Domain forwarding or redirects for SEO?

[JHultqvist]

Hi all!

A client of mine owns several top level domains which are not in use, let's call them example.nu, example.de, example.net and so on. The current website is example.com.
When checking the technical status of the unused domains I realized that all but one are forwarded (via DNS) to example.com and only one has a 301 redirect.

Should I redirect all of them by means of 301 or let them stay forwarded? Very few of the domains have any other sites linking to them.

Any thoughts would be really appreciated!

Always go with a 301 redirect as long as your other urls do not have spam links associated with them, I consider it best practice to always do 301s.
