I have an authority site i want to start a blog for, but i'm unsure whether to go for a subdomain (blog.mysitedotcom) or a completely new domain name specifically for the blog. I expect that because subdomains are considered completely separate sites from the main domain, it wont get any extra special attention from google just because it's related to my authority site, so i'm leaning towards a new domain. With a new domain i can host it on a new server and backlink back to the main site. The blog i'm starting will be updated almost every day for atleast a year with 200+ word posts, videos and images. What should i do? Subdomain or new domain?
