Check a Next.js site

Start with these checks

SEO analyzer

Inspect the public HTML and indexability signals a crawler receives.

Run check

Redirect checker

Validate rewrites, redirects, and final destinations.

Run check

Robots.txt checker

Run check

Common public issues

A route returns a shell or error instead of useful rendered HTML.
Metadata, canonical URLs, or robots directives drift after a route change.
A redirect works locally but points to the wrong production host.

Fix and retest focus

Test the deployed URL with and without a trailing slash when relevant.
Keep canonical, redirect, and sitemap rules consistent with the production host.
Retest after cache invalidation or a deployment rollback.

Good monitoring signals

Key route status and response time
Redirect targets
Rendered metadata and robots directives
Sitemap and robots availability

After the fix

Retest the same public URL and preserve the result as the next baseline. If this is a business-critical route, request monitoring access rather than relying on a one-off check.
