Hi, I am running a game reviews site (not really the niche - but the concept is same) which has a LOT of reviews - tens of pages. I know my competitors are using PBN as they are dominating the SERP's with no visible backlinks. My question is, can I link to more than 1 review from a PBN site (to for example 2 reviews)? Because there are so many reviews that I can't afford to use PBN on all. Or is the competitors PBN to some reviews also raising the SERPs of other reviews because the site authority of the whole page rises?
