I have a few basic questions I'm hoping someone can give me some insight on about link pyramids. For the example of this post, tier 0 is money site, tier 1 is web 2.0, etc. 1. Is it viable to make your tier 1 sites essentially micro niche sites if you have a large authority site? 2. Should you create multiple link pyramids, having each one target a couple keywords? Is this viable? 3. Does anyone have an example of what kind of content should go on a tier 1 site? I keep trying to think of why a site like that would occur naturally on the web, and I can't think of an idea what it even provides to the user. I want something that close to my money site to be useful to Google and the user.
