Have read a lot of articles about Tier 1 PBN's, but need some clarification. I understand that the content on my Tier 1 needs to be nearly as good as my money site. HOWEVER, how much content do I need on those blogs? Are 3 or 4 posts sufficient? How much - and how often - should I post new content on those blogs, if ever? Just post x # of posts & leave the site, or treat it like a mini money site and post new content once a ??? week, month, year???
