What is the difference between a 301 and a 302 redirect?
A 301 redirect tells search engines an address has moved permanently and transfers its ranking signals to the new address, while a 302 redirect signals a temporary move and keeps those signals on the original address; tlnk.kr uses 302.

When is a 301 redirect used?
A 301 means "this address will always point there from now on." It is used when a site moves domains permanently and the old address will never be reused, and search engines transfer the ranking signals the old address had built up to the new one.
If a shortener service used 301, search engines could start treating the short link as the destination's permanent replacement, reducing the flexibility to point it somewhere else later.
How is a 302 redirect different?
A 302 means "it currently points there, but this may be temporary." Search engines keep the ranking signals on the original address and do not treat the short link as a permanent replacement for the destination.
Because a tlnk.kr short link's destination can be changed at any time and never expires automatically, 302 matches how the link actually behaves. Changing the destination is covered in the management screen described in reading short link click stats.
Why does tlnk.kr specifically use 302?
First, changing a link's destination does not permanently hand ranking to the old destination, so moving it elsewhere later stays easy. Second, a link that pauses automatically when its target is unreachable and resumes once it recovers matches the "temporary move" meaning of 302 as well.
Third, human visitors may see a Coupang Partners ad banner for about 2 seconds before the actual redirect, and 302 avoids search engines misreading that intermediate step; search and preview bots are redirected immediately with no banner.
Does the redirect type relate to the safety checks?
Yes. tlnk.kr rechecks each destination every day, and it rechecks every hop when a redirect chains through multiple steps. Since destinations and their status (active or paused) can change over time, 302 describes tlnk.kr's actual behavior to search engines more accurately than a permanent 301 would.
In short, 302 gives the link owner the freedom to change destinations while giving search engines an accurate signal about what is happening.
Frequently asked questions
Is 302 bad for SEO?
If you use a short link for human clicks on social media or in messages rather than as the canonical search-facing URL for your content, the choice of 302 has little practical impact. If you want your content's own address to be what search engines index, use the original URL directly instead.
Does changing a link's destination reset its previous click stats?
No. A short link's click stats keep accumulating even after its destination changes. It is a good idea to keep your own note of which destination was active during which period.
Can I choose 301 instead of 302 for a specific link?
tlnk.kr applies 302 to every short link uniformly; there is no per-link option to choose 301 instead.
Do search bots also see the ad banner?
No. Search engine and preview bots are redirected straight to the destination with no banner; the banner may only appear for about 2 seconds when a human visitor opens the link.
