Reciprocal links cancel each other out from a search engines point of view but what counts as a recpirical link.
Do reciprocal links work on a site level or an individual page level?
If you where to say get an inbound link from site-a.com
to mysite.com
and then linked back from blog.yoursite.com
would that be reciprical.
I'm aware Google sees subdomains as different domains all together but in this instance is that the same?
