I mean, the cost alone and the amount of time it's going to take to manage them!! AAAAAaaaarrrrrrrggggggggghhhhhhh. I'm new, forgive me, but here's my basic estimation of costs: Expired Domain = $10 (if you are lucky) Annual Hosting= $30 10 articles = $50 Total = $100/site (approx.) And that's just a site with 10 articles. Likely to get no traffic or SERP's. So, a 10 site PBN at $100/site is going to cost $1000 and will probably take a year to finish no? You can then use this PBN to rank some mid-competition keywords? Is this how it works? Or am I missing something?
