I got a kind of "hard to answer" question and I hope some of you more "experienced" could help me a little bit out. My question is whether or not backlinks from the same domain would help or not? For example we always talk about c-class IPs, we setup blog networks in different c-class IPs because most of us believe and we've seen that backlinks from different C-class >> backlinks from same C-class. And getting backlinks from the same domain would = to getting backlinks from the same c class ip. Not sure if there's a benefit to that. For example let's say we had a site called www.dogtraining.com. And we are getting backlinks from e.g. blogspot.com web 2.0s. There are different variations of this so there are more than 1 type of questions. Questions would be: 1) We have setup 2 blogger blogs: blog1.blogspot.com, blog2.blogspot.com. We backlink the same domain www.dogtraining.com with the same keyword "dog training" from the 2 blogger blogs. Now they are 2 different subdomains but still same ip AND we are targeting the same keyword. Would there be a benefit to this? Or useless? What about when you create 2 pages in blog1.blogspot.com and both pages backlink to our domain with the same keyword? Any use? 2) The second scenario would be blog1.blogspot.com uses "dog training" as keyword but the second blog blog2.blogspot.com backlinks using another keyword like "dog training videos". So in this case it's a backlink from the same C-class but with different anchors. Is there any use of this? Or still useless? 3) What about the other way round? This time we have 2 URLs to backlink to. 1 would be our homepage www.dogtraining.com, the second URL would be an inner page e.g. www.dogtraining.com/dog-training-videos. Would there be any use if we backlink from the same c-class ip to 2 different URLs but that are on the same domain? I know I may have made this sound complicated but I'm trying to figure out if it's useful to get backlinks from the same sites if it's for different keywords or for different pages of the same site. IF anyone has "Tested" knowledge on this please share!!! Thank you very much.
