Hello, I am building a niche site based on an expired domain name with exact niche match. I put the emphasis on the relevancy. I grabed a domain name used in the same foreign language of my expected niche site for exactly the same keywords. An old domain name from a closed offline and online ecommerce. Good metrics, 700+ relevant old backlinks (mainly from directories). I grabed a second domain name with good metrics, TF, CF, DA and PA 15+ (but less good than my first domain name). Still in the same language and the same past activity and same keywords. What to do with this one.... May I do a 301 redirect to one of my epic post published on my all new niche site? May I do connect this second domain name to blogger and make a backlink to the niche site? Or may I create a customizable parked page from the registrar and link back to the homepage of the niche site? What will be the most efficient for the juice with the less effort^^ Thanks for your advices.
