Huston, I have a challenge! Can you please define and explain the differences, values and link quality based on the following criteria: Define the value of a one-way back link from a PR6 website (article on a dofollow blog) located on a PR7 Domain versus a PR0 website on a high PR7 domain. (All indexed) Define the value of a one-way back link from a PR6 website (article on a dofollow blog) located on a PR3 Domain versus a PR0 website on a high PR7 domain. (All indexed) Interesting scenario indeed isn't it? There is a lot of "dofollow blog lists" with high PR available, but how valuable are these blogs really if the open threads have zero or a low PR on the individual pages.. The big question is: Would a PR6 page on a PR7 domain be more valuable than a PR0 page on a PR7 domain? Then what about a PR6 page on a PR0 domain? What's the arguments to do or not to do a selection on page PR attached to the already mentioned high PR domain blogs out there? If a high PR page brings more power to the link building campaigns - why isn't his mentioned more often? It gets spider'ed more often and is a more powerful back-link source (!?): A high PR domain containing high PR pages has many links to themselves and will get spider'ed more often than a low PR page on a low PR domain. (True/false?) New pages/content will be faster indexed/re-indexed and updated in SERP which is important when dealing with "this week's offers" and more! (True/false?) Any facts or documentation on this scenarios?
