for this scenario I will use only branding anchor text homepage back links just for authority ...If you get the domains then do you use your PBN only for a certain niche? Let's say you want backlinks for "painting" niche and then you want backlinks for "car" niche. Will you use the same PBN to backlink to these sites? If so then the PBN has to have a very general theme/niche/area. How do you deal with that?
