Mirrors in other areas?

Question

Search Engine Optimization

When buying a domain, it is possible to buy several zones at once, such as .com. org and so on.
The question is, if you purchase three five zones and send them to one site, how can this affect the position in the future, is it right to do this, or is it better not to do it, so as not to scatter traffic?
I ask experts to explain this situation.

Answer 1

If you decide to do this, then set up a 301 redirect to a single domain so that there is no duplication of content

Answer 2

It won't do anything in particular
Protects from the fact that the user types your domain in another zone, for this I usually buy ru and com always
Well, it protects my domain in another zone from being used by competitors

Answer 3

In theory it has no effect. But there is not much point in doing this if you do not have huge traffic and a distributed system of servers around the world. Unless you don't want others to take them.
One of the mirrors may be more popular than the others, depending on the search engine. That's all.
