The Redirects Report
The Redirects Report can be viewed as a lightweight version of the "Pages Linking Redirects" report. It shows all redirects and where those redirects come from and too. It's useful for seeing if a site has a lot of redirects, what type they are, and for looking for circular redirects.

Source URL
This is the URL that is redirecting to something else.
Type
The type of the redirect. 301 = permanent, 302 = temporary.
Redirect URL
Where the URL redirects to. If this is the same as Source URL then there is a circular redirect and there's a problem!
