This subject generate always controversy Bogart.
PR play very little perhaps nothing. I have seen many sites with PR0 ranking #1 for their keywords and the pages could be content or product with SEO link anchor texts properly made.
What difference does it make to have pages with PR or without PR if you rank for your keywords in position top #10? The goal is ranking high as much as you can to be visible. Now if you are selling links on PR pages that's unethical regarding Google guidelines. So what's the deal to try to manipulate the PR system beside selling links?
I don't think PR play anything into the site to make that the internal linking scheme work.
"The PR0 ranking #1 for their keywords" as you described may (1) already have PR but the pagerank hasn't been exported to the toolbar or (2) links that are higher quality due to either trust or authority.
A happy medium between content and links is always desirable. But whereas I have complete control over my own websites and favour a content heavy approach, many of my clients simply do not care about building content, they just want to get ranked for their keywords and fast.
For competitive keywords the backlinks get the site ranked. For the longtail keywords its the content.
In my opinion the backlinks are the most important. Once the site has some juice.
Wow, It's a pretty even split. I voted backlinks because it's not going to matter how good your content is if no one can find it. D:
I took some time to ask a few directories to update my deeplinks and they never responded to my requests. So now, I am not submitting anymore my deeplinks to them.
I know it is tricky, but wasting a lot of time to build deeplinks and consider that they will be efficient for a short period of the time, is not what I really want for my site.
There's a saying "Content is king" and because without content you can't have links.
