I've signed up for an account and taken out 2000 credits worth of blogroll links. The site is currently ranked 5th for its primary keyword and 6th for its secondary. This site generates about $100/day with an EPV of aprox $1.85. I figure a No 1 ranking is worth about $1000/day +-. Could be more as the earnings are CPS with a first drop attribution model.
The software is top notch, really straight forward to use. Was a little strange that I couldn't create a 'project' that had less than a 1 articles per day and 1 comment per day assigend. I was just looking for blogroll links, so don't know why that was necessary. Also I wanted their PR5 links, but the software wouldn't let me take any out (assume sold out), this should be stated prior to purchase.
The quality of the sites themselves, while having the represented PR, is pretty low. I wouldn't be surprised if they drop their PR quite quickly. They need to observe the site structure from the previous owners and attempt to emulate it or utilise some smarter redirects. URL/Title structures are just plain lazy and need to be set a little better when the WP installs are done. All-In-One SEO will do all this and adding the Google Sitemaps plugin will vastly increase the crawl rate of their properties.
I'll make another post in a couple of days with any positive or negative movement in SERPs for the test property.
