So, I've got a website that I want to obviously do better with SEO. I've been reading a great deal on tier building, and this is what I've come to understand. You have the site you want to promote You make blogs/PBNs with the same niche and then fill this up with content and throw your main sites link in there Then you buy backlinks/guestposts/etc for the blogs/PBNs. Is that it? Am I missing something? What are things to watch out for when doing this?
