also on steem in general the internal linkage, showing Google how posts are related does not tend to happen much.
I agree! Google goes through a content like a human does (with some exceptions).
Is it easily accessible? Google will find it quickly.
Do you show your readers (so Google too) the way to the content? They will find it, if it's not much work to be done.
Do others who Google appreciate say nice things about it (read: do you have backlinks on authoritative domains)? Google will appreciate it.
