Is NoIndex required for forum topic pages?

Question

Search Engine Optimization

The forum has threads of several hundred pages. Is it necessary to close such NoIndex pages, leaving only the first one available for the PS?

Answer 1

No, it is not necessary, and in general it is not necessary to close the pagination pages of the forums in every possible way, because. they contain unique UGC content. Unlike online stores, in which only products differ on pagination pages.
Add on 2, 3, 4, etc. pagination pages in title the name of the corresponding page, for example, "*topic title* page 2".
Well, look how on other forums, almost everywhere it is done that way.

Answer 2

well, in general, noindex only uses yandex, and even that doesn’t particularly support it, if the topics are different for you, then you don’t need to close it, and if not different, then put the canonical on the first one and that’s it
