If I was able to write a blog post that was popular and it got lots of comments, then any links that I would have put in the body text would be devalued with each additional comment – even with ‘no follow’ being on the commenter’s links. So it would seem that in some sort of perverse way, the more popular (by comments) a page is, the less page rank it will be passing. I would have to hope that the number of inbound links it gets would grow faster than the comments it receives, a situation that is unlikely to occur.
But this leads to a question — if my husband wants to do a roundup of every Wagner Ring Cycle on DVD, that’s about 8 Amazon links on the page, all bleeding PR away from his substantive insights. If he, instead, wants to do a roundup of every Ring Cycle on CD, that’s about two dozen items worth discussing. The page would be very handy for users, and would involve considerably more effort on his part… but no good deed goes unpunished, and in the eyes of Google the page would be devalued by more than two thirds.
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content. Denver Page Rank Click Here
