302 리다이렉트

A 302 redirect signals a temporary move, so search engines generally retain the original URL as the intended destination. It suits limited-time sale pages or maintenance notices where restoration is planned. A common implementation mistake is leaving the default 302 in place for a permanent move, creating ambiguity about which URL should be indexed and where signals should consolidate.

Business applications and impact#

Supports temporary campaigns or maintenance while communicating that the original URL remains relevant.

Implementation guidance and considerations#

Use the status code that matches the intended duration; do not rely on 302 for permanent migrations.
