301 vs 302 in Affiliate Funnels

Status code choices impact cache behavior, indexability, and data consistency across redirect hops.

When 301 is right

1. Destination is permanently replaced and unlikely to change again.
2. You want search engines and browsers to update canonical target over time.
3. Campaign logic is stable and does not rely on daily geo/device switching.

When 302 or 307 is safer

1. Offers rotate frequently by inventory or partner availability.
2. Routing rules vary by geography, time window, or audience segment.
3. You need flexibility while preserving the original URL as temporary source.

Fast validation workflow

1. Test with multiple user agents to detect inconsistent status behavior.
2. Compare hop latency and final URL for each profile.
3. Confirm query parameters remain intact through the full chain.

FAQ

Does a 301 redirect hurt affiliate tracking?

A 301 does not inherently break tracking, but caching and URL rewrites can hide parameter issues. Validate click IDs and UTM keys after deployment.

When should I use 302 instead of 301?

Use 302 for temporary routing logic, such as offer rotation, geo testing, or short-term traffic distribution changes.

Is 307 better than 302 for redirects?

307 is safer when you need strict method preservation. 302 remains common for temporary browser redirects in ad operations.
