Didn't know if this should be placed in the Marketing World or Google forum. But here it is.
I'm an owner of a blog network. We're about 6 months old. All of the established blogs are doing quite well, with a PR5 or higher. There's one blog with a PR problem.
Here's some data.
Link Popularity Check
Problem site (PR3): 3366
Site 1 (PR6) : 5478
Site 2 (PR5) : 3332
Site 3 (PR5) : 3302

Problem site (PR3): 810
Site 1 (PR6) : 699
Site 2 (PR5) : 470
Site 3 (PR5) : 250
Inbound link count from technorati.com
Problem site (PR3): 59 links from 27 sites
Site 1 (PR6) : 47 links from 16 sites
Site 2 (PR5) : 33 links from 10 sites
Site 3 (PR5) : 10 links from?
The PR problem wouldn't really be an issue because it's one of the top in terms of traffic. However, one of the advertising services (we think) uses PR to set ad prices. This has drastically affect the ability of the site to earn much.
The problem site was one of the first launched. The problem site updates almost daily with relevant, good content. All the sites are build with the same backend, so meta tags and format are identical.
So I'm wondering why doesn't this site have a higher PR?
The only thing I can think of is that this site received a number of inbound links within a short time period due to a photography challenge. Many of the linking sites used a quote of the invitation to join the challenge. Could this be affecting PR?
