What a redirect loop is

A redirect loop is when URL A redirects to URL B and URL B redirects back to URL A (or the chain cycles).

Common loop patterns:

• http ↔ https
• www ↔ apex
• trailing slash ↔ no slash
• locale redirects that depend on cookies

The 10-minute diagnosis

1. Test the URL with a clean request (no cookies).
2. Note every hop until it fails.
3. Check whether the destination differs by host, slash, or protocol.

Fix checklist

1. Pick one canonical pattern (host + protocol + slash).
2. Make sure the canonical URL returns 200 and does not redirect.
3. Collapse the loop into a single deterministic redirect.
4. Avoid chains (one hop is the goal).

Validation

• GSC URL Inspection: final URL should be stable.
• The page should render and return 200 for Googlebot.
