I have 4 questions regarding PBNs: 1) when buying domains for it, should i be looking at pagerank or domain authority? for example we have site A with PR3, DA12 and links coming from 80 different websites/ips and site B with PR1, DA30 and links coming from 80 different websites/ips - which one is better? i know that the pagerank (as it's displayed to the public, in the green bar) is not accurate or updated frequently - but it's created by google while domain authority is not created by google but it's updated much more frequently - so which one is the better metric, considering 2 sites have the same (or really similar) link profiles 2) when setting up a pbn everyone talks about separate ips - question: if i have one dedicated server and buy different c-class ips for each site in the network, would that be ok? 3) what about nameservers? if the ip of each site is different but the nameserver is the same, would that be a problem? 4) when using the pbn, let's say i create 5-10 pages on each site just to build a foundation; after that, can i start posting, like once per week, on each site, posts with different links to the money site? like in week 1 link to moneysite.com/internal-page-1, in week 2 a new post linking to moneysite.com/internal-page-2 and so on? what's your strategy in using PBNs? Thanks!
