소프트 404

A soft 404 occurs when an empty page or a not-found message is served with HTTP 200. This creates ambiguity about whether a usable resource exists. Common causes include empty out-of-stock product pages and framework error handlers configured to return success. Review URLs reported as soft 404s in Search Console. If the resource is genuinely absent, return an appropriate 404 or 410 rather than a misleading success response.
