Redirects of wikipedia.org.
Follow a web address through every redirect, with each status code, where it points next and how long it took.
Looking up…
Permanent or temporary.
- 301 and 308: moved for good. Google treats the new address as the one to show and passes its signals there.
- 302, 303 and 307: moved for now. Google keeps showing the old address.
- 308 and 307 also promise to keep the request method (a form sent with POST stays a POST); 301 and 302 may turn it into a GET.
Chains and loops.
Every redirect is one more round trip before the page loads, and a long chain is easy to break when one address changes. Link straight to the final address, and make each old address redirect in one step. A loop (A to B and back to A) never loads: browsers stop with an error.
The usual setup.
Pick one form of the address, for example https:// without www, and redirect every other form (http://, www.) to it with a single permanent redirect. Then keep that form everywhere: in links, in the sitemap and in canonical tags.
Questions people ask.
What does a redirect checker do?
It follows a web address through every redirect and shows each status code, where it points next and how long it took.
What is the difference between a 301 and a 302 redirect?
301 means moved permanently, 302 moved temporarily. Google treats the target of a 301 as the address to show; with a 302 it keeps showing the old one.
How many redirects are too many?
Each redirect adds a round trip before the page loads. Aim for one step from any old address to the final one.
What is a redirect loop?
A chain that comes back to an address it already visited, so the page never loads and browsers show an error.
