Status

301 Moved Permanently

What is a 301 Moved Permanently HTTP response?

A 301 Moved Permanently response is used for the permanent redirection of a resource.

For example, a resource that was previously at www.example.com/page.html has permanently moved to www.example.com/newpage.html.

If the move may only be for a shorter period of time and is likely to be changed or reversed, then alternatively a 302 Found status would usually be preferable.

What type of HTTP status is a 301?

A 301 is in the 3xx class of status codes which are redirection based.

Other status codes in the 3xx class include 300, 302, 303, 304, 305, 306, 307, and 308.

Is a 301 response good for SEO?

When used appropriately a 301 redirect can be fine for SEO purposes.

Generally speaking it is good for your site to respond with a 200 success code.

It is also a good idea to minimise the amount of 301 redirects users may encounter, such as when redirecting users from http://domain.com to https://www.example.com.
