I didn’t quite realize that, figured that when you were viewing another instances’ content it was loading from that instance. I guess that means that Lemmy content across all instances has loads of redundant copies.
Maybe I’m misinterpreting what you’re saying, but lemmy.one has basically no content on it other than the 8 communities that @jonah has created or allowed there. The whole point of that server is to allow people to simply login and then participate in other instances from there.
That is all to say, lemmy.one would be one of the “smaller” instances from a standpoint of content to be indexed by Google.
