None of these methods will affect the new domain name. The optimal transfer weight is 30 1 redirection. 3 and 4 should also have the effect of transferring weights, but not as good as 30 1. But no matter which is good, it is likely to waste the original domain name.

Suppose you are a user of a website. You have been using a common website before, but on that day, you didn't trust this website. You wouldn't have clicked on this website. But this will not affect your visit to the new website, even if the existing website is related to the new website.

But if the old website doesn't give you back trust, you won't trust it again, that is, you won't visit it. When you do any of the above steps, your website can only be equated with a channel. Users who no longer trust your website before will still not trust you. Later, I trusted your website users and saw that it was not your old website.

I wonder if this analysis will work?
