Hi. I read something about this, and wanted to check what you guys thought. I'm hosting a blog on a 13 year old domain right now, I've posted a few articles and let them get indexed on their own. I've built some backlinks to the 13 year domain. Now I'm 301 redirecting it to my new domain, which is only a few months old. I read that this transfers like 70% of link juice, but it also convinces the serps that your new website is actually older. Is there any truth to this?
