We have a domain foo.com which was pointing to our main site bar.com (same IP address) Different content rendered for foo.com and bar.com
We have decided to retire foo.com. For the last while all foo requests have been 301 redirected to bar.com
Foo.com never built up much domain authority, so not sure if any value to the 301
We would like to formally retire foo.com and stop 301 redirecting all content to the equivalent bar.com page.
We could just change DNS to point to some holding page.
Is this a good idea. Anyone think we are deriving any link juice benefit from the inbound foo.com links?
