Title might not be very self-explanatory. I've heard that a particular method in ranking is to rank a forum post by using it's pre-established domain authority and then linking to your site from there. I believe it's called the parasite method, and a very situational one. To explain my question I'll give an example. Say there is a reddit thread on a random subreddit and it is ranking for a keyword. I would, given that the situation is right, write a post on there linking to my site. In a situation where this is possible, how does google treat subreddits. As opposed to me making a thread/posting on one in a popular subreddit, could I make my own and generate the same result? Wondering if anyone has any knowledge on this or has tested at all, I hope I was able to convey my question well enough, appreciate any responses!
