description are specific to that page.
- The canonical URL identifies the version you want indexed.
- Language alternates point to genuine translations.
- Shared previews use the same title and description.
For example, a Persian page should use its Persian title and name. An English article inside Persian navigation can keep English metadata and point to its English canonical version.
Include this in release review
Check both a direct page load and navigation from another page. Shared layouts and metadata defaults can hide differences between the two.
