Hello, I have some expired domain with backlinks from high authority website ( 1 - 3 backlink with pr 2+). However, it is completely not related to my niche. So, I have 2 optional: 1. Redirect pages which has high pr backlink to homepage. Then add new niche content in expired domain and use it as money site. 2. Add new niche content in expired domain then 301 redirect main domain to subdomain. What is better for my case ? Anyone comment would be highly appreciated ! Thank you very much !
