Got a quick question here - I have multiple sites inside of a particular niche and I am building link profiles for each. In some cases I stumble upon a site where it's very easy to build backlinks. Up until now I have only set up one link to one of my sites when I backlink a domain, thinking it would be risky to backlink all of my sites from different pages of the same domain. This would make my backlink profile look very similar across each domain. Is this something to be concerned about or am I wrong?
