Hello everybody, Now I have plan to build one authority website with multiple niches from 1 expired domain. Then I will do 301 redirect 20 other expired Domains to that domain. Although all domain is different niche but they are same broad niche. For example: Website 1: acnes niche website 2: weight loss niche website 3: Eye Diseases They are same health niche. I don't know whether they are de-indexed by google or not but when I type site:mydomain.com, i don't see any result. So, I have some question: 1. It is safe to 301 redirect multiple domains to 1 domain ? 2. Should I add some content to domains which used to 301 redirect ? It is ok to 301 redirect alone, not add content ? 3. If one of above domains was de-indexed by google, it will hurt my moneysite ? 4. You think I should do 301 redirect or PBN to my moneysite ? Actually, I prefer do 301 redirect because it is much easier than PBN I hope you can give me a advice. Thank you for helping me !
