When 302 Redirects Are Correct and When They Aren't

When is a 302 redirect appropriate, and when should it be permanent?

A temporary redirect is suitable when the source address needs to deliver its own content again after a limited period, such as during maintenance or a time-limited test. If the move is permanent, a permanent status should clearly communicate the change of destination.

Documented duration

• Number of temporary redirects without an expiration date, responsible role, or planned restoration of the source address.

• Percentage of internal calls that still use a redirect instead of going directly to the intended destination.

Diagnostic Case: "Permanent Temporary Solution"

A product page redirects to an explanatory availability page during a two-week delivery stoppage and is intended to return to its original location afterward. A temporary rule is appropriate for this; however, a permanently merged product receives a permanent status as its direct successor.

Permanent Temporary Solution

• Permanent Temporary Solution An old 302 redirect remains active for years, while internal links, the sitemap, and teams continue to use the outdated source.

• Incorrect Return Assumption The organization does not plan to restore the source page but nevertheless marks the final switch as temporary.

• Chaining Temporary and permanent rules are added sequentially, causing users and bots to navigate through multiple unnecessary destinations.

Persistent Source

• Documented duration Ownership and expiration date prevent a temporary rule from becoming a permanent infrastructure state unnoticed.

Business-Relevant Target

1. For each redirect, the purpose, future source, target relevance, start time, and expected end date must be documented in writing.

2. Select the appropriate temporary or permanent status and update internal links and the sitemap accordingly.

3. Review temporary rules for the process and regularly check permanent targets for chains, error status, and suitability.
