I have heard a lot of talk thrown around about getting links on high PR domains resulting in high PR links, but from what I understand, this is not necessarily true. My understanding is PR is based off of possibility of a certain page being hit by how many links it has, not how many links the domain has. Lets say I have www.google.com/themadcracker.html, if that page only has one link pointing at it, the PR value for that page is not going to be high just because the domain is google.com, is this true, or am I missing something? -tmc
Based on what I think you are trying to say (but you made it a bit confusing), yes, the amount of PageRank juice given to your site denpends on the PageRank of the pages which are linking to you. Hope that answers your question. Still some people (like Angela) beleive in another ranking system (ranking factor), trust, in which case they say links from high PageRank sites might not carry a certain amount of PageRank juice, but instead they carry Trust. Yet none of them have made an actual case study or seem to base this argument on anything other than experience. Also, these are the very same people who are selling different kinds of packages on webmaster forums, so they kinda have to say it has an effect on your ranking.
high PR domains tend to have higher PR web pages. if you can get a link on a high PR domain do it, even if the page has no pagerank yet or pr 0. most likely, it will have PR sooon!
