Sub domains take away the pagerank/link juice of main website?

[vtmoz]

Hi all,

I would like to know how sub domains will be collaborated with domain or main website in terms of authority, backlinks, link juice, etc...Link juice will be passed to sub domains from domain or vice versa? If there are large number of pages in sub domain, will that going to impact the ranking of main domain? Backlinks of sub domain are going to be a deciding factor for website ranking too?

Thanks

Hi,

My main domain and sub domain are treated as separate entities in terms of link equity and DA. BUT, my sub domain is a blog compared to my root domain being a much more concise service industry site. So they are pretty different in most ways. How closely related in terms of content is your sub domain compared to your root domain?

Since my blog attracts more links because of its article and restraint-free content, I try to funnel some of that link equity to applicable pages on my root domain, how well it works I am still uncertain of.
