Referral system and 301 redirect, is it possible?

Question

Search Engine Optimization

All the best!
How is it preferable from the point of view of search engines to use a referral system:
site.ru/?ref=1 - Leave it as it is with a get request
site.ru/?ref=1 ---->301---->site.ru/
Question matured, since Yandex webmaster says that there are many different links with the same content.
Thank you!

Answer 1

so can simply prohibit referral links from being indexed in robots through disallow: *ref=*
and inside the site by putting rel="nofollow" on them so that the weight is not transferred?
I by the way, met both so, and so implementation.
through a redirect, I visually like it more as a user: I don’t see a referral tail.
but I like it more directly as a partner: I see the referral tail and understand that the links work.
IMHO, I'm more inclined towards the usual site.ru/?ref=1 without a redirect.
and who needs to simply shorten this link in the service.

Answer 2

Through robots, he invented the parameter to make it non-indexable, or to indicate the canonical on such pages
