I've got a Tumblr blog for my main site, I use it more as a proper blog with articles and images, rather than just a tumblog.
The blog is mapped to blog.mydomain.com
.
Becuase of the ease of social reposting in Tumblr people often repost my articles (which is great - backlinks!) But all these links go back to my blog and not my main site which is a mydomain.com
does Google see blog.mydomain
and mydomain
as the same / linked item and is my main site getting the benefit of these links?
