For example, if my main domain is a review site, lets call it www.MyReviewSite.com, and all the backlinks pointing to it are around the anchor text "review site."
Now, I'm adding on a section about a new niche which reviews this niches products... let's call it niche one.
So now I have www.MyReviewSite.com/Niche1 and the anchor text I use to direct to this is around "niche 1 review"
So my question is would these backlinks affect these pages separately, so that my niche1 review links would only affect that location, or will it be "spread out" over the whole site? And vice versa with the root domain.
A little bit hard to explain, but I hope this make sense.
I want to know so I know if I have to register a new domain or if I can just use a review site with folders and still get targeted links.
On another note, how does this same question apply, except using addon domains instead. (niche1.myreviewsite.com instead)
