What does this report contain?
Redirect chains which exceed the maximum number of redirects specified in Advanced settings > Report settings (default: 4 redirections).
How can this report be used?
Search engine crawlers will only follow a limited number of redirects in a chain, before giving up. A large number of redirects can also have an impact on usability, and isn't generally necessary. Redirect chains can be reviewed for opportunities to update to use fewer steps.
