I have a layout similar to this, only it's not debates, so I'll use this as an example for the question.
As you can see, they have 3 different tabs, for rounds, comments and votes but these are all in one page, whereas in my case, I have different pages for comments and votes like this
example.com/post/1 <- main post's url example.com/post/1/comments example.com/post/1/votes
and both comments and votes are paginated, so there can be urls like this:
So I wonder how I should manage this kind of situation from the SEO perspective, won't the fixed part of the debate above the tabs considered a duplication? And what happens if I add a canonical link to let's say, comments page, leading to the main post's url, will the comments be indexed or only the main post's page will?
